Volume 11 Is Already Set for February

The next book was confirmed before Volume 10 had even officially reached Japanese stores. With Volume 10 due October 20, the October 19 announcement immediately established February 2027 as the next release window.

For now, it remains an early schedule announcement. The official post does not specify the exact February date, ISBN, price, page count, store bonuses, or synopsis.

“Futari no Himitsu wa Hitotsu Yane no Shita” Continues

Volume 11 retains the subtitle Futari no Himitsu wa Hitotsu Yane no Shita, continuing the current phase of Miyagi and Sendai's story after the earlier Futari no Jikan, Iiwake no Go Sen-en volumes.

Volume 10 uses the same subtitle and arrives October 20 with 374 pages and an official Japanese price of 1,012 yen including tax.

February Also Teases an Art Book and New Usa Haneda Work

The official account did not stop at Volume 11. Its announcement also tells readers to look forward to February releases including an art book and a new work by Usa Haneda.

No titles, formats, exact dates, or pricing were provided for either project, so those details remain pending.

Why This Matters

1) The next volume is confirmed before Volume 10 launches

Readers already have a February window for Volume 11 while Volume 10 is still one day away from release.

2) February carries more than one tease

An art book and a separate new Usa Haneda work were also mentioned alongside the new volume.

3) The series now has an official global title

Yen Press publishes the English edition as Buying a Classmate Once a Week, giving the series an official English-language identity.
