The author knows how to write, but there is no plot development. Day one: I am an ordinary person, day two: I became stronger than the average devil. Day three: digimon. Day four: a dungeon to rock me. Day five: I'm going to go to another universe ..... Sorry, what? And where is the development of characters, where are the events of the Dxd universe. Where is anything? If you weren't going to develop the DxD universe, then why did you mention this universe at all? Write a fanfic about Killer Reborn if you want. No, I'm not against traveling to other universes, but is this jammed into the main universe? Even his original world (Earth) was much better developed
