Oh, Koichi. You were so close.
It was bound to happen; the kindhearted Koichi, unable to finish off the evil No. 6. It still sucks to see it though. So, does this mean Koichi will overcome his empathy and beat the living snot out of No. 6? I doubt it. That’s not The Crawler. Sure, he fights, but he’s not a mega violent person. I think Koichi’s friends and allies will help him take down No. 6. That plus No. 6’s decent into madness and eagerness to destroy Koichi will ultimately be his undoing.
Loving the hero/villain relationship between Crawler and No. 6. Both are speedsters, one modeling himself after All Might. The other, born from All For One’s evil ambitions. The two even look like similar to their morality adjacent mentors (Koichi’s costume and No. 6’s no-face). Not to mention, learning No. 6 modelled his Rokuro Nomura face after Koichi’s! It’s so fascinating watching a glorified sociopath wanting to become a hero go head-to-head against an overly sympathetic vigilante. This alone makes this arc one of my favorites of the entire series.
