Osomatsu-san is a very meta show that does a lot of parodies. By default I'm going to just ignore this and say no other in-game characters or their worlds will remind him of any fictional canons he knows, but if for some reason you actually want him to fourthwall your character to some extent, feel free to let me know here.

CONVERSELY, since he is completely aware that he is an anime character, if your character would reasonably be familiar with either of the older versions of his canon — the 1960s manga and anime or the 1988 anime — I'm fine with them bringing that up (he'll just try to play it off while inwardly panicking, which is hilarious).

His canon is also just kind of offensive in various ways; please let me know if you want me to avoid tagging you in one-on-one threads now or later after you've seen him action.
