A booklet included in the Blu-ray volume of Ougi Dark arc from the second installment of Owarimonogatari anime series, which ships on Wednesday, has revealed that Zoku Owarimonogatari, the sixth and last volume of NisiOisiN's Monogatari Series: Final Season novel series, will receive an anime adaptation in 2018. The official website has revealed a preview and a key visual (pictured).
Zoku Owarimonogatari contains the Koyomi Reverse arc, and was published by Kodansha in September 2014. The arc takes place after the college entrance exams but before the events in Hanamonogatari.
The first anime adaptation of the Monogatari Series: Final Season novel series aired in Fall 2014 with Tsukimonogatari. The second anime adaptation covering the third and fourth volume, Owarimonogatari, followed in Fall 2015. Koyomimonogatari, the second volume of the series, was adapted as a 12-episode net anime and streamed through its titular smartphone application earlier last year.
The sequel to Owarimonogatari, which is the series' recent anime adaptation, aired as a two-day special on August 12 and August 13, adapting the Mayoi Hell, Hitagi Rendezvous, and Ougi Dark arcs from the fifth volume.
