Triangle Heart (とらいあんぐるハート Toraianguru Hāto?), abbreviated as Toraha, is a series of H games and OVAs that is most noted for its spinoff series, Magical Girl Lyrical Nanoha. The name comes from the fact that each cast focuses on a "triangle" of one boy and two girls, though there are many other heroines.

The Triangle Heart ~sweet songs forever~ OVA, based on the game Triangle Heart 3, focuses on a boy named Kyōya Takamachi who, with his cousin-turned-sister, vows to protect a childhood friend from a mysterious terrorist organization.

There have also been two fanbox games, Love Love Toy Box, based on Triangle Heart 2, and Lyrical Toy Box, based on Triangle Heart 3.

The 3 games were later republished into a single DVD title in 2002-6-14.

3 comics were made for the series. Triangle Heart 3 ~Sweet Songs Forever~ were published by KSS (4 volumes) and SOFTBANK Publishing Inc. (1 volume). Sweet Songs Forever 4 koma KINGS was published by Studio DNA.


OVA Triangle Heart 3 ~sweet songs forever~

Years ago, professional bodyguard Shirō Fuwa and his client Albert Crystela were killed by a terrorist organization that bears the symbol of a clover leaf. Albert's daughter Fiasse blamed herself, but then grew closer to the Fuwa (now Takamachi) children, Kyōya and Miyuki, and decided to use her gift of singing to help the world. But now that they have grown up, Fiasse herself is being targeted by the same organization. Kyōya and Miyuki, swearing to protect Fiasse, become professional bodyguards like their fathers.


Triangle Heart

Main Character

  • Shinichirō Aikawa (相川 真一郎 Aikawa Shinichirō?)

The hero of this game, Shinichirō is short, bland and very inept at dealing with women. However, what he lacks in tact, he makes up for with a sincere desire to help the people around him. He is a beginner in the art of karate and proud of his cooking skills.

Major Heroines

  • Yuiko Takashiro (鷹城 唯子 Takashiro Yuiko?)

This young girl has a vast talent for martial arts, but does not put it to use. She is normally very naive, but when she speaks one-on-one with Shinichirō, he can tell that she actually has a sharp mind. She is shown to be inept at domestic activities such as cleaning.

  • Kotori Nonomura (野々村 小鳥 Nonomura Kotori?)

Kotori lives with Shinichirō as a childhood friend. She is very small and is often mistaken for a student in elementary school, which offends her to the point of a complex.

  • Izumi Mitsurugi (御剣 いづみ Mitsurugi Izumi?)

A classmate of Shinichirō, and a tomboy who dresses in the boys' uniform. She treats Shinichirō as a buddy and considers herself "one of the guys", but she has a deep and caring soul which others consider feminine. Izumi trains especially for patience, and lives alone.

  • Sakura Kidō (綺堂 さくら Kidō Sakura?)

Shinichirō's junior, Sakura is half-German, half-Japanese. She is very sickly and spends a lot of time in the nurse's ward. Despite this, she is seen as "cool" and is the most popular girl in school. In Triangle Heart 3, she is Shinobu's aunt and the creator of Noel.

Main Characters

A kind and butiful person, Kyōya is the hero of the story. He has inherited the Mikami-ryuu and Fuwa-ryuu sword styles and is teaching his sister Miyuki. Kyōya is dedicated to his sword and is quick to prove wrong anyone that doubts an "outdated" weapon.

  • Miyuki Takamachi (高町 美由希 Takamachi Miyuki?) (Voice: Satomi Kodama)

Miyuki does not really feel any passion for sword fighting, but does it because she wants to honour Shirō and protect Fiasse. Her father and extended family were killed by the clover-leaf terrorist organization, so she was adopted by Shirō while her biological mother sought revenge.

Fiasse is a world-renowned singer and heiress, and the childhood friend and older sister figure of Kyōya and Miyuki.

A character from the OVAs, Ellis is Fiasse's real (read: paid) bodyguard, and jealous of Kyōya and Miyuki. However, her reluctance to see them in her post is more than just a fear of being replaced. They are part of her past, a past which she would like to deny...

  • Shinobu Tsukimura (月村 忍 Tsukimura Shinobu?) (voice: Yuki Iwata)

The "main heroine" in the dating sim sense, i.e. Kyōya's canonical girlfriend. Shinobu is almost as rich as Fiasse, but her mysterious parents were disliked by the rest of the family, and after their death, she was left alone. However, a kindly aunt (the grown-up Sakura Kidō) made her a guardian in Noel. Shinobu knows Kyōya from school and works at his family's cafe, Midori-ya. She also appears to have an interest in mechanics.

Major Heroines

She practices bōjutsu. Like Akira, she is a good cook. She calls Akira "monkey".

Kuon is Nami's pet fox, who has an affinity for Nanoha as well. However, she is actually a kitsune and transforms into a foxgirl. Kuon has lived for centuries and once flew into a rage after her human lover was killed. She was cursed to live forever, but was sealed into the form of a helpless young fox until the Kanzaki family could become powerful enough to either save or destroy her. Kuon eventually learns to love humans again.

Known as Alisa Bannings in Magical Girl Lyrical Nanoha, Alisa is a bitter young girl around Nanoha's age. She holds a grudge against all people, but somehow befriends Nanoha after Kuon has turned good. Alisa is actually a wandering spirit seeking rest after she was kidnapped and brutally murdered. In the Lyrical Toy Box game, even though she has passed to the spirit realm, her influence is felt everywhere. Nanoha meets Lindy at Alisa's grave.
