Story

◎Urban Fantasy × Suspense × Girl Meets Girl

The setting is Kasumigi, an ordinary rural town.

One day, the peace is shattered by a gruesome murder. Hina, a rumor-loving high school girl on a hunt for a scoop, accidentally stumbles upon the scene of the crime. Standing there is a mysterious girl named Chitose.

Convinced she has found a "headline" story, Hina labels her the killer.

In exchange for keeping her secret, Hina makes a daring proposal: she wants an exclusive "interview."

Characters

Hina Higano

The protagonist. Her hobbies include surreptitious photography, wiretapping, and tailing subjects—she lives for juicy rumors. She has a relentless drive to see anything "interesting" with her own eyes. After a run-in with the school's disciplinary committee, she has (mostly) retired, though she still can’t resist bugging the staff room.

Chitose Tsukishima

A girl found at the murder scene. Claiming to be an "Angel," she is deeply involved in the incident. She is notoriously bad with electronic devices.

Ruri Kuchinami

Hina’s classmate at Kasumigi High. Always listless, she spends most of her classes sleeping. Despite her appearance, she comes from an incredibly wealthy family—a true "Ojou-sama."

Yoshihito Hayama

A detective dispatched to investigate the murder. His overbearing attitude and tendency to take credit for others' work make him unpopular among his colleagues and subordinates.
