If its just Kiku getting bodied, idk why that was is so hard to explain outside of a vague "Izo reacting to something shocking" statement.
I remain skeptical on this. I can see it happening, but I don't know why Izo would react this way since Kawamatsu was yeeted last chapter and nobody batted an eye. Maybe its brutal has fuck, idk. Just weird why it wouldn't have been explained from the beginning, if that's the case.
