Oreko Tachibana is coming back with a new manga this winter. The announcement sat inside the 13th and final volume of Firefly Wedding, which shipped on Monday, and confirms the creator will stay with Shogakukan’s Manga ONE app rather than move to print.
The preview gives one premise and no title. Two leaders who stand on opposite sides and must never fall in love: the prince of a country of men, and the chief of a country of women. That is the whole pitch so far. No start date, no page count, no staff credits.
A fast four years
Tachibana launched Firefly Wedding, or Hotaru no Yomeiri, on Manga ONE in January 2023 and ended it on February 2 this year. Thirteen volumes in a little over three years is a brisk pace for a romance series, and the ending arrived while the anime was still announcing new cast members rather than after the property had cooled.
The wrap-up came with extras. Tachibana drew seven spinoff chapters, one a month from February 2 to August 3. The first two were titled “Koi to Doku,” the remaining five “Hitokiri to Yōdō.” All seven were collected into a spinoff volume that released on Monday, the same day as the main series’ 13th volume.
English readers are further behind. Viz Media publishes the manga and brought out volume 8 on October 13, five volumes short of the ending. The English dub of the anime arrived on October 23 with Rowan Gilvie and Kieran Flitton in the leads.
The anime is still airing
Firefly Wedding‘s television anime debuted on October 9 and runs on Fuji TV’s Noitamina block, Fridays at 11:30 p.m. Crunchyroll streams it as it airs. A live-action television adaptation is set for 2027.
So the announcement lands in the middle of the anime’s first cour, which is not a coincidence. Publishers time creator news around adaptations because that is when the audience is largest, and a teaser tucked into a final volume is cheap to produce and easy to pass around.
What the premise suggests
The setup is a reversal of what made Firefly Wedding work. That series put a sheltered young woman and a professional killer into a marriage arrangement, and the tension came from one side being dangerous and the other being powerless. Here both leads hold power, and the obstacle is political rather than personal. A country of men and a country of women are two states with two rulers, so the romance has to survive a diplomatic problem before it can survive anything else.
Whether Tachibana plays it as comedy or as something heavier is unknown. Her last series leaned hard on violence, and a story about two leaders who cannot be seen to want each other has room for the same instinct.
What to watch for
Manga ONE reveals new series on a rolling basis, usually with a title, a start date and a color page a few weeks out. Expect those details to appear on the app’s own channels before anything else. There is no word on an English release, and Viz usually announces those separately and later.
For now the takeaway is simple: the creator of one of the year’s more popular romance manga has her next project lined up, and she is staying on the app that made her. Fans who followed Firefly Wedding to its ending do not have to wait long to see what she does next.
