Agate is a mysterious, happy-go-lucky boy who has just been enrolled at Cluster E.A., a prestigious academy. On the train ride to Cluster E.A., the train gets caught between a plane battle between Chalce and the military. Agate intervenes to help Chalce and triggers a strange power that pulls the two away from battle.

Agate manages to find pieces of his broken plane at the junkyard and finds a way to get to Cluster E.A. with the help of a man he saved earlier. At the academy, he befriends a young boy named Fon, a victim of the military students' bullying. The military school has occupied Cluster E.A. in order to participate in a rival-like competition to determine the schools' reputation; because of the high expectations of the military school needing to win, the military students attempt to kill Beryl. However, Beryl narrowly survives the accident and makes Fon promise not to tell anyone. Despite Beryl's injury, Agate miraculously heals Beryl's arm during the fencing competition, leading him to victory.

Vespia, a man from the military, visits Professor Hematite and explains that his friend Chalce has died. He also reveals that he is conducting an investigation as to who helped Chalce during the battle. Hematite researches and discovers that only Agate and Beryl were present at the time. Vespia immediately picks Beryl to blame, knowing that this would ruin Beryl's prestigious reputation. When he confronts Beryl and Hematite, Agate's power reveals that Vespia was the one who murdered Chalce, and in rage, defeats all of Vespia's reinforcements. Unfortunately, Agate is tossed into the river shortly after this happens.

Hematite leaves the academy, troubled with thoughts about Chalce's rebellion against the military. When he returns home, he discovers that his father has gone to one of the old plants used to produce artificial soldiers despite the ban to meet Ludwig from the religious sect. Ludwig explains that many of the soldiers were killed when there was too much emotional stress from the artificial soldiers, and one boy who saw everything escaped from his pod. Meanwhile, Chrome and his group fight against the military in revenge for killing Chalce. When Chrome tries to take down Ludwig, Hematite interferes and Chrome, recognizing who he is, pauses and leaves. Ludwig reveals that because Chalce believed artificial soldiers could develop ethics, he implanted memories and gave Chrome personal morals.

Agate wakes up and saves an old man from being crushed by a chimney. The old man is grateful for his help and treats him to dinner despite that he is broke. When the restaurant holds the old man captive for being unable to pay his bills, Agate goes to casinos to help raise money for him.
