My life in the underworld begins at the Takayanagi family!

A family-sized bucket of food.
Liu Changsheng transmigrates to a crossover anime world (mainly the inner world), gains the blessing of a loan system, and becomes the head of the Takayanagi family.
Akizuki Airi: Why is it that the one who paid off the debt isn't me, but my mother? I could do that too!
Kaoru Takayanagi: Should I call you older brother or father?
Rika Adachi: Uncle, even though I've become an idol, I belong to you too.
Rinka Ooki: Kill her, and I'll offer up my mother.
There are also Katsura Kotonoha, Saionji Sekai, Amamiya Misako, and others for you to conquer yourself!
