Triangle Heart (とらいあんぐるハート, Toraianguru Hāto^?), abbreviated as Toraha, is a series of eroge and OVAs that is most noted for its spin-off series, Magical Girl Lyrical Nanoha. The name comes from the fact that each game focuses on a "triangle" of one boy and two girls, though there are many other heroines. The first game in the trilogy was published December 18, 1998.

The Triangle Heart: Sweet Songs Forever (とらいあんぐるハート～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 three games were later republished into a single DVD title on 14 June 2002.

Three manga were made for the series. Two versions of Triangle Heart 3: Sweet Songs Forever were published, one by KSS (4 volumes), and the other by SOFTBANK Publishing Inc. (1 volume). Sweet Songs Forever 4 koma KINGS was published by Studio DNA.

Years ago, professional bodyguard Shirō Fuwa and his client Albert Crystela were killed by a terrorist organization that is known by 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.
