Once upon a villain

If one day you woke up and found that being a moral person had become a difficult feat, that not committing horrible crimes was close to torturing yourself and that everyone read into your actions so that your intentions would never be believed to be good, if all that were to suddenly become your reality... Would you still try to be “a decent person”? Tzochjabe is a world full of monsters, demons and magic. When a young boy gets reincarnated in this world, he soon realizes he forgot all about his old self, but still remembers earth itself. Not only that, but his current life is that of Najiral, the demon lord's son! As only successor he becomes the head of the family. Najiral's life brings three companions to trust to the table, Najiral's body brings the perfect conditions to be an evil ruler, the new soul brings knowledge unknown to this world. Maybe he will actually not fail miserably, then. How hard can a villainous life of world domination be, after all?
