Takayama appears as a main character in "The Asylum Session," credited under "Characters & Voice Actors" with Masami Iwasaki as the voice actor. While synopses, plot summaries, reviews, and discussions emphasize other characters—such as Hiyoko, Akira, and the stadium slum residents—alongside the central conflict of the street-art event and police demolition, these sources do not elaborate on Takayama's background, story role, relationships, character development, or involvement in media beyond the original film.
