i think the agents probably gave him a dorm room, because if they didn’t i don’t know where he’d sleep… though that would make sense as to why he’s basically moved in with rei lol. he doesn’t seem super fond of the agents anyway, so being with rei is probably preferable, even if he’s just sleeping on the couch. if there’s a gap between when he left the facility and joined the agents, i wouldn’t be surprised if he just slept on the streets for a while. he seems stubborn enough to do it

i know mariyasu’s doodles aren’t technically canon, but there’s one (the one with the cockroach) where it looks like he’s hanging out in an apartment. so i like to think he gets his own place after knk
