Review Detail of Upty_Dupty in Sin System: Demonic Harem After Reincarnation

Like this novel. I've read a lot of r-18 novels with villain mc but it's one of the best. Mc doesn't care about others. The only thing he wants is to live for the fullest. So unlike other novels he is focused on his dungeon and women. Also I like that mc doesn't care about women's races. For example I've never read about seggs with spider or garpies
