Possessed with an Evil Spirit (Male Reader X KLK X JJBA X HDXD X AGK Harem!)

I'm just a normal guy, that's what everyone says, so why do I have this evil spirit following me everywhere? Well, not only that, but I also have to deal with evil empires, demons, aliens, and did I also mention vampires? No? Well fine, I guess vampires too! But I guess having a bunch of hot girls with me is the better part of it! Well, this is my life now.
