Manga centering on high school koto club launched in 2012

Shueisha opened a website on Thursday to announce that Amyū's Kono Oto Tomare! (Stop This Sound!) manga is getting a television anime adaptation.

Jump SQ. had launched a countdown website last week for a "big announcement" that now links to the anime announcement. The anime announcement site is streaming a video.

The August issue of Shueisha's Jump SQ. magazine had teased earlier this month that the magazine's September issue on August 4 would have an important announcement for the manga. The manga will feature on the September issue's cover, and the newest chapter will have an opening color page. The issue will also feature a clear file for the manga.

Ryōma Mizuno is serving as the series director at Platinum Vision (Saiyuki Reload Blast, Servamp, Devils' Line). Ayumu Hisao (Devils' Line, Sword Oratoria: Is It Wrong to Try to Pick Up Girls in a Dungeon? On the Side) is both writing and overseeing the scripts, Junko Yamanaka (ReLIFE, Servamp) is the character designer, and Toshimitsu Kobayashi (Spice and Wolf II, Aoharu x Machinegun) is the sub-character designer. Yamanaka and Kobayashi are also both serving as chief animation directors, and Hideaki Oba is the adviser.

In the story, Takezō is the last remaining member of the koto club, a club dedicated to the traditional Japanese string instrument. If he doesn't find new members, the koto club will be terminated. One day, Takezō is alone in the club room when a student barges in and demands to join. The student is delinquent Chika Kudō, a boy who even scares delinquent upperclassmen at other schools.

Amyū launched the manga in Jump SQ. in August 2012, and the 18th compiled volume will ship on August 3. The manga has more than 2.5 million copes in print.

Update: Added announcement video.
