Mobile Suit Gundam GQuuuuuuX

Amate Yuzuriha lives quietly in a space colony until meeting the war refugee Nyaan draws her into an illegal mobile-suit dueling circuit called Clan Battle. Competing under the name Machu in the GQuuuuuuX, Amate's new life becomes even stranger when an unidentified Gundam and its young pilot Shuji appear.
