A hitman and cannibal who's basically Rizumu's brother in all but name. Izumu exists in this complicated dynamic with Zerozaki Hitoshiki—they're rivals, sure, but there's definitely a friendship underneath it all. The relationship's weirdly central to who he is, honestly. Fans often note the tension between them feels genuine rather than forced, which is part of what makes their interactions so compelling to watch.
