Leonkin
ohh so that the problem I don't have much idea's but how about he actively participate in all wars against slane or atleast in some till they were forced to try and use mind control world item but that was MC plan to get his hand on their world item and after defeating their strongest warrior he force slane to release all the captured Elfs slaves how about that for now and after that he get back Zasshi as she will still be a child and then use mind control item on strongest god kin to understand how they nurture so many strong god kins and you can also stat what he is doing to improve his country as an absolute monarchy
