Kaburagi

Initially presenting himself as a gloomy and apathetic armor repairer, Kaburagi conceals his true nature as a highly capable cyborg. Following a tragic past incident where his comrade was ruthlessly scrapped for breaking the rules, he lost all hope in the rigid corporate System and resigned himself to a mundane, emotionless life of eliminating "bugs" to survive. However, his dull existence is turned upside down when he crosses paths with the relentlessly optimistic Natsume. Her unwavering determination to fight and dream profoundly impacts him, slowly melting his cold exterior and reigniting his dormant courage. Driven by a deep moral compass and a newfound desire to protect her and the other Tankers, Kaburagi ultimately transforms from a compliant cog in the machine into a fierce, selfless revolutionary willing to dismantle the entire world order to forge a freer future.
