KO One: The Myriad Worlds' Contract Holder

After transmigrating to the Ultimate World, Lin Yao becomes a transfer student at North Banana High School.

Awakening the Myriad Worlds Contract System, he can become infinitely stronger by making contracts with heroines?

On the KO Ranking, he keeps his strength hidden as he climbs to the top one step at a time, punching his way through South Banana and crushing KO One beneath his feet.

Across the myriad worlds, he makes contracts with Hinata, Nami, Rukia, Lucy...

He protects his own to the bitter end. Anyone who touches them dies.

"You touched one of my people? Ask my battle power index first!"

This is the story of an utterly self-serving, fiercely protective man who stirs up the myriad worlds, starting at North Banana.
