SHAFT — the studio behind Puella Magi Madoka Magica and the Monogatari series — has been revealed as the animation production house for the upcoming TV anime of Ito Ikkado’s hit manga The Long Summer of August 31, with a live-action drama adaptation also confirmed. Both announcements dropped simultaneously on August 31, 2026 via Kodansha’s official channels (Japanese).
What Is The Long Summer of August 31?
If you have not yet picked up the manga, here is the setup: high school students Takaya Suzuki and Kana Takagi are the only two people who know they are trapped in an endlessly repeating August 31st — the final, dread-inducing last day of summer break. Every morning they wake to the same day. Only they retain memories across each loop. And the reason the loop persists has something to do with a very specific goal Suzuki has yet to accomplish over summer — which the manga describes, with cheerful frankness, as a romance-adjacent bucket-list item.
Creator Ito Ikkado — whose earlier work Boku wa Oniku Janai built a loyal seinen readership — launched the series in Kodansha’s Morning magazine in March 2023. Three years and 13 volumes later, the manga has earned itself an anime-and-drama double billing. Kodansha’s own genre label? “Youth time-loop comedy that confronts romance head-on” — which is exactly the kind of premise SHAFT was built to visualise.
SHAFT at the Helm — Why It Matters for Anime Fans
SHAFT is not a neutral casting choice. The studio has built its reputation on anime that treat visual language as a storytelling instrument: the stark shadow-play of the Monogatari series, the stained-glass surrealism of Madoka Magica, the breakneck rhythm of Nisekoi. A time-loop romance anchored to a single repeating date — the same morning, the same faces, a thousand subtle variations playing out across 13 volumes — is a concept that maps naturally onto SHAFT’s skill set.
At this stage there is no release window, no director, no announced cast. The official series X account (@831longsummmmer) promises further details in due course. But for Singapore anime fans who have been tracking SHAFT’s output, the studio name alone is enough to put this firmly on the watchlist. As for Ito Ikkado’s own reaction to the announcement: the author’s comment, as carried in the Kodansha press release (Japanese), was refreshingly succinct — “That’s quite the summer announcement.”
A Live-Action Drama Is Also Coming
Confirmed alongside the TV anime is a separate live-action TV drama adaptation. Network, cast, and air date have not been disclosed — both the anime and drama appear to be in parallel early development. The dual adaptation approach (TV anime plus concurrent live-action drama) has become a notable Kodansha playbook for its bigger titles, and the simultaneous announcement here suggests the publisher sees strong crossover potential for The Long Summer of August 31 beyond a strictly anime-watching audience.
Where to Read the Manga Now
Singapore readers can get into the story well ahead of the anime. Seven Seas Entertainment has been releasing the English edition since April 2025, and Volume 6 landed in August 2026 — six volumes of Suzuki and Takagi’s endless summer are available in English right now, with more to follow as the remaining volumes roll out. The series is also available in digital English on Kodansha’s K Manga platform, accessible from Singapore. As a launch promotion, Kodansha also made four volumes free on Comic Days for the week following today’s announcement.
