KO One: What?! I Summoned Cao Yanbing from the Start?

Lin Yu transmigrates into the KO universe and awakens a Containment System. Characters from the Myriad Worlds will descend upon the Ultimate series' world, and Lin Yu must contain them. The more he contains, the stronger he becomes! But containment has a prerequisite: to contain a character, he must change certain events in the twelve time-space dimensions. Lin Yu can make these changes by stepping in and offering guidance, creating the System, assigning missions, or other means!

So Wang Dong, Wang Arthur, Ding Xiaoyu, and the others notice mysterious figures appearing around them one after another!

A man named Cao Yanbing joins KO One. His Guardian Spirits shock everyone, then he mysteriously vanishes!

A man named Jerome, codenamed Joker, joins KO One, foils Rex's plan, and plants bombs everywhere, terrifying everyone before mysteriously vanishing!

And another...

All kinds of mysterious figures appear around them, carry out some task, then mysteriously disappear, as if an invisible hand is controlling everything from the darkness! Wang Dong and the others frantically search for answers!

Until one day, the Demon Realm descends, and a being named Lin Yu appears in the world, leading the mysteriously vanished figures. The twelve time-space dimensions are shaken!
