KO One: The Plot's Gone Off the Rails? I'm the Fated Ultimate Villain

Over a hundred thousand years ago.

A figure descended into the Demon Realm of KO One's world.

Thanks to his extraordinary potential, he became the Demon Realm's one and only Supreme in a short time.

His terrifying strength earned him the title of Demon God from the twelve spacetime realms!

Yet one day, this mighty being suddenly vanished without a trace.

Rumor had it that he fought the Flame Messenger for seven days and seven nights, and both ultimately perished on the spot.

No one knew whether it was true...

…

Over a hundred thousand years later.

In the Golden Spacetime, at Balie High School.

The seemingly frail young man before them was named Bai Ze, the current substitute teacher of KO One and an utterly ordinary person.

At least, that's what everyone had thought.

Then the Demon Realm launched a full-scale invasion of the twelve spacetime realms, and Black Dragon perfectly fused with the Heavenly Demon Combination during the battle between good and evil in the Golden Spacetime.

The frail figure who slowly walked out of the classroom subdued the entire Demon Realm army with one hand and suppressed Black Dragon with the other.

Only then did people remember the legend from over a hundred thousand years ago...
