The Crossbow team takes part in their first illegal battle, but nefarious forces are at work behind the scenes. If Sousuke doesn't play his cards right, this first battle could end up being his last.

Sousuke’s team struggles to escape, but the path to freedom is blocked by someone from Sagara’s past who seems to be able to predict their every move.

While enjoying considerable success fighting in the arena for Nami's team, Sousuke starts to grow accustomed to his new life in Namsac. But little things keep reminding him he came to this city with a specific purpose in mind.

Kaname, Sousuke, and the gang use summer break as an opportunity to visit the Narashino military festival, and during the annual AS competition, Sousuke helps give the underdog an advantage.

Sousuke makes his way to the city of Namsac, where people bet on fighting matches between decommissioned Arm Slaves. Thanks to a bit of serendipity, he meets a team owner named Nami at the arena just when she's looking for an AS operator.

The giant AS - Behemoth - is on the move, crushing Mao's M9 in only seconds! When Kurz attempts to engage the monstrosity, the situation looks bad - until a crusader appears in the sky!

Sousuke and Kaname work together to save Kyoko and everyone else at Jindai High, and they both reach a point where they must make difficult, fateful decisions. Tessa likewise tries to save as many of her people as possible as she abandons the island base.

Kaname is in a bad mood after seeing Tessa emerge from the bath. Unfortunately, even as Sousuke Sagara tries to explain that things aren’t what they seem, Tessa finds a way to make the situation worse.

The SRT team has its hands more than full trying to protect Merida Island from three rampaging Behemoths. Sousuke and Kaname attempt to deal with their own frantic situation, as Amalgam's Kurama drags the students of Jindai High School into the fray.

Sousuke suddenly decides to become Mizuki’s boyfriend! The cold, watchful eyes of Mizuki's friends settle firmly on Sagara - but it’s Kaname’s reaction he should be worrying about.

In Tokyo, Sousuke and Kaname flee from enemy agents in a desperate attempt to rendezvous with their allies. On Merida Island, Mithril struggles to respond to a fierce and demoralizing assault by Amalgam forces.

Kaname, Sousuke, and Kurz are out of options, so Sousuke suggests that Kaname should flee on her own. Not only does she refuse, she manages to save all three of them!

Amalgam decides it's time to get serious about its Mithril problem, and this means big challenges are on the horizon for Sousuke, Kaname, and Tessa. As enemies close in on all fronts, will they find ways to overcome those challenges?

Kaname’s plane gets hijacked by terrorists led by Gauron - who is supposed to by dead. Sousuke is frantically formulating a rescue plan when he feels the cold weight of a pistol pressed to his temple.

Siegfried’s monstrous minions are rampaging through the city. While Cecily and Aria bravely fight the beasts alongside the Knight Guards, the final battle between Luke and Siegfried begins.

Sousuke Sagara accepts his mission to protect Kaname with zeal - maybe a little too much zeal. His habit of threatening every suspicious-looking character in sight draws the wrath of Ms. Kagurazaka.
