Overlord: King of Adventure

I transmigrated into the world of Overlord.

Well, I've already transmigrated, so I might as well make my mark and carve out a legendary life for myself in this world!

I thought I would just trade wits with Ainz while becoming the greatest adventurer.

But then I found out that other anime characters had transmigrated into this Overlord world too. What? Could this be the butterfly effect?
