Global: Fusing with Kaido, I Changed Class to... Teacher?!

In a world where everyone changes class, Kaifeng somehow became the world's only member of a unique class: the Short-Tempered Teacher.

Want to learn something? Sure!

Figure it out from Thunder Bagua!

One swing of the club, and there's nothing you can't learn!

First, one swing helps the school's campus belle, who has no class, change into one. Another swing teaches her to awaken an ability. Still not strong enough? Then another swing teaches her Advanced Conqueror's Haki.

Going into a dungeon? The students can form a party, and I'll supervise.

As long as they get stronger, I'm happy.

“Why are all the students Teacher Kai trains masochists?”

“Exactly! Every time they come out covered in injuries, they still say it felt great.”

“But Teacher Kai really is incredible. The world's ten strongest people are all his students!”

“Do you know how strong the short-tempered Teacher Kai himself is?”

“His students improve so quickly, but not one of them has graduated. What's going on?”
