In sports manga the good guys usually lose their first match against their arch rival, so a Kiyosumi loss wouldn't bother me too much ... theoretically. Practically any sort of rematch wouldn't happen for another ... dunno ... four-five YEARS irl and that's just too friggin' long ^^; Surely the manga isn't going to continue to just go on forever either ... I mean, it's friggin' mahjong. At some point the Japanese are going to get bored with the cheap fanservice, surely? And what then? Nothing ever gets resolved, probably ...
