After arriving at Zuellni Academic City, mysterious Layfon makes quite an impression - and is quickly forced into joining the 17th Platoon of the Military Arts Department.

After Layfon meets the 17th Platoon, he joins them for a game of capture the flag against the 16th Platoon.

After intruders attempt to steal Zuellni's electronic spirit, a painful incident from Nina's past is revealed, shedding light on her motivation to grow stronger.

Though she's reluctant to rely on her powers, Felli may be forced to use her special abilities when she and her friends fall under attack at an abandoned research lab.

Zuellni falls into a massive nest of Contaminoids; as Nina leads the Military Arts students into battle, Layfon stays behind, convinced it's a suicide mission.

Layfon accepts a temporary spot within the ranks of the Municipal Police; his first task: stop a group of undercover espionage agents.
