Code 8

Shigo’s father passed away a few years ago on a mission given by Vesteria, and Shigo grows up with a deep resentment towards Vesterias and the people who work for them. He becomes a rebellious teenager, getting into fights and causing trouble.

One day, while Shigo is causing a disturbance in the city, he is caught by a member of Vesterias named Ayumi. Ayumi is a skilled pilot of a mech and has a kind heart, despite her duty to uphold the rules of Vesterias. She takes Shigo under her wing and begins to teach him about the importance of their mission to protect the city and its people.
