No, Ryuuzaki didn't have a wife and daughter
No, Misumi was married for a half year, but then his wife died, and I think he was married to Amou's mother, since they talk about going to visit his mother's grave..
I think Ryuuzaki's woman is the woman whom we have seen before. I mean besides her there is only one other female, Doumeki's sister, in the story so far (unless if you count the random naked women)..
Oh. So I'm humbling the characters -.- who's who and who's not. （￣へ￣）
*scrambling
Isnt ryuuzaki had divorced wife in order to protect her, and about their daughter.. I dont really remember, anyone read something like that here?
