Yasu

Despite holding the official title of Chief Combat Member within Zvezda, Yasu sits firmly at the bottom of the organizational hierarchy. His obsessive attachment to cigarettes routinely overrides his sense of duty, leading him to stir up chaos—or even betray his own comrades—in pursuit of a smoke or simple self-preservation. His antics never go unpunished, as leader Kate frequently delivers swift retribution for his misdeeds. This unpredictable, self-serving nature makes him the story's go-to source of comic relief and unexpected plot disruptions.
