Yeah, one thing I like about this manga is that it didn't go crazy with the power levels and that groups that would be relegated to fodder (Like the referees and even the police with their Private Funeral Division) are still very much a threat to protagonists and antagonists alikeI'm really glad no referee has shown to be a push over. 350 chapters later and they're just as menacing
A lot of manga do so much power scaling that groups like referees become weak in relation to the story
