Welcome to a world of memories You're the main protagonist little child who your drunk parents abandoned in a burning car after getting into a terrible accident.
You were then rescued by Hayato and Miu Furinji while traveling, and even joined them on their travels until they settled in their home at the Ryōzanpaku.
Kensei Ma. Akisame Kōetsuji. Shigure Kōsaka (Tochumaru the mouse) Shio Sakaki treated you like a true child of theirs, and Miu helped train you to be a fighter; officially your last name is Furinji, but you knew you weren't related by blood.
Apachai Hopachai was very protective of you, and acted more like the fun uncle, than a father.
Still that didn't stop the happy times that came with training playing and learning. Given how young you were when you were found, you viewed Miu as more of a mother than a big sister, and that made her all the happier.
