An0n1m0u5e Sir you haven't heard of Re:Hamster.... your Idea had been done before and has been huge success too.... (though I need to point out that Re:Hamster is on 18+ side with lots of hardcore snu~snu~ and "Dark spear to the face"(The attack he uses in a fit of anger which results in some gory scenes.)
Sexual Content
Steeve was a weird guy, he hated his world, and proved it by killing hamsters in the funniest way, but bad luck for him he died in an equal stupid way.
And as he did, the hamster God who was bored reincarnated him as a hamster in the world his pantheon govern, the twist? He forgot to turn of the hero system, and so our protagonist is now a super hamster, who decided to follow the path of a demon lord and made a mess of this world in vengeance!
WARNING:
This story is about a EVIL protagonist so there's a lot of EVIL in there!
Also there's a lot of 'mature' scene so be wary of that!
WARNING TAG:
