sfw poe headcanons because im in a mood rn:
he's surprisingly good at makeup (he frequently uses concealer for obvious reasons). if you asked him to do yours he would be over the MOON
he has a comfort toy from his childhood hidden away somewhere in his house. he doesn't sleep with it anymore but he refuses to get rid of it
he's good at badminton. don't ask.
every single thing he handwrites is in cursive and most people can't read it
he's pretty good at drawing so sometimes he does rough sketches alongside his drafts. these never see the light of day though
he prefers to do things alone because he doesn't like the ways other people do them. he's a bit of a control freak when it comes to group activities
he can't stand black coffee- doesn't matter how bitter it is, it MUST have milk in it or he won't drink it
he gets along well with Kyouka and lets her hold Karl sometimes
he doesn't really like technology. aside from using his phone to contact Ranpo he essentially lives in an Amish paradise. he carries a lantern around when it's dark 💀
