As Yotsugi's words sink in, Koyomi remains unfazed. He reasons that his experiences as a vampire must have come with a price. One that he should have to pay. Yozuru commends Koyomi for his acceptance, but tells him that while there is no way to undo the progress of his transformation, there is a way he can stop it from progressing further: he must no longer use his powers as a vampire. Yotsugi informs Koyomi that he can still use his blood to feed Shinobu, but he shouldn't do it too often, and not to the point where he gains any powers. Yozuru warns him that if he were to progress further toward being a vampire, she would have to kill him, as is her duty as a specialist. This raises Shinobu's ire, and she tells Yozuru that if Koyomi were to die, the restraints on her would be released, returning her to her status as lord of the vampires. She would use that power to kill Yozuru. Yozuru accepts the challenge. Yotsugi, not wanting to see the others fight, urges Koyomi to never use his powers again, in order to keep things the way they are. Reluctantly, Koyomi promises to stop using his powers. Internally, however, he has doubts as to whether or not he can. He knows that if someone he cares about were going to die he wouldn't hesitate to use his powers to save them. Later, as Koyomi and Yozuru are discussing the reasoning behind her focus on killing immortal apparations, Yozuru receives a call from Izuko. Yozuru tells Koyomi and Yotsugi to go to Suruga's house immediately, to check on his sisters. They arrive to find not only Koyomi's sisters, but also Suruga missing. In their place is a series of paper cranes. Yotsugi explains that the bird shape indicates that the kidnapper is after Tsukihi, the phoenix. They meet back up with Yozuru, who explains that the man behind the kidnapping is Teori Tadatsuru, an apparation specialist and doll master. Like Yozuru, Teori is a specialist who focuses on killing immortal apparitions. Yozuru warns Koyomi that he can't use his power
肉体の吸血鬼化が進行していた暦。斧乃木余接からは、これ以上吸血鬼の力を使わないよう忠告を受ける。だが、そんな時、火憐と月火の身に危険が迫り―――。
육체의 흡혈귀화가 진행하고 있던 코요미. 오노노키 요츠기로부터 더 이상의 흡혈귀의 힘을 사용하지 말라는 충고를 듣는다. 하지만 때마침 카렌과 츠키히의 신변에 위험이 닥치는데……
肉体正在吸血鬼化的历，从斧乃木余接那里接受了不要再使用在此之上的吸血鬼力量的忠告。但是，就在此时，危险正在逼近火怜和月火。
Araragi pense que ses expériences passées en tant que vampire ont un prix qu'il doit payer. Yozuru lui dit qu'il n'y a pas de moyen d'annuler la progression de sa transformation, mais seulement de la freiner en n'utilisant plus ses pouvoirs de vampire. Yozuru le prévient que s'il continue de devenir un vampire, elle devra le tuer. Shinobu lui dit alors que cela la libérera de ses chaînes qui restreignent ses pouvoirs, qu'elle retournera à son statut de puissant vampire et qu'elle utilisera son pouvoir pour tuer Yozuru. Cette dernière accepte ce défi.
Cuando Yotsugi le dice a Koyomi que efectivamente se está convirtiendo en un vampiro, éste razona que el uso de sus poderes vampíricos debe tener un precio. Yozuru le dice que, aunque no hay forma de deshacer el progreso de su transformación, hay una manera de evitar que siga avanzando: debe dejar de usar sus poderes como vampiro. Sin embargo, esto resulta ser todo un reto cuando se entera de que sus hermanas y Suraga han sido secuestradas.
