(I've not read the web novel or light novel that this is based on. )

Reincarnation, Remember, Revenge. with a hint... I mean a bowl of S and M and this is what you get. [not sorry for the crappy alliteration]

I wish we could have seen a bit more of Keare's journey from innocence to corrupt but hopefully more flashbacks will happen in later chapters. EDIT: Still not as much as I hoped there would be.

As you would imagine being exploited (and that's just a euphemism) till the very end would do some serious damage to the mind.

However, so far there does not seem to be a character that can be considered as a 'rival' or someone of equal power to oppose Keare which may become a problem - action or any danger becoming negligible because of Keare's OP-ness and knowledge of his world's future.

PS - all sex scenes are skipped. :^)
