List of Shōnen Onmyōji characters

This is the list of characters that appear in the Japanese light novel, manga and anime series, Shōnen Onmyōji.

Abe no Masahiro
(安倍昌浩)

Masahiro is the protagonist in the series. He is an Onmyōji in training and the grandson of the legendary Abe no Seimei. When he was young, Masahiro’s spiritual sight was so strong that Seimei temporarily sealed it away until he was old enough to properly use it. After meeting Mokkun, Masahiro regained his spirit sight and embraced his destiny as an Onmyōji in service to the emperor.

He is friendly and kind to both yōkai and people whom he seeks to protect from evil demons that had taken up residence surrounding the imperial capital. Although he is sometimes cocky and clumsy, there are moments when he utilizes powers beyond those of a mere apprentice, which is why Seimei claims he is the only one who can succeed him. Masahiro greatly resents being known only as Seimei no Mago (晴明の孫) and trains hard to surpass his grandfather.

He has two older brothers whom both are married and has families of their own. Narachika is the eldest in the family. His second older brother, Masachika is ten years older than him.

According to Ten’itsu, children in the Abe residence were often taken care by the twelve Shinshō. It was seen through flashbacks in the anime that Masahiro was taken care by Guren.

In addition to his magic, Masahiro later receives a sword called the Gōma no Tsurugi, a sword which was forged by Seimei which previously belonged to Suzaku. He was also given Kagutsuchi (軻遇突智) by Takao no Kami, flames that has the power to kill gods, in order to destroy the corrupted Guren.

In addition, he erased Guren’s memories that are about him, meaning that Guren will never remember the time when he met Masahiro in the form of a mononoke or the time when they were fighting demons together.

He cares a lot about his friends, his family and his love, Fujiwara no Akiko whom he vows to protect no matter what.



Abe no Seimei
(安倍晴明)  Akira Ishida (young)

The greatest onmyōji in the history of Japan, Abe no Seimei is the grandfather of Masahiro. He is in his 80’s and he has twelve shikigami called the Shinshō whom he calls his friends under his command and is able to protect his soul, which takes the form of his younger self, outside of his body in order to aid Masahiro in combat. However, by doing so leaves his body defenceless if an enemy attacks.

He constantly needles Masahiro to push him further in his journey as a sort of reverse psychology, which causes Masahiro to refer to Seimei as a "tanuki" or raccoon dog.

Rumour has it that Seimei's mother was not human but a powerful fox spirit, which may explain why he is so powerful. Despite showing such a happy attitude, there were two moments of his life that he was sad, the first when he couldn't save his only best friend, Ryūsai and secondly the death of his wife, Wakana whom he loved deeply.

The character is loosely based on a real person of the same name.

Abe no Wakana
(安倍若菜)

Wakana is Seimei’s wife and Yoshimasa’s mother. She died when he was only two years old due to an illness. Although she died a long time ago, her spirit hasn’t cross to the other side.

Masahiro also met her for the first time in the final episode and not knowing that she’s his grandmother. He met her in the spirit world when he was ready to cross over to the other side, and she invites Masahiro to sit beside her. There she tells him that her lover hasn’t come and that’s the reason why she couldn’t cross to the other side just yet.

Wakana also reminded Masahiro of the person that is precious to him and managed to persuade him to return.

Abe no Yoshimasa
(安倍吉昌)

Yoshimasa is Masahiro's father and Seimei's youngest son. He is married to Tsuyuki and has three sons: Narichika, Masachika and Masahiro. He has a doctorate in stargazing and is a prominent figure in the onmyō world.

However, he is not as powerful as Seimei or Masahiro (after he realizes his potential). Yoshimasa realizes that Masahiro is the true heir to Seimei, as acknowledged by Guren, as he is the only one not afraid of his aura.

He is a kind and supportive father, makes up excuses for Masahiro at the onmyō dorms when he goes to fight demons and purposefully ignoring his nightly escapades.

Abe no Tsuyuki
(安倍露樹)

Tsuyuki is Yoshimasa’s wife and Masahiro’s mother. She knows about Masahiro fighting demons at night but doesn’t say anything to him because she wants him to tell her personally.

Later in series, Tsuyuki also teaches Akiko things that girls her age do, such as going shopping in the market and sewing.

She knows Yoshimasa very well; she could tell that he’s worried about Masahiro going to Izumo to kill the corrupted Guren even when he doesn’t tell her. Yoshimasa even went as far to say that the thought on how well Tsuyuki understand himself frightens him.

