That is not the point: the point is that Kizaru "forced" the G5 without even using Awakening, because G4 was not enough. If he won't have it, ok, then this is 100% Kizaru, but if he has awakening...
Kaido fought totally seriously against Luffy G4 bar for his last technique.
tbh, I am not saying Kizaru > Kaido. I just expected Kizaru to need Awakening to force Luffy to serious G5.
