The Knight Intruder of a Certain Jesmon

He arrives in Runeterra, the land of Valoran. As an abnormal sort of being, being born in Ionia, the First Lands, doesn't seem like much of a problem.

Ionia's survival guide: Since this is the realm of the First Lands, be sure to remember that if you accidentally step into some abnormal area, that's normal too. And I'm just an ordinary Digimon here.

On top of that, he has a reasonably useful System, built around the League of Legends universe, that lets him travel between different worlds.

The Warring States arc of Demon Slayer is tentative. The Familiar of Zero is tentative. Negima! is tentative...
