Mobile Suit Gundam GQuuuuuuX

Amate Yuzuriha, a high school student, lives in a space colony where she's met Nyaan, a war refugee. Their acquaintance leads to Amate participating in Clan Battle, an underground mobile suit dueling sport. She uses the alias "Machu" and competes using a machine known as the GQuuuuuuX. The appearance of an unidentified Gundam mobile suit, being pursued by both the space force and police, introduces a new variable into her life, along with its pilot, Shuji.
