Taro Yamada gave up on baseball and enrolls in a high school with no baseball team. But that's where he finds the strongest battery, Haruka Kiyomine and Kei Kaname. Why would they be here? Besides, Kei has amnesia and forgot about baseball.
The demon that only appears 
in front of Kaname Kei.
.الشيطان الذي يظهر أمام كانامي كي فقط
Nur im Angesicht von Kaname Kei
Celui qui n’apparaît
qu’en face de Kei Kaname,
È solo davanti a Kei Kaname che fa la sua comparsa lui.
É algo que só dá para ver quando
ele está de frente para Kei Kaname.