Abe no Narachika
(安倍成親)

Narachika is Yoshimasa's eldest son and Masahiro's oldest brother. He has an easygoing personality and is, personality wise out of the three brothers, most similar to Seimei.

He married into his wife's family and has two sons and a one year old daughter named Kōhime, (小姫). Narichika has a doctorate in calendar and date studies, making him a highly recognized figure in the dorm.

He cares for his family and Masahiro a lot.

Fujiwara no Akiko
(藤原彰子)

Akiko is an imperial princess and the daughter of the minister of the left. She and Masahiro first meet in the Imperial Palace after his coming of age ceremony and the two become good friends after he saves her from a demon attack. As the series progresses, both of them fall in love with each other.

Akiko is special, as she possesses the Kenki ability (the ability to see demons). Moreover, because of this, during the beginning of the series, the foreign demons constantly attack her to deliver Akiko as a sacrifice to their master. They manage to capture her but Masahiro and his allies were able to save her, but not before the demons gave a curse wound on her hand.

Halfway through the series, Akiko's father attempted to introduce her into the imperial court as a wife for the Emperor, thereby separating her from Masahiro forever. In her moment of sadness, Kyūki was able to put a powerful curse through her wounded hand. While the curse was eventually removed, according to Seimei the after-effects of the curse were so serious to Akiko that an onmyōji was required keep the curse from overwhelming her.

As a result, she wasn't sent to imperial court -as that would bring bad luck to the Emperor- so her half-sister Shōko, who looks the same as her, was sent into the palace in her place. Akiko was instead sent to live with Seimei's family to deal with the curse under the identity as distant relative of theirs. (There are suggestions that Seimei tricked Akiko's father into thinking that so she and Masahiro could remain close, since he knows about their feelings for each other. However, it's also revealed Seimei was having difficulty in finding an auspicious date to send Akiko to court.)

It should be also noted that her Kenki ability is stronger than both Seimei and Masahiro because she was able to see a spirit that was possessing Masahiro while neither Masahiro nor Seimei could.

At the Abe residence, Akiko remains a strong help to Masahiro and helps around the house, learning to do things what an ordinary girl does, like going shopping by herself thanks to the help of Tsuyuki, Masahiro's mother.

During the middle of the series (episode 10), Masahiro promises Akiko that he will show her fireflies at Kifune mountain next year at summer time. In the final episode of the anime, he is shown fulfilling his promise.

Fujiwara no Yukinari
(藤原行成)

Yukinari is the minister of the right to the Emperor, whose primary duty is the management and upkeep the imperial capital.

Yukinari takes a liking to Masahiro from the moment they meet, and constantly encourages him to advance in his studies because he knows he will be a powerful onmyōji like Seimei, which of course promotes a high amount of jealousy among Masahiro's peers in the Onmyō dorms. Seimei helped him long ago and because of this Yukinari offered to be Masahiro's guardian at his coming of age ceremony in return.

During the series, he was cursed by a vengeful spirit who had mistaken him for his grandfather, but the spirit was later exorcised thanks to Masahiro.

He also seems to be aware of Masahiro's activities in fighting demons.

Fujiwara no Toshitsugu
(藤原敏次)

Toshitsugu is two years Masahiro's senior; he works at the Onmyō dorms with him. He is a diligent worker who values effort and hard work above all else. He has a nickname, Tosshi (とっしー)

He was the first person who talked to Masahiro but after a misunderstanding of seeing Masahiro at night when he was supposed to be at home on rest. Toshitsugu's attitude became harsh and critical, saying he shouldn't do as he wishes just because of his family's influence.

Toshitsugu shows promise as an onmyōji by "normal" standards (not compared to Seimei or Masahiro). He does not know of Masahiro's power, but gets suspicious after a cloaked Masahiro saved him.

He was possessed by a vengeful spirit summoned by Kazane in the Kazane arc and placed a curse on Yukinari who had taken care of him since he was young. Masahiro eventually breaks the curse where he had no memory of the incident.

The Twelve Shinshō
Jūni Shinshō (十二神将)

The twelve Shinshō have been in existence for a very, very long time and can be considered as gods of the lower rank. Currently they fall under the command of Abe no Seimei, the greatest onmyōji of all time. Unless Seimei summons them, they usually reside in the spirit world of the Gods.

