Living in a gamelike fantasy world, Satou Suzuki is in no hurry to get back to his "death march" at home. He's content to take in the sights of Seiryuu City, go to a play with his friend Zena, and take care of the five girls in his party. After he discovers one of them was summoned from Japan like him, though, he prepares for a journey to learn more--until another friend is kidnapped by an evil sorcerer!
