The Interdimensional Crossover

Eighteen-year-old [Alex Raid] accidentally acquires omnipotence, omniscience, and omnipresence – the power to create and destroy universes, manipulate reality, and rewrite existence itself.  Initially awestruck, he conceives a unique application of his newfound abilities: a crossover story featuring his favorite anime characters, pitting them against each other in epic battles and intricate narratives within a universe of his own creation.
