Guillotine Cutter, a priest and archbishop of an unnamed religious order devoted to purging supernatural forces, commands covert operations against anomalies with calculated precision. His hedgehog-spiked hair, crimson scarf, and flowing priestly garb frame pointed ears that evoke vampiric traits, though he remains entirely human. A shadowy strategist within an elite anti-oddity unit, he enacts his divine mandate through merciless pragmatism, dismissing the existence of the very beings he systematically destroys.

In confronting Koyomi Araragi, he abducts Tsubasa Hanekawa, leveraging her life to compel surrender—a tactic highlighting his moral ambivalence in service to higher doctrine. Preferring psychological warfare over brute force, he exploits emotional vulnerabilities to dominate foes. Araragi thwarts him by harnessing vampiric metamorphosis, ensnaring him with root-like limbs. True to his word, Guillotine Cutter restores Kiss-Shot’s severed arms post-defeat, only to meet his end as her resurrected power consumes him. His demise concludes his singular narrative arc, leaving no legacy beyond this confrontation.
