Muteba is my winner in all this just based off the strength of being pragmatic. I'm glad he didn't get turned into a "I'VE NEVER FELT THIS BEFORE! I GOTTA SUMMON THE GUTS FROM DEEP IN MY BOWELS TO WIN THIS! I CAN'T AFFORD TO LOSE!!!!" type character.
Though whoever called Wakatsuki tightening his neck muscles to "catch" Muteba's hand... I love you and I hate you.
OF COURSE he noticed he wasn't blind anymore and of course he noticed he was going for the neck ... I'm glad Muteba forfeit, with a cheating character like that it really wasn't worth it, his explanation from previous chapter was enough.
