Two geniuses who made a name for themselves in the middle school baseball world but had distanced themselves from baseball have serendipitously come together at an obsecure public high school in Tokyo. Kiyomine Haruka, a pitcher with a flawless, powerful arm. His battery partner, the shrewd catcher known as the 'General', Kaname Kei (who's currently a complete amateur due to memory loss!). And then there are those who once fell in defeat to these two... Their paths have crossed once more, and now their high school baseball story begins anew, springing into action!
