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.
They're the unforgettable...
...إنهما ثنائيّ الشّيطان
Ich werde niemals vergessen, …
Son la inolvidable…
Son la inolvidable…
et qui ne pourront jamais oublier…
Loro sono l'indimenticabile...
Uma coisa que jamais dava para esquecer.
Игра с ними остаётся в памяти навсегда…
