On her way to class, Luuta slips on the wet floor and crashes into a new male student. As he goes on his way, he leaves behind an iridescent bottle which she picks up. Next a shopping center is rocked by an unexpected earthquake and in the midst, Luuta hears a loud roar. She saw a fairy lady and a knight running to the sound and vanishing in mid-air. As she continues looking, Luuta steps into an invisible barrier and finds the boy wielding a sword as he battles a monster. She learns that he is a young knight but isn’t experienced enough to fight on his own. He needs assistance.
