A Monster Hunter Becomes a Princess(2021)

Killer-jiman Gongjuro Sarabolkka Hae

I, a great monster killer, was about to plunge my knife into a vampire’s heart to avenge my parents’ death… when I woke up in a princess’s body instead! All I want is to return to my world so I can complete my revenge. But here I am, stuck in the body of a princess who is considered bad luck by the entire kingdom. Well, at least there’s one other man who got tossed here from another world, too. Hopefully, we can find a way back, or else I might be killed!
