Koyomi, Suruga and Shinobu fight with the mysterious apparition, which seems like a hybrid of all the oddities Koyomi had dealt with in the past. Upon defeating the apparition, the gang meet up at the shrine with Izuko Gaen, who introduces herself as the sister of Meme Oshino, Izuko Oshino. She tells them that the task she asked Koyomi to do was, in fact, related to the enemies they had encountered so far and the main objective was the samurai armor, who she tells them is actually the first minion of Shinobu mentioned in Onimonogatari. She tells them of the tale of the first minion, the original apparition killer, what became of him, and how he came to this town... 15 years ago.
