Death March to the Parallel World Rhapsody

Ichirou Suzuki, a programmer in his late twenties, is overwhelmed by his job. Exhausted, he finally gets some rest, only to wake up in a fantasy world that seems cobbled together from the RPGs he’d been debugging. To his surprise, he looks younger now and goes by the name Satou-a handle he once used during game testing. Before he can make sense of his new surroundings, a horde of lizardmen attacks him. In self-defense, Satou unleashes a devastating spell, obliterating them all and skyrocketing his level to 310, maxing out his abilities. Stuck in this strange world with no way back, he decides to embrace his role as an overpowered adventurer and sets off to uncover its mysteries.
