Cult

Cult (カルト) is a young necromancer tasked with defeating the living dead that swarmed towns and wreck havoc. He is often seen with Lily, another young necromancer whose seal was fading.

Appearance
Cult is a young boy with tall and lean stature. He had light, short hair and blue eyes, and often wore his casual outfit of a striped shirt with short cuffs that had black hems, and a white long-sleeved shirt underneath. He also wore long, black baggy pants, ankle-high socks, and black shoes. He carries a revolver used to kill the living dead on a utility waistbelt.

Personality
He is seen to be very protective of Lily, even going far as to mercilessly killing any living dead that comes near her and ultimately warping her original form in the end. He holds a nonchalant and dismissive demeanor when it comes to other matters, especially when watching the church punish those who don't follow its rules.

Although he claims he doesn't necessarily hate the living dead, he takes great responsibility in protecting the civilians and killing the living dead upon sight.

Amplification
The seal on his hand allows him to utilize some of his power to shoot the living dead using a revolver.

Contract
By forming a circle and inscribing his name around a potential familiar, Cult decided to use it on Lily after he killed her, whose corpse eventually turned into one of the living dead and cause her to lose her memories.
