Irie Izumi has been summoned to another world to fulfill his heroic destiny! He quickly meets and forms a party with Level 20 white mage Shina, who falls in love with him at first sight. When Irie succeeds in his quest, he will be transported home--but Shina isn't about to let her "Lord Hero" get away so easily! What's a girl to do, except dress so lewdly that even a great hero of destiny can't pay attention to the battles before him and can't level up!
