That... yeah that sounds about right, tbh. And some kind of outreach or volunteering for kid sports teams and other miscellanea really suits him.

Also it's funny because both Kiryu and Majima look a little bit like they'd fit right in with the coach of the team Koushuu and Eijun play for in canon.

The fact that it's got realistic, actual factual things is just kind of the cherry on top of the crazy sundae. And the mahjong is the sprinkles.
