Monaca's Producer name (10-dayP) originated from the number of days he took to learn the basics of Vocaloid/music-making, composing the song, setting the lyrics and uploading his work. He's the final member of s10rw, which is a group of Vocaloid producers centered on electronic music.

Like with the rest of the group, Monaca is not a chronic uploader in Nico Nico Douga, having only produced a handful of songs even though he started his Vocaloid career in 2008. However, he has participated in more than 10 CDs/compilations including EXIT TUNES Presents GUMIism.

Monaca's style is very different from his co-members. His music is described as technopop, electronic pop and shoegaze, although his music incorporates post-rock, chiptune, and ambient. He also does wonderful piano and guitar ballads. Distinct characteristics of his upbeat music include simple but repetitive electronic beats reminiscent of early Vocaloid works (kz, azuma, etc.). His ballads almost always have piano music laced with subtle electronic beats which gives off an ambient/trance-like appeal. Aside from that, he also uses orchestral effects.

Monaca uses Hatsune Miku (append and not) in almost all of his works, although recently, he has started using GUMI, too. In this part, he's also unique from his co-members because instead of giving Miku a breathy, gentle voices, he tunes her sharp and ringing. His GUMI is also crisp and edgy. Read more on Last.fm.
