The official Twitter account for the NisiOisin Anime Project announced on Sunday that the Kodansha Box imprint will publish Owarimonogatari , NisiOisin's latest Monogatari book, this fall. In addition, the October issue of Kodansha's Bessatsu Shonen Magazine will publish the first story from the book, "Ōgi Formula," on September 9. The story will follow what happens after the protagonist Koyomi Araragi meets a mysterious girl named Ōgi Oshino.

VOFAN is not only illustrating "Ōgi Formula," but also a poster bundled with the Bessatsu Shonen Magazine issue.

Owarimonogatari was previously planned for this past April and then this summer. A Zokuowarimonogatari book was previously slated for next year, although NisiOisin has not said if this is still the case.
