[Crossover] [Leveling Up] [Villain Protagonist] [Behind the Scenes]
A heads-up: this is primarily a crossover novel, plain and simple.
He was an orphan with nothing, then suddenly transmigrated to a new world.
But even in this new world, he was still facing a deadly crisis.
At the very last moment, he awakened the ability to travel between worlds, setting off on a journey to gain power from other worlds. (The protagonist gradually turns evil. Don't read if that's not your thing.)
World order: Shakugan no Shana - Cyberpunk Apocalypse (main world) - Black Bullet - Cyberpunk Apocalypse (interlude) - King of Fighters Infinite (predecessor to MUGEN) - Cyberpunk Apocalypse (conclusion) - Ultraman Ginga... These are the worlds planned for now.
