Volume 10 Cover and Announcement

The School Trip Moves the Story to Okinawa

Volume 10 takes Saku and the group away from their usual environment for a school trip to Okinawa. The official synopsis presents the group enjoying the unfamiliar atmosphere and spending time together.

The trip, however, is clearly not being treated as a simple vacation. Beneath the bright setting, the novel is preparing another shift in the characters' relationships.

Haru Faces New Distance From Her “Partner”

Haru is one of the central names in the new synopsis. As the person described as her “partner” begins pulling ahead, she is left with increasingly complicated feelings.

Gagaga Bunko has not revealed exactly where that tension will lead, leaving the actual development for the full novel.

The New Cover Is Now Official

Volume 10's new cover features artwork by raemz, giving the November release its final visual identity.

Gagaga Bunko has also confirmed a Japanese retail price of 946 yen including tax and the ISBN 978-4-09-453317-0.

Why This Matters

1) The story moves to Okinawa

The school trip gives the cast a setting outside their usual everyday environment.

2) Haru receives a new emotional conflict

The synopsis signals that the trip will involve more than sightseeing, particularly through Haru's changing relationship with her “partner.”

3) Volume 10 is a major series milestone

Reaching a double-digit main volume gives the story room to push long-running character relationships into another phase.
