“Floor Killer” Ignites the Gnosia Narrative
“Floor Killer” brings a new auditory dimension to the Gnosia anime, which premiered in October 2025.

Prior to this, the anime’s ending theme was “Loo% Who%” performed by Ling Tosite Sigure, which was announced earlier in September 2025 and debuted with the series. Anime series occasionally feature multiple opening and ending themes across different cours or significant narrative arcs, offering diverse musical interpretations of their stories.
Ling Tosite Sigure’s “Loo% Who%”
Ling Tosite Sigure’s “Loo% Who%” served as the initial ending theme for Gnosia, setting an atmospheric tone for the series from its premiere on October 12, 2025. The band is renowned for its distinctive rock sound, and their contribution helped establish the anime’s enigmatic ambiance. The anime itself is produced by Domerica and directed by Kazuya Ichikawa.

Their distinctive blend of hip-hop elements offers a unique flavor to the shows they contribute to.
