It is natural to pay back debts, but some people think that owing money makes them the boss.

Toosaka Rin: "Why should I pay back the money my father owes you? I have no money anymore."

Gabriel: "I used all the money to buy games, go ask the game company for it."

Sandwich: "Money? I don't have it anyway! If you want money, go find Medusa, she's my guarantor."

Chen Lin: "Hehe... If you don't pay me back, I'll come to your house."

Jibril: "Guhehe... Come here"