As told by Takao no Kami, the goddess of Kifune Mountain, the twelve Shinshō are special as they were actually created by peoples' dreams. Over time, people's dreams and imaginations were transformed into the twelve Shinshō, giving them unique forms and personalities.

They can be considered as the children of humans. Hence, there’s a golden rule that they must never harm a human let alone kill one. If they break that rule, they will lose their souls and become demons.

Although they are gods whom possesses strong powers, they can be injured, feel pain and lose their lives. When one of them dies they will be reborn instantly as people's dreams never stop giving them their form but they will forget their past self and continue on as a completely different god.

Mokkun/Guren/Tōda
(もっくん), (紅蓮) (as Guren)  (as Mokkun for TV anime and side story drama CD)

Guren is one of twelve Shinshō in service to Seimei, who gave him his current name, after he pledged his servitude. His original name is Tōda, (騰蛇). However, the other Shinshō still address him by his original name. Only Seimei and Masahiro call him Guren. The form he takes most of the time is an ayakashi although Masahiro considers him a mononoke, whom Masahiro named Mokkun. Because he's invisible to anyone without a spirit sense, Mokkun frequently plays tricks on people who annoy him, much to Masahiro's chagrin. It was also shown in the anime that Guren dislikes babies, because according to him, babies often cry for no reason. However, Masahiro disagrees, saying that Guren was merely afraid that the children who saw him would hate him.

From the time Masahiro was a baby, Guren watched over and protected him, as Masahiro was the only person who wasn't afraid of him. Because of this, despite how they constantly bicker with each other, Masahiro and Guren share a deep sense of friendship and trust between them and both are willing to lay down their own lives for the other.

It is also mentioned that Guren is one of most feared summon gods, possessing the power of controlling the fires of Hell. Seimei also created a golden ring to wear around Guren's head to keep his own strength from overwhelming him.

Since Masahiro doesn't fear Guren, Seimei cites this as the proof his grandson is the only one compatible to be his successor. In the form of Mokkun, the familiar is able to erect barriers and project crescent shaped blades of energy; in the form of Guren, he attacks with blasts of fire and a trident.

In the past, Seimei’s best friend Ryūsai who ordered Guren by using the Baku-kon spell, a spell that could forcefully control anyone’s heart. He used it on Guren to kill Seimei and after that kill him. In addition, because of that incident the other Shinshō don't trust him. Nevertheless, that began to change with Masahiro's help, as stated by Kōchin.

Later in the series, he is corrupted by Chishiki no Gūji, losing his soul and becoming a cold-blooded monster who almost leaves Masahiro to die. It is later revealed that he’s a slave of the Underworld, as he controls the Fires of Hell. His blood was required to break the final seal of the gate to the Underworld.

At the end of the anime, Masahiro revives Guren; saving his life in exchange for Guren's memories of Masahiro being sealed away, so he would not have to remember and regret the terrible things he has done. Despite Guren having no memory of who he is, Masahiro felt that this was better than seeing him die. However, Guren is sill one of Seimei's familiars. As such, he is under orders from Seimei to continue to look after Masahiro.

Kōchin
(勾陣)

Kōchin appears as a mature-looking woman, about 25 years old with shoulder-length black hair. She is ranked second strongest of the twelve in attack power, after Guren. She specializes in close range fighting with twin sai.

Unlike the others, Kōchin does not resent Guren as much and is actually his close friend shown in that he refers to Kōchin as 'Kō'. When Masahiro asks him about this, he refused to respond.

She has also watched over Masahiro when he was a baby together with Guren. She is very observant and has a clear grasp of all of the Shinshō's personalities. She is also very good at noticing small details.

Her second name from Seimei is Keito, (慧斗)

Rikugō
(六合)

Rikugō's primary role is to be the on-call bodyguard to Seimei but he will leave Seimei's side to aide Masahiro should he be ordered to. His sense of loyalty is so strong that he was willing to put aside his doubts regarding Masahiro's abilities and accepted him as Seimei's successor on little more than his master's assurances.

He differs from the other Shinshō in that he rarely use magical attacks, preferring instead to fight opponents with a barbed spear. He can also use his cape as a shield and create an explosive 360-degree shock wave of air by striking the ground with his weapon. He also has a chain that was used against the corrupted Guren but he overpowered him.

Rikugō is a man of few words and only speaks when he must. The only way to notice any change in his emotions was through his eyes. This began to change, however, after he met Kazane whom he fell in love with. He saved Kazane's life twice. The first, when she was swallowed by a demon and there was another time when they were in the underworld.

