Zim

Zim is an Atrihea City High combatant whose brutal attack on Angy makes him the target of Gustav's disguised retaliation during the interschool exchange.

Biography

Brutality against Angy

Zim overpowers Angy, hardens his body into stone, and raises a diamond-like fist to stab through her stomach even after she nears unconsciousness. Falco appears to stop the blow, but the rescuer is actually Gustav Oslov in disguise. Zim's refusal to show restraint gives Gustav both a personal motive and public cover for a severe counterattack. (Chapters 113–118)

Punishment and bloodline loss

Gustav methodically shatters Zim's rocky protection, embeds the opponent's own stone spikes into his body, and continues until acquiring Flesh Hardening. The final strike throws Zim outside the ring with shattered bones and life-threatening wounds, allowing medical staff to intervene. He survives the immediate event, but loses the bloodline and becomes the example used to teach Angy how fear can shape later reactions. (Chapters 119–121 and 144–145)

Appearance and personality

Zim is a male student whose body takes on a rocky, increasingly spiked form when his bloodline activates. He is cruel, dismisses Angy's pleas as weakness, and assumes durability permits unrestricted violence. That confidence collapses once Gustav proves able to break the hardened surface and inflict greater pain. (Chapters 113–120)

Bloodlines and abilities

Flesh Hardening converts Zim's skin and body into durable rock capable of resisting bullets and vehicle-scale collisions. He can form diamond-like striking points and grow spikes for offense. Repeated concentrated force can crack and destroy the armor, and Gustav's acquisition removes Zim's access after the match. (Chapters 113–120)
