When Jonny takes a job at the mysterious Supra Corporation, all he hopes for is a decent paycheck and some benefits.

He never expected to become an Overseer, a job whose responsibilities entail managing a slew of other universes like some kind of interdimensional gamemaster.

Defending against an elf rebellion, domesticating wild dragons, preventing kings from achieving godhood — all in a day’s work. With the help of Supra Corporation’s proprietary System imposed on every world it's tasked with managing, Jonny helps maintain order throughout the multiverse.

Realm Manager features an OP MC with access to several realms he manipulates both remotely as well as on the ground, getting into scraps and misadventures that he resolves with the help of a growing roster of transdimensional friends.

This one's not lewd, just a head's up. No harem here.