He began to show emotions soon after that. He was furious when she was killed. Just before she died, they shared an emotional embrace and he revealed to her that his name is Saiki, and that she is the only one he told his name to.

Seimei gave him the name Rikugo, and only Seimei and Kazane know "Saiki" Saiki (彩輝) as well.

Seiryū
(青龍)

Seiryū is stubborn, anti-social and has a bad temper. He holds a deep hatred for Guren due his attempted murder of Seimei and considers Masahiro to be unworthy to be Seimei's successor.

Seiryū even went as far as to say that if Guren ever harms a human again, he would personally kill him.

He attacks with blasts of lightning and fights with a large two handed scythe. His second name from Seimei is Shōran (宵藍). Seiryū cares about Seimei's wellbeing more than any of the others. However, he always shows his care through anger.

Suzaku
(朱雀) (Japanese),   (English)

Suzaku is a fire user like Guren. Unlike his destructive flames, Suzaku's flames are used to purify evil spirits. He uses a heavy-bladed Zanbato to slash his enemies.

Suzaku has bright red hair and wears a white strip of cloth around his forehead, which was Ten’itsu's. He is very much in love with Ten’itsu and is fiercely protective of her due to her wound transfer ability, going as far as to hit Masahiro after Ten’itsu saved him.

The reason he cares about her was that Ten’itsu’s past self was Suzaku's best friend who was reborn right before his eyes after she died. Not wanting to lose her again, he becomes her protector.

His sword was later lent to Masahiro so he can use it with the power to kill gods.

Ten'itsu
(天一)

Ten’itsu has the appearance of a young woman with long blond hair. The earring she’s wearing belongs to Suzaku. Unlike the other members of the Shinshō, she specializes more in magic than combat, particularly healing and clairvoyance. However, she is still able to create defensive shields with her magic.

When someone has a very serious wound, she heals it by transferring the wound on her, something her lover and fellow Shinshō Suzaku distresses over.

Ten’itsu has another name, Tenki, (天貴) which only Suzaku calls her by. She is usually seen protecting Akiko or just keeping her company. She is the only Shinshō of the twelve that has died before. Her past self wore her hair short and was loud and energetic.

Tai’in
(太陰)

Tai’in is a wind user who resembles a young girl with high pigtails. She also has a childish personality despite living for so long. She was said to be rash by a fair few of the Shinshō.

Tai’in attacks with mini tornadoes and can also use the wind to communicate and pass messages. She can also 'read' the wind to know what's happening at other places but she's not good at it.

Because of her personality, she is often at the receiving end of one of Byakko's lectures with the current record that lasts 8 hours. Tai’in does not like slimy things and often appears with Genbu.

She can create a tornado to transport people to other places but the ride is usually very rough. A recurring gag in the series is that whenever she uses this, Masahiro and Genbu falls on the ground with only the other Shinshō remaining standing.

Genbu
(玄武)

Genbu resembles a young boy of about 13 years old. Although not possessing much ability in combat, Genbu specializes in defence and making barriers. However, out of the four people that can make barriers, his ability is the weakest.

He is a water user and has a water mirror that allows the user to see things happening far away. He can also use this mirror to communicate with fellow water user, Tenkō. Genbu is often seen with Tai’in who he constantly berates on some of the things she does.

Tenkō
(天后) (anime only)

Tenkō is a water user like Genbu. She appears to be about the same age as Kazane and has long, light sliver hair. Tenkō is the weakest out of the eight fighting and is angry with her for that. She gets along well with Kōchin.

She is about as stubborn as Seiryū but has her gentle side. She first appears in the 20th episode & finally had her first speaking role in the final episode of the series.

Taijō
(太裳)

Taijō is a man with green hair. He's appears as a very peaceful, respectful man who always call Seimei's family with the suffix "sama".

He first appeared in the 20th episode & finally had his first speaking role in the final episode of the series.

Byakko
(白虎)

Byakko resembles a strong middle-aged man with grayish-green hair. Like Tai’in, he is a wind user but his wind is more 'gentle' and travels slower than Tai’in's. He treats Tai’in and Genbu like his children.

He is also the only one that can keep Tai’in under control.

Tenkū
(天空)

Tenkū resembles an old man with a long beard. He’s the governor of the twelve Shinshō and rarely leaves the spirit world.

He also has the strongest ability of making barriers and defence among all the Shinshō. This was seen with the fact that he can immobilize enemies without leaving the spirit world.

