Tsubasa Hanekawa is the target of a vicious tiger apparition, and Koyomi Araragi is nowhere to be found. With strange events unfolding in his absence, the usually modest genius must fend for herself against the threat.
The new semester also brings decisions for Koyomi, whose approaching graduation leaves him weighing his future, the relationships he will form, and the friends he will save. Meanwhile, apparitions, oddities, and gods remain a presence around his close-knit circle. Alongside Hanekawa are the vampire Shinobu Oshino, the athletic Suruga Kanbaru, the spirit Mayoi Hachikuji, Koyomi's admirer Nadeko Sengoku, and his girlfriend Hitagi Senjougahara. These continuing supernatural disturbances form the backdrop to a time when Koyomi must choose which paths to take.
