Despite his descent into adulthood, Dave Kowalski remains an avid player of the popular monster-raising game, metaverse monsters. Unfortunately, while engrossed in his game, he wasn't looking where he was walking, and stepped straight into a portal to another world. Rendered deaf and blind by the after-effects of dimensional travel, Dave lands in this new world, with only the limited mercy of the local goddess giving him any chance at survival. His new home may be a dead, post-apocalyptic wasteland, populated by zombies and deadly monsters; he may be crippled and alone, but Dave has one thing going for him. He chose the summoner class.
