Triangle Heart: Sweet Songs Forever

Fiasse Cristela is a celebrated singer preparing for another charity world tour while running the singing school inherited from her mother. Behind the bright stage, however, dangerous people begin targeting both Fiasse and the inheritance left to her.

Ellis and the sword-skilled siblings Kyouya and Miyuki Takamachi are drawn into protecting their childhood friend as the tour approaches. With threats following Fiasse from one destination to another, the group must keep her safe without allowing fear to silence the music she has chosen to share with the world.
