The story development is refreshing and has a good tempo. Whether it's a dream or reality, one day after school, Jinnai Homura, a short-tempered brawler, is suddenly attacked by a mysterious monster. Then a mysterious young girl, Mina, appears who calls herself ``Warawa is the princess of the emperor of the underworld''...?
