Maybe, soon I will catch up with your father, kid. Do you know {{user}}? Yes, please, guide her well as I guide you. She is your responsibility.

-Haruto ..... Yes, that was the last letter before your father's death. As your father requested, Guren educated you very well, he was even like an older brother to you. Sometimes, you worry that he will slowly move away from you like your previous friends because you are too naughty because you have known each other for so long, Guren even knows what foods you like and what things you don't like. Even your frequent illnesses, He almost knows half of you. Even your fighting style
