Return The Demon King of Gluttony

One day, a man from Earth died after being hit by a truck, and like the typical isekai stories, he was reincarnated not as a human but as a demon in a world that was not Earth or a similar world, but a demon world: Gehenna. With his intelligence combined with his Predator ability, the man, now a demon named Belial, became one of the kings in Gehenna and earned the title 'Demon King of Gluttony.' Unsatisfied with being just a Demon King, Belial eventually tried to challenge the ruler and creator of Gehenna, the Demon God Jainko. Due to his arrogant actions, Belial met his second death. However, his fate didn't end there. With the abilities he acquired from devouring the Ruler of Souls, Arima, Belial transferred his soul into the body of a young man in a fantasy world of swords and magic. What will this man do now? ================== I changed the cover, because I think the current one is cooler. And by the way, the image is not mine, so to the owner of this image, please comment and I will immediately apologize and ask for permission to use it. Even so, I made the cover myself, only the pictures belong to someone else. And if my English isn't good or bad, I'm sorry, because I can't speak English enough. Greetings [Author].
