After becoming the Lord of Nightmares, a Demon Lord in Diablo, Mo E began an endless journey and embarked on a path of unrestrained alterations to the worlds he visited.
His first stop was Sword Art Online. Under Mo E's guidance, Kirigaya Kazuto became the Stand user of [Star Platinum]. He went on to defeat Lelouch, [The World] Izayoi Sakuya, the vampire Kayaba Akihiko, and others, then kindled his divine fire, devoured the world, and became a new god.
His second stop was My Hero Academia. There, Mo E is taking a leisurely vacation while running a bakery called [Dio's Bakery].
PS1: Complete.
The Sword Art Online arc wasn't written very well, so you can skip straight to the My Hero Academia arc without affecting the plot.
PS2: I thought it over, and since some readers have asked about a reader group, I'll make one.
But based on my subscription numbers, there may only be a single-digit number of members. I hope you won't mind.
