any manga where the mc gets revenge on someone and goes from weak to strong? preferably male MCs

I can't really tell you anything without spoiling it,but trust me it gets real good
i have a feeling that at the end, MC won’t go back to original world but stay in this dimension
Same.
So do I! I can’t see him leaving everything behind tbh but the only way I see that happening is if they found out that the MC is the actual original soul (or at least part of the soul) of the Demon King. That way he retains his kinder side while possessing the traits and memories of the original King
