Kaguya-sama: Love is War: The First Kiss Never Ends will debut in theaters in Japan on December 17, 2022. Its tagline can loosely translate to “Romance is a little lonely.” There is also a new key visual featuring the main characters. Since the movie will come out around Christmas, the design of the poster has a lot of holiday influences.

Since the third season of Kaguya-sama: Love is War covered Chapter 95 to Chapter 137, the movie will likely pick the story up from there. This means that the film will show events from Chapters 142 to 151, which are in Volume 15 of the tankobon. The First Kiss Never Ends arc from the manga advances Kaguya and Miyuki’s relationship after what happened in the Dual Confessions Culture Festival Arc.
Kaguya-sama: Love is War is a romantic comedy manga in Weekly Young Jump. It focuses on Miyuki Shirogane and Kaguya Shinomiya’s attempts to make the other confess their love first. While they both reciprocate their romantic feelings, their pride prevents them from simply showing affection. The manga will end on November 2, 2022 after running for seven years.
Kaguya-sama: Love is War: The First Kiss Never Ends will air in Japan on December 17, 2022. It is unknown at this point when or if it will appear in the west.
