Review Detail of OneLovedBySpirits in Transgmigrating as a Succubus, Becoming a Livestreamer in Hell

I am confused... Before transmigration he was a male named Roy. He still calms himself Roy indicating he sees himself as a male but in intro it says he reincarnated as a Succubus - which is a female demon if great beauty and possess a great power over Charm and Illusions. He should be an Incubi - which is a male version of Succubus and it also has a power over Dreams. I just hope that he isn't a case where he has a male mined & female body. Dunno anything about the book, so after I read it I might change my mind and I'll change the rating.
