As the name TenSura And Beyond suggests the MC will not be restricted to TenSura he will travel to other worlds.

Also I have made a another level of skills beyond Origin Skills.

So if Ultimate Skills are reaching the Ultimate principles of the world then Origin Skills are the Origin of those principles. For example, the Magicule Breeder Reactor is the origin of Magicules and Stardust, the Akashic Records are the Origin of skills, and Turn Null is the Origin of Nothingness and Nullity.

After Origin is Transcendence, were you basically transcend the world and their are transcendent resist skills. For example Fire Transcendence and so on. This is how the MC travel to other worlds.

Some worlds he may travel to:

Naruto

Bleach One Piece

Dragon Ball

My Hero Academia

Jujustu Kaisen

Re: Zero

One Punch Man

Black Clover

Tell me any good worlds that have lots of powers or pink hair waifus, because I don't watch that many animes.
