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.
