I am thinking that Kohai might be town.
Say I were scum and I decide to recruit him last NP - I do so knowing that he counter-claimed and lynched a townie last DP. That moves him to the top of a lot of scum piles and makes him a big mislynch target. His claimed role can also fuel paranoia and make him an easier mislynch target once Casey flips without having to recruit him. Scum also had no idea his ability does not deactivate at lylo/mylo, which means town could just leave him alive and lynch him then were that the case (as it usually is). I don't think he's as attractive a recruitment target as people thing. From a scum perspective, it just means you get to take out a townie when your dude is lynched. Is that powerful? Yeah. Is it better than taking over a top-tier player who is widely townread? Personally, I'd take the latter route.
