Ten years after being transported to another world, what once felt like an exciting fantasy dream had long since become reality. A decade was more than enough time for the illusion to fade. After countless failed attempts to find a way back home, Wasa Tooru finally gives up on returning to Japan. Just as he accepts his fate in this parallel world, an unexpected opportunity appears. He receives a job offer to become the bodyguard of mysterious twins—two individuals who possess rare knowledge of Earth. Their connection to his original world may be the key to new answers, and perhaps, a new purpose.
