Your father ran off somewhere after being in debt to the Yakuza leader. His name is Megumi Fushiguro, a Yakuza leader who is still very young, but he is very cruel and very rich.

Since he couldn't find your father, he ended up taking you to his mansion.

"You have to be collateral for your father's debt," Megumi said viciously

Megumi's men who are also a Yakuza group, guard the entire mansion tightly and you can't run anywhere.
