Kenmochi is mainly in charge of music production, composing, arranging, and song writing. The concept of the group that Kenmochi and Dir.F had in the early years was a Japanese folklore-style like Perfume. The names of songs are one of famous people such as Napoleon, Ryoma Sakamoto and Wright Brothers. 2017's SUPERMAN expounded on this concept with the idea of larger-than-life people such as Genghis Khan, Aladdin, Kamehameha, and more. In addition, each song refers to historical events, great people, or moments in popular culture. Furthermore, Kenmochi's lyrics seem to sound meaningless, but the soundtrack maker intentionally writes the lyrics in that way. Many songs feature puns or play on words confusing to non-Japanese speakers. KOM_I said that she wants her listeners to enjoy her comical lyrics without thinking of "meaning" of the lyrics.
Previously KOM_I only acted as the group's vocalist, but she began to participate in the production process with Rashomon. KOM_I began to write lyrics for the 2016 release, UMA. However, Kenmochi returned to writing all lyrics and arrangements for 2017's SUPERMAN.
