Synopsis
Human beings advance into space and frost. It is the power of "magic" that has helped us overcome many difficulties while facing them. Aristotle is an educational institution that guides magical talents that only a small number of women usually have and develops human resources who are responsible for space development.

Sagiri Seina, who was dying after being attacked by an alien phantom beast in the orbital elevator heading there, meets the space magician Gear Revolva, who is known as a hero. Only one of Gear, who himself was fatally injured in the battle, can be magically saved ── As a result, Rei, who survived by arousing the power of Gear, awakens as the ninth male space magician in history. However, that meant that he had a new destiny of being a "survivor at the expense of a hero."
