Tsubasa Cat, Part Four. After suppressing the cat, Oshino explains Tsubasa's situation to Koyomi. Koyomi realizes that he may need Shinobu's powers to help him bottle up the oddity. The problem escalates when Koyomi learns that Shinobu has gone missing. Enlisting the help of his friends, he looks for Shinobu to no avail. The cat soon escapes from Oshino, then goes after Koyomi; this time, however, she sides with him and aids in searching for Shinobu. The two have conversations regarding Koyomi's interactions with oddities while they scour the city. The search proves to be difficult even with the cat's keen sense of smell and hearing. The conversation gradually switches over to Tsubasa's situation. The cat explains that there is a way to confine her without relying on a vampire, that she is the personification of Tsubasa's stress, and that she knows exactly what is causing it. She remarks that Koyomi can deal with it easily. The oddity then reveals that Tsubasa being possessed by the cat was because of the stress that she felt from her unrequited love for Koyomi, and that the oddity itself may be sealed away for good if Koyomi falls in love with Tsubasa.
