wotaku is a Japanese music producer and composer, primarily known for creating vocaloid songs that have served as the source material for manga adaptations. He is credited as the original creator behind the manga Shanti, which is based on his vocaloid song of the same name. As a vocaloid producer, also known as a Vocaloid P, wotaku handles the composition, lyrics, and arrangement for his musical works. He has been active since around 2017, often collaborating with other artists for illustrations and mastering on his music projects.

The manga Shanti serves as a key example of wotaku's work being adapted into another medium. Published in 2024, the manga is set in a 1920s city and follows a boy named Sangha whose life is disrupted by the mafia. While the story and art for the manga adaptation are credited to Shinano Sano and Ammon Nigata respectively, the work is explicitly based on the vocaloid song of the same title created by wotaku. The original song, released in September 2021, features the vocaloid KAITO and incorporates musical elements described as a fusion of electronic swing with Chinese-inspired motifs, set against a story backdrop involving the underworld of Chinatown.

Regarding his artistic identity, wotaku's work is noted for certain recurring thematic elements. His lyrics and the narratives of his songs often explore darker or more cynical subjects, which has been described as a characteristic of his musical style. In contrast to the sometimes heavy themes of his music, he has publicly commented on the enjoyment of listening to pop music in everyday settings. His interests outside of music, which include playing various video games, occasionally surface in his online presence and provide insight into his creative influences.
