Natsume Ono is heading back to the Dowa Kingdom. KORORE, a new manga connected to both ACCA: 13-Territory Inspection Department and BADON, will begin in Square Enix’s Monthly Big Gangan on February 25, 2027.
The magazine announced the series through its official X/Twitter account. Its debut is scheduled for the publication’s third issue of 2027, giving readers a firm date for the next addition to Ono’s shared setting.
Another territory gets its name on the cover
KORORE takes its title from one of the Dowa Kingdom’s 13 territories. That follows the naming approach used for BADON, which also shares its name with a territory in the world introduced by ACCA.
That connection is the central detail here: this is not an unrelated Ono series, but another manga within an established setting.
However, the supplied announcement does not outline KORORE’s story, identify its lead characters or explain how directly its events connect with the earlier manga. Whether familiar faces will return is therefore still an open question. A shared world is confirmed; a particular crossover storyline is not.
The route from ACCA to BADON
The original ACCA: 13-Territory Inspection Department ran in Monthly Big Gangan from June 2013 until October 2016. Square Enix collected it into six volumes, and Yen Press published the manga in English.
Its television anime followed in 2017, with Crunchyroll streaming the adaptation. An OVA sequel, ACCA: 13-Territory Inspection Dept. Regards, arrived in February 2020 and was also streamed by Crunchyroll.
Ono subsequently launched BADON in the same magazine in January 2019. That manga finished in March 2024, with its ninth collected volume released by Square Enix the following month.
KORORE now adds another title to that publishing history. Importantly, this announcement concerns a manga launch, not a new ACCA anime season or an animated adaptation of the upcoming series.
Why it is worth watching from Malaysia and SEA
Analysis: For readers in Malaysia and Southeast Asia deciding whether to follow this announcement, the useful distinction is between the creative news and access details. Ono is expanding an existing fictional world, but the February 25 date refers specifically to the Japanese magazine debut.
The source does not announce an English edition of KORORE, a Malaysian release or regional distribution arrangements. Earlier English publication of ACCA should not be treated as confirmation that the new series will receive the same treatment.
For anyone whose entry point was the ACCA anime, though, this is a reason to keep an eye on the manga side of the franchise. The announcement points towards another part of its setting without yet giving enough information to judge the new story—or declare earlier reading essential.
An established creator, another new chapter
Ono made her manga debut in 2003 with La Quinta Camera. Her bibliography also includes House of Five Leaves, Ristorante Paradiso, Not Simple, Lady and Oldman and Have a Great Sunday.
For now, the takeaway is straightforward: KORORE begins on February 25, 2027, and returns Ono to the world shared by ACCA and BADON. Plot details and any English-release news remain things to watch for, rather than promises attached to this reveal.
