While his age is not actually stated, Chuuzenji is supposed to be in his early to mid 30s (and so are his 3 buddies).
Mouryou no Hako has anime adaptation, but I'd sooner recommend manga.

Chuuzenji Akihiko got one figure, but it's based on the prettified design from Mouryo no hako anime and looks like cheap shit. It would be great if he got something like pic related, but that's a never ever, he is popular, but nowhere near that popular.
