My prediction; (A wild guess, have not read any raws. But just in case I'll put it in spoiler tags...)
Dad has remarried and somehow got their SO to pay the debts. That new wife will have a daughter that comes along. In a twist the father gambles their fortune away in a casino, they again lose the apartment and dad goes away to pay the debt again, while the rest of them find themselves staying with Chiriko again...
