I’m already overpowered, what changed?

What happens when you are no longer human? Save the world.. or be the monster, you were made to be? Were you ever truly human?, maybe something more, but in the end, this is the power you asked for, so why question it now, just be, whatever it is you want to be, in this life. Harem so do with that as you will, there are only 6 women so.. Btw I made the Mc stronger.
