Him totally losing it and seeing Niko everywhere is neat, and it explains neatly why Rei and his owner weren't attacked, but I'm not sure why he would try to save Kazzie so hard. I don't recall, has Kiryu even acknowledged him before?
@Demomanowar
Well, he had a good impression of Kazzy: https://mangadex.org/chapter/4042/1
In his mind, a good person + Ohma's friend is a very solid reason
That's too bad, for a moment, I thought he could be saved... After all, he wanted to save the girls too.
Also thanks Hokuto No Gun, being able to drink my morning coffee each day with a new chapter is a blessing
@Beastkun I know I'm hella late, but the author could have had Muteba beat Wakatsuki after losing an arm, then have him force Tomoko to substitute him out for someone so his career as a mercenary wouldn't be in jeopardy from more injuries. That someone could be Kiryu, setting him and Ohma up for a semi-finals fight.
I do like how this story has played out though, so those are just pointless what-ifs.
