Semi final? does that mean Haruo was sent to the loser's bracket? Or is this the grand finals and Oono trying to go for the reset
It seems that rather than a true "loser's bracket", Oono was entered into a "second chance bracket" (and already finished/won that)
They're in a single-elimination tournament, but people who lost in the group stage got a second chance to enter the "real" single-elim tournament.
Edit: anyway, this chapter was hype as fuck. I think Haruo is legitimately going to win round 2, his first legitimate round victory against her ever (her broken controller didn't count lol), but I have no idea how round 3 is going to go.
