It is a bingo request for the man who does honest vigilantism-- the Crawler!
Oh Koichi... this is where I'm going to start pissing people off isn't it.
I don't hate Koichi but...my favorite arcs of Vigilantes are the ones without him in them. And I don't think that's entirely the fault of the character. His dopiness is endearing, his quirk and it's versatility is interesting, and he works as an underdog shonen protagonist. But that's just the thing. He works as a standard shonen protagonist.
I do think Vigilantes is worth its read overall if you're a fan but it has the side effect nowadays that it highlights how much the main series breaks away from conventional shonen and superhero storytelling by...yknow...doing a more by-the-books story with secret identities, a tsudere love interest that doesn't do much, and a final fight that's just kind of a dick measuring contest of which one is refusing to die harder. It's good, in a general sense, but compared to the main series it feels like it should have been more and that mediocrity kinda extends to Koichi for me.
Plus he really feels like a character I would need to fight the rest of the fandom for calling dumb even though, yes he is very dumb and there's nothing wrong with that. Gives me...previous fandom flashbacks.. It's an association I shouldn't place on him but my brain does it without my permission.
All that being said I really hope he gets a cameo at some point or Vigilantes finally gets that anime every keeps making fake articles announcing. All you Crawler stans deserve it, I genuinely mean that. ❤️