He also makes all the Shinshō's weapons. He first appears in the 20th episode & finally had his first speaking role in the final episode of the series where he talks to Takao no Kami about Masahiro’s willingness to save Guren at the cost of his life.

Takao no Kami
(高淤の神)

She’s the dragon goddess of Kifune Mountain. She is a very powerful god that the twelve Shinshō including Seimei respect. When Kyūki and his demons came to Japan, he manipulated Akiko's cousin Keiko to seal her so that he and his demons could hide at Kifune Mountain without interference. Masahiro who used his magic to break the seal later freed her.

As a sign of gratitude, she saves Masahiro's life after a possessed Akiko stabs him. Later in the series, she helps Masahiro and his companions when the capital is in trouble. She also took over Masahiro's body to discuss important issues with Guren regarding Masahiro but later decides to tell the latter herself in her human form.

She usually appears as a white dragon but later appears as a purple haired woman in her 30's usually telling anyone to call Takao when she is in her human form. Even so, her official name is Takaokami no Kami (高龗神).

She later gave Masahiro Kagutsuchi (軻遇突智), flames that has the power to kill gods in order to kill Guren whom has been corrupted.

Kuromanosuke
(車之輔) (drama CD only)

A yōkai who resembles a carriage with a wide-mouthed ogre's face mounted on the left wheel.

Masahiro first encountered Kurumanosuke while patrolling the streets of the capital and almost exorcised him for allegedly attacking a human, but spared him after realizing Kuramanosuke was only trying to help a drunk who had passed out in the street.

Later, Kuramanosuke accepted Masahiro as his master and serve him by taking him to places he wants to go. When the capital was invaded by demons from the Underworld, it was Kurumanosuke who help hid the Zakki in his carriage to save their lives.

The Zakki
(雑鬼)

The term 'zakki' is used to refer to the demons of lower rank. Since Masahiro exorcised Ban Ban, a demon that was attacking the Zakki, they now act as informants for Masahiro, telling him of any strange happenings or sightings.

In the anime, the Zakki are usually represented by three demons; a lizard with three eyes, a yellow skinned gremlin and a pink, round ball. The Zakki usually appear by suddenly dropping out of the sky and landing on his head and calling him "Seimei's grandson" much to his dismay, a running gag in the light novels and anime.

Kyūki
(窮奇)

The leader of the foreign demons, Kyūki's form is that of a gigantic winged tiger with horns and saber fangs but can also assume the shape of a massive demon bull. After losing his territory in China to a rival demon, Kyūki and his army of demons seek to establish a new territory in Japan, specifically around the imperial capital.

Although possessing incredible strength and power, Kyūki is hampered by a massive wound on his throat inflicted by the demon which chased him from China and which requires the consumption of someone possessing great spiritual power in order to heal. As Seimei is too strong for him to attack, Kyūki targets Masahiro instead but also pursues Akiko as well for her Kenki ability and because beautiful longhaired girls are his favorite food.

He usually has his followers attack his enemies and uses his enemies’ desires to control them. He is eventually killed when Masahiro uses the Gōma no Tsurugi to stab him though the chest in order to transmit a spell directly into Kyūki's body.

Fujiwara no Keiko
(藤原圭子)

Fujiwara no Keiko is Akiko's cousin and a member of the Fujiwara clan. She was once engaged to a man she was about to marry but the man bewed another woman instead. What was humiliating and angered her was the fact that the woman he married was from a lower noble family and had begged the man to marry her.

Heartbroken, Kyūki uses that to his advantage to possess her with the promise that if she helps him, he will curse the wife of his beloved’s face that will force him to leave her and to be with Keiko again.

While the possessing made her sick and bedridden, she was able to leave her home using her cursed spirit to travel. She helped Kyūki by sealing the dragon goddess of Kifune Mountain so his army could hide the mountain.

She was willing to do anything to be with the man she loved, even killing anyone who gets in her way and sacrificing her cousin Akiko.

Seimei finally exorcised her possessed spirit and she wakes up in her home not remembering what had happened.

Ban Ban
(蛮蛮)

Looking like a giant-bodied rat with the head of a turtle, he was one of Kyūki's followers. He was also the demon that made Masahiro realize that the demons he was fighting were from China.

He first appears in Masahiro dreams and later attack the Zakki in their hideout where he dies bleeding from his injuries from fighting Guren and Masahiro.

