Well, Akikan, why did you have to make a protagonist with a half-hearted character like this? If you want to make the protagonist evil, just do it, don't do it half-heartedly. (Sorry if my English is wrong, because I use Google Translate)
Why did he keep saying he can’t die? I mean there’re still many being in dxd world that can kill him easily right now, like ophis, great red, shiva, odin, indra, etc..
