Koyomi and Yotsugi land at the base of the mountain, where they are surprisingly met by Ougi Oshino. She talks with Koyomi for a while about his current situation and his upcoming confrontation with Teori. Koyomi and Yotsugi begin their journey up the mountain. The two discuss how they will be able to rescue Koyomi's sisters and Suruga. Koyomi hopes that they'll be able to sneak past Teori and get them without him noticing, but Yotsugi is doubtful of that plan. She expects that Koyomi will have to convince Teori to let them go, as this is how Koyomi normally deals with his opponents. Yotsugi then briefly explains how she was created. Back during their college days, Yozuru, Teori, Meme, and Deishu Kaiki did a project to create and artificial shikigami from the corpse of a human, under the direction of Izuko. Yozuru and Teori both fought for 'ownership' of Yotsugi, but in the end, Yotsugi chose to stay with Yozuru. This led to a falling out between Yozuru and Teori. Yotsugi discloses that the reason she is telling Koyomi this is because, if things were dire, he could choose to hand over Yotsugi to Teori in order to resolve the situation. Koyomi refuses to consider the option. He instead instructs Yotsugi to find the hostages, and use her power to immediately get away, while he distracts Teori. Yotsugi points out that if she were to leave, Koyomi and Shinobu would be left helpless before Teori. Yotsugi halfheartedly suggests offering Shinobu to Teori, which Koyomi refuses. Yotsugi points out that Koyomi's desire to have the hostages rescued while not being willing to give up either Yotsugi, Shinobu, or himself shows a lack of maturity. She then suggests that if she were to get close enough to Teori, she could use her powers to kill him before he has a chance to react. Koyomi is shocked at the suggestion. He wants to preserve what humanity is left in Yotsugi, and if she were to kill Teori, she would lose it. The two reach the shrine, and observe Teori. He is sitting on
