KO One: I Smash Through the KO Rankings with a Ruler from the Start

Huangfu Yixin transmigrates to the world of KO One, becoming Wang D-Dong's neighbor and Chinese teacher.

He seems gentle and refined, but secretly wields the power of Death. One swing of his ruler, and all beings are equal.

Wang D-Dong: “Brother Yixin! Don't come any closer...”

Huangfu Yixin (smiling): “Your teacher will be gentle...”

Wang Arthur (with both hands swollen from beatings): “Teacher, your teaching methods are... quite distinctive.”

Rex (pinned to the wall by Six Rods of Light): “I was wrong! I really was!”

Black Dragon (bruised and battered): “Trouble! Let's get out of here!”

Tian Xin (blushing): “Yixin, the way you teach problems... you're even cooler than when you fight.”

And when he is forced to enter the space-time battlefield and face the Demon Lord Diabolo...

Senbonzakura scatters,

“You call this a Battle Power Index?”

“No, this is Bankai.”

You know, Lord of the Spirit World?

(Female lead: Tian Xin. Whether she's the only one is another matter... I'll write whatever comes to me...)
