In the aftermath of the previous day, Araragi is about to enter his classroom when Hanekawa informs him that a student absent all year is finally attending. The story pushes further into the past, as more of “what” makes Koyomi Araragi is revealed.

Araragi and Hanekawa visit Oikura and learn the painful story of her family's past.

The group relocates to the North Shirahebi Shrine where Izuko Gaen tells them the story behind the location and the effect Shinobu's first minion had on it.

Gaen assembles Koyomi, Shinobu, Mayoi and Yozuru and reveals that Ougi is the responsible for some of the previous ordeals they faced.

Koyomi reexamines his options and is drawn to the bath in the Kanbaru household, but is suddenly attacked by the Rainy Devil. Koyomi narrowly escapes the danger, only to meet more people from this world he supposedly "knows".

While taking a bath in the Kanbaru household, Koyomi has an encounter with an unknown yet familiar face who starts up a conversation about knowledge.