Gaku
(鶚)

Gaku is one of Kyūki's advisors and lieutenants to his followers. It always looks down upon their opponents believing all of them are weak. The other advisor is Shun (鵔)

It was one of the demons whom were responsible for putting a cursed wound on Akiko's hand. Due to his overconfidence, Masahiro and the Shinshō finally killed them.

Kazane
(風音)

She’s initially introduced as a daughter of Ryūsai. She is a formidable fighter, able to use magic and weapons as well. She is able to stand her ground and even defeat Seiryu and Genbu in a 2-on-1 battle.

She has a deep hatred for Guren because she believes that he killed her father. She has a crow for a companion named Kai and cares very deeply for it. She and Rikugō seem to have feelings for each other.

Rikugō has the most confrontations with her and ended up falling in love with her. He tried to talk some sense in her that Chishikii no Gūji is just using her to open the Underworld but she replied that it is of her own free will.

It is later revealed that she is not really Ryūsai’s daughter but in fact the daughter of Chigaeshi no Miko. Chishiki no Gūji kidnapped her when she was young and had her memories sealed. She was trained by Ryūsai and was told a lie that Seimei and Guren were responsible for her parents’ death.

Unknown to her, she was secretly used to open the first gate of the Underworld due to the fact only those related to the Priestess can open the gate.

When she found out the truth and was weakened by Chishiki no Gūji to open the gate, she tried to escape from the underworld demons where her pet crow, Kai sacrificed his life by teleporting her away. Sadly, it was all in vain as she was killed by a demon who stabbed her through the chest.

Despite being a villain, she was still a good person since did care about Princess Nagako and tried to send her back to her family as she regretted kidnapping and using her in the first place.

Her last moments before dying were with Rikugō who held her in his arms where she learned his real name. Her necklace was used to defeat Chishiki no Gūji and was later given to Rikugō by her mother who later brought her daughter's body back to their home.

She’s mother of Kazane. She resides in the Overturned Earth, a realm between the human world and the underworld where the guardians of the underworld protects her and her family, large animals whose duty is to serve the Priestess and protect the seal of the Underworld.

Fifty years before the Kazane arc began; she sought the help of onmyōji Seimei and Ryūsai to help her seal the gates of the underworld since the seal was getting weaker. However, Ryūsai fell deeply in love and kidnapped her instead.

She later left Ryūsai to go back to the realm but was kidnaped by Chishiki no Gūji. He sealed her into a frozen rock since he couldn't get her to open the Underworld gate; instead, he used her daughter, Kazane. She was later found and rescued by Seimei.

However, she was later in grief when she found out her daughter, Kazane died. She later brought back her daughter's body back to her home and gave Rikugō her necklace as a sign of gratitude for protecting her daughter.

Ryūsai Enoki
Enoki Ryūsai (榎岦斎)

Seimei's only best friend and a powerful onmyōji. While Ryūsai was not as powerful as Seimei, he had learnt the Baku-kon spell. The Baku-kon spell could forcefully control anyone’s heart, which is a spell that Seimei dislikes.

Fifty-five years ago, he accompanied Seimei to Izumo to check a disturbance there despite objection by Seimei not to follow him. There, he and Seimei met Chigaeshi no Miko who he fell deeply in love with. He was soon manipulated by Chishiki no Gūji to kidnap the Priestess and break the seal of the Underworld and made to believe that by doing so, he could get the Priestess all for himself.

When Guren and Seimei tried to stop him, he uses the Baku-kon spell on Guren and made him try to kill Seimei. Guren finally killed him, but his body was used by Chishiki no Gūji's soul. He uses his body to help him in his plan with the promise that he could still get the Priestess all for himself. His body was finally destroyed by Rikugō & Seimei and his spirit thanks Seimei for freeing him.

Chishiki no Soushu
Shrine Priest of Knowledge (智鋪の宗主)

He’s the real villain that’s been controlling Kazane and Ryūsai. Seimei and his Shinshō fought him once before many years ago, but now he has returned to open the Gates of the Underworld.

He is also called by the name of Chishiki no Gūji (智鋪の宮司) or Chishiki no Chi no Kami (智鋪地神)

Rikugō was the first one to realize he was back because he heard Kazane talking to him through a second head protruding from her crow, Kai.

When he was mortally injured, he transferred his soul into Ryūsai's body to continue his plans. He trained Kazane and lied about what happen to her parents so she would help him open the gates of the underworld.

He later also controls Guren since his blood was needed to break the final seal. He was finally killed, ironically by Kazane's necklace.
