Asahi Haruka.The occult research society receives a tip about a supposedly cursed girl named Haruka Asahi and Kotarou decides to investigate the urban legend. Shortly thereafter, odd things begin happening around Kotarou such as glass that mysteriously shatters. Kotarou soon discovers that similar things have happened to others connected to Haruka and those who have investigated the urban legend before. Undeterred, Kotarou goes to the orphanage where Haruka once lived, but Lucia is there waiting for him. Kotarou realizes that Lucia is actually Haruka, and Lucia explains that she has the power to poison anything by touch and to break glass at a distance. Although Lucia had unknowingly poisoned Kotarou earlier, he uses his Rewrite ability to immunize himself. Kotarou later learns from Lucia and a teacher, Touka Nishikujou, that they and Sizuru are members of an organization called Guardian whose aim is to protect the world. To do so, they are in pursuit of someone known as the Key who could determine the fate of the world's survival. There is also an opposing organization called Gaia that are likewise looking for the Key. In exchange for keeping this a secret, Kotarou asks Lucia to make him lunch while wearing a maid's uniform.
