Strange, did you not read the spoilers where Luffy goes out of G5 and in his old aftereffect and Kizaru simply took a punch?
Did you miss the part where Kizaru is down on the floor from the attack and g5 ran out
Is that Kizaru beating g5?
I guess Doffy was able to beat g4 too since g4 ran out after he got wrecked baldy by it and was on the floor seeing heavens
Luffy going out of g5 or g4 =/= lost (got KOed by the opponent
Kaido didn't beat Ryuo G4 when g4 ran out at rooftop
He only beat G4 once at rooftop when drunk kaido koed adcoc g4.
Kaido didn't beat G5 when g5 ran out before his eyes even tho kaido was on his feet
So why would kizaru be given a W for doing nothing like what kaido even did?
