Story
The series, set in the Heian era, Abe no Masahiro is the grandson of the great onmyōji, Abe no Seimei. Seimei, who passed his teachings on to his grandson, Masahiro who has lost his sixth sense and the ability to see spirits. Masahiro constantly feels resentful for being in his grandfather's shadow.

He is one of the twelve shikigami called the Shinshō (神将), who has pledged his loyalty to Seimei and is helping Masahiro to surpass his grandfather.

He also has to keep his promise to protect Princess Akiko of the Fujiwara clan.

Someone is trying to open the gate to the underworld, events from fifty-five years ago reoccur, and Guren as well as Masahiro must undergo the ultimate test.

Abe no Masahiro
(安倍昌浩)

Masahiro is an onmyōji in training and the grandson of the legendary Abe no Seimei. When he was young, his 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.

He also has a relationship with Akiko.

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

Guren is one of twelve shikigami 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 shikigami still addresses him by original name. Only Seimei and Masahiro call him Guren.

The form he takes most of the time is 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. In episode 18 of the anime, it was shown that Guren tries very hard to avoid children, goings as far as to avoid entering dwellings with children even when his help is needed. According to Guren, the reason behind this is that children cry for no reason. Masahiro later notes that Guren's apprehension does not stem from the crying itself, but that Guren does not want the children to "cry at him" demonstrating that he is feared by loathed by everyone.

Masahiro later tries to comfort him by showing him that children are not afraid of him.

Abe no Seimei
(安倍晴明)   (young)

The greatest onmyōji in the history of Japan Abe no Seimei is the grandfather of Masahiro. He has twelve shikigami called the Shinshō under his command and is able to project his soul, which takes the form of his younger self, outside of his body in order to aid Masahiro in combat.
