Final Fantasy: Unlimited

Ai and Yu get into an argument and Ai is accidentally thrown from the sub. She meets up with a boy named Clear that wears flying water. He claims he cannot be touched or he could break them. Kaze comes along to protect them from monsters sent by Earl to capture Clear. Kaze says that Clear is dangerous, but Ai doesn't care. The monsters return and Kaze can't beat them because his Magun won't move. Clear tries to save Ai and she accidentally pulls his glove off. He destroys the entire cube as Kaze saves Ai and the ship barely escapes.
