I'm in a crossover anime world, and I've been transported to Hogwarts twice.

Waking up in a chaotic crossover anime world is confusing enough, but Genichi Hanyu’s reality comes with a bizarre double shift: every time he falls asleep, his consciousness is transported to the magical realm of Hogwarts. Two entirely different lives, yet neither offers any peace. To make matters worse, Gaia—the world’s counterforce—has an irritating habit of randomly fishing hazardous anomalies out of the World Ocean and dumping them straight into the daily anime setting. From the relentless T-virus and swarms of Kabane to bloodthirsty ghouls, Gastrea, and towering Titans, these threats care nothing for human survival. Left with no choice and armed with little more than his wizard’s wand, Genichi must moonlight as a magical custodian, cleaning up Gaia’s reckless cosmic messes before the everyday world collapses.
