I'm still liking this manga for what it is, it gets ridiculous sometimes yeah but I'm enjoying the fights and that's why I'm here for, I'm not here for the story, I'm here for the fights.
And yeah, Misasa's foot was probably outside the light circle or whatever in page 12 of Ch. 80 so I won't be surprised if he gets disqualified in the next chapter, he either gets disqualified or the match will end up as a draw or something.
