Shikao Suga is taking on double duty for the Horror Collector anime—the singer-songwriter will perform both the opening and ending theme songs for the series, which he also wrote.

NHK announced the news on Saturday ahead of the anime's October premiere on NHK General. The announcement marks another step forward for the adaptation of Midori Satō's Horror Collector novel series, which has been running since 2015 and recently reached its 28th volume.

Horror Collector follows a mysterious boy in a red hood who travels from town to town investigating internet legends and paranormal phenomena. While most creepypastas and cryptid sightings are just urban legends and pranks, the series explores what happens when people encounter the genuine article—and whether the hooded figure is a savior or proof that real monsters exist.

The anime marks the first major screen adaptation of the property. Niko Yuki created a manga version that ran in Kadokawa's Monthly Comic Gene magazine during 2021-2022, published as a single volume in March 2022. Yen Press is bringing both the original novels and Yuki's manga adaptation to English-speaking audiences through its "JY for Kids" middle-grade imprint, with the sixth novel volume and manga collection having released in May 2025.

Suga's involvement adds a noteworthy creative layer to the project. Beyond writing both themes, his performance style should complement the show's blend of internet horror and coming-of-age storytelling. The themes will bookend each episode when the anime airs this fall on NHK General.

With an established fanbase built over more than a decade through the novels and manga, Horror Collector arrives at a time when anime adaptations of Japanese horror and supernatural properties continue to draw international attention. The NHK platform also signals the broadcaster's confidence in bringing the series to a broad domestic audience.
