Synopsis

The main character won't be reincarnated, but an irregularity in all the worlds she visits. She doesn't need to absorb something or someone to use that ability, just to see them (like a ditto from Pokémon but with her own details and can add some parts from other copies). She won't have too much common sense or conversational skills at the beginning but she will learn at some point.

Mc abilities (original ones): copy, immortal, eidetic memory, ageless, nigh un kill able, extreme learning, multiverse travel, and human transformation.
