The story starts with the protagonist Yuuto Kazama (14 years old) transferring into a new, prestigious junior high school after living in the countryside for a long time. Even though he is the school's new star pitcher, he is in fact an orphan from a junior high school baseball team whose members died in a traffic accident. Approximately one month prior to his transfer, Yuuto and his two closest friends were also involved in a traffic accident. Both of his friends died, but a girl who had been in critical condition at the hospital miraculously woke up after Yuuto began to pray for her recovery. From that time, Yuuto decided that he should not regret his past any longer and made himself a promise: he would devote himself to baseball, in order to never forget his two deceased friends, to not regret the past ever again, and above all, in order to have his two deceased friends appear in front of him once more. The story mainly concerns Yuuto and his relationships with the new friends he meets at his new school.
