Aoi Umi no Tristia

Young inventor Nanoca Flanka is busy helping the seaside city of Tristia recover when her former academy rival, Panavia Tornado, arrives with a challenge. Determined to prove her superiority, Panavia pushes their competition into a newly organized golem tournament.

Both inventors pit their creations against one another, but the machines’ power soon exceeds the bounds of a friendly contest. When a golem runs out of control, its unstable reactor threatens the entire city. Nanoca and her companions must stop it before the rivalry destroys the very place her inventions were meant to restore.
