Hitsugaya (Adult form) , Kurosaki starts in Bankai

-Everyone starts in ShiKai except the last round

How far does He go?

Stops at 6. Stops at 8 for sure

Stops at 5, if not gets godstomped at 6.

Might stop at 5 or 8, might clear as well.

Could stop at Shinji depending on how quick he is to adapt to his shikai. Shinji who isn't messing around is very scary and his shikai is perfect to deal with 1 brawler with no hax.

If not, hard stops at 6. Komamura is probably weaker than Ishin and Rukia gets blitzed before she gets bankai off. Unohana can take him in a straight up fight.
