Guillotinecutter is the archbishop of a new religion he created which purports that he is god. He is one of the three vampire hunters with Episode and Dramaturgie, who
stole both of Shinobu's (Kiss-Shot Acerola-Orion Heart-Under-Blade's) arms. Unlike the other two, he is completely human. Oshino comments that while Guillotinecutter stole two of Kiss-Shot's limbs instead of one each like the other two hunters, it does not mean he was the strongest among them. This is reflected in how he resorted to kidnap Hanekawa before his fight with Araragi.
After he was defeated, he attempts to slay fully-recovered Kiss-Shot but then he gets killed and consumed by Kiss-Shot herself.
