Since 2021, TakaAizu has been active as a composer, arranger, and bassist in the doujin music scene, creating music that’s kawaii, energetic, and cool. His second album, 'Nonfiction Switch', released at the music and media-mix doujin event M3-2024 Spring on April 28, 2024, masterfully blends band sounds with electronic tones, perfectly realizing the album’s concept of capturing the on-and-off flow of emotions in a single work. Beyond composing, he also performs live in the virtual world on the VRSNS platform VRChat, making his presence felt even in digital spaces.
