Kaguya-sama: Love Is War is officially getting a “Final Chapter”—and it’s now confirmed to be in production. The announcement was posted through the series’ official channels, stating that the project will be created from a completely new story draft written by original creator Aka Akasaka, with a teaser video released alongside the news. https://kaguya.love/news/?id=69489

What you won’t find in the official post (yet): a release date, exact format details, or where fans outside Japan will be able to watch it. Multiple reputable outlets are calling it a brand-new theatrical feature film, but for now the safest wording is that a “Final Chapter” production has been greenlit and is underway. https://kaguya.love/news/?id=69489

If you’re new to the franchise: Kaguya-sama: Love Is War is a wildly popular rom-com set at an elite academy, where two top students are secretly in love—but far too proud to confess first. The result is an escalating “battle of wits” that mixes rapid-fire comedy with surprisingly heartfelt character moments.

What We Know So Far

Here’s what the official announcement clearly confirms:

A “Final Chapter” is officially in production

Both the official site and Aniplex’s project news page state that Kaguya-sama: Love Is War “Final Chapter” production has been decided and is actively being worked on.

Aka Akasaka is providing a brand-new original story draft

The official wording emphasizes that this is being produced from a completely new original draft/outline by Aka Akasaka (not simply a routine continuation announcement).

A teaser video has been released

The announcement includes a “teaser video” (特報映像). If you want the safest, most accurate link, use the official announcement page(s), where the teaser is referenced/embedded.

Is it a theatrical movie?

The short official post focuses on “Final Chapter production decided,” while multiple reputable outlets explicitly describe it as a completely new theatrical feature film. Until the production committee publishes a full-format press release in the official post itself (or a dedicated film page with clear wording), treat “theatrical film” as widely reported rather than the single-line official phrasing.

About the Source Material

Kaguya-sama: Love Is War began as a manga written by Aka Akasaka and published by Shueisha (Young Jump Comics imprint).
At its core, it’s a romantic comedy about two brilliant student council members who refuse to admit their feelings first—turning everyday school life into a dramatic (and hilarious) mind game.
