SOSUKE SAGARA
SS
The Second Raid begins with Sosuke trying to maintain the impossible balance he built in the first series: Mithril soldier, Jindai student and Kaname's hidden bodyguard all at once. That balance collapses when Mithril orders him to stop protecting Kaname and return to operations full time. Sosuke obeys, but the decision leaves him distracted, angry and increasingly unable to use the Arbalest's Lambda Driver properly. Clouseau's criticism hits because it exposes a problem Sosuke cannot solve with more training: he does not trust the machine, the order or himself. His disappearance also hurts Kaname in a way he failed to anticipate. The Hong Kong crisis forces Sosuke to decide what he is fighting for rather than simply waiting for another superior to define the mission.

In The Second Raid, Sousuke suffers a total psychological collapse when Mithril reassigns him away from Kaname Chidori’s security detail in Tokyo. Struggling to reconcile his identity as a cold mercenary with his desire to protect Kaname, his internal hesitation causes the Arbalest's Lambda Driver to repeatedly fail in mid-combat.
The Breakdown
The Lambda Driver does not respond to military discipline or doubt—it responds to absolute emotional conviction. When Sousuke lost his sense of purpose, the Arbalest became an unresponsive 10-ton metal paperweight, leading to his brutal defeat against Amalgam's Venom units.
Because the Arbalest is a prototype frame retrofitted with a Lambda Driver, activating the system generates extreme internal thermal stress. The unit must open its shoulder and back radiator cooling fins to vent superheated steam. Sustained use past 200 seconds risks total mechanical meltdown.
