While watching Blast of Tempest, Naihe went to the bathroom and somehow transmigrated into the world of Dororo.
Uh...
He has the Trees of Genesis and Exodus, two divine trees, built into his System. By offering objects of civilization to the trees, he can gain magical powers.
Armed with an almost invincible System, Naihe begins his mission to travel between worlds and exterminate the Black Death Bugs.
Heh heh.
And since he's already invincible, of course he won't let any of the tragedies or frustrating plot developments that happened before happen again.
Besides...
He'll take every beautiful woman in this world for himself, without leaving a single one out.
He won't mind having more, either. After all, he has a collapsible fortress with him. Maybe he'll stop once all the houses inside are full.
At present, the number of vacant rooms in the fortress is 108,700...
I'm writing the Dororo arc now. The next world is undecided...
