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. When Nina finds herself in trouble, Layfon reveals the true extent of his power.

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. If he doesn’t join the fight, all could be lost.

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

Nina’s grueling training schedule causes her to fall ill. With their leader out of commission, Layfon and the rest of the 17th Platoon must depend on teamwork to defeat a powerful Contaminoid.

The 17th and 5th Platoons must work together to investigate a city left in ruins by Contaminoids. During the mission, Gorneo shocks Nina when he reveals information about Layfon’s secret past.

During a trip to a resort, Kalian can barely handle it when Layfon tries to teach Felli how to swim. The tension only grows when the sudden appearance of terrorists leads to a hostage crisis!

Hostilities grow between Sharnid and the members of his former Platoon. Later, Layfon’s investigation of a drug-dealing operation leads to a confrontation with a mysterious mercenary from Glendan.

Nina confronts Dinn about his Overload use, warning that the authorities might be catching on. Later, Kalian has a mission for Layfon, Nina, and Sharnid - and they’re going to be working with Haia.

During a competition, the Fallen One inside Dinn is captured by Haia, forcing Layfon to take action. It will be up to Dalsiena to find a way to separate Dinn from the spirit possessing him.

The 17th Platoon heads to training camp to prepare for their upcoming competition. Complications soon arise between Layfon and Mayshen - and just as they seem to be working it out, disaster strikes.

Nina decides to lead the charge in the competition against the 1st Platoon. Later, when something causes Zuellni to change course and head toward a group of Contaminoids, Layfon must join forces with Haia.

An encounter between Zuellni and Glendan seems inevitable, and Myath is still lingering in attack range. Just as tensions reach a boiling point, a new threat appears in the sky.

As Layfon and the others search desperately for the missing Nina, the 17th Platoon is caught in an ambush perpetrated by a villain who has been lurking very nearby.

When the Fallen One possesses Savalis, Layfon might not have the power to survive. Everything he holds dear is on the line - and the fate of Zuellni is in his hands.
