Personal preferences and community notes
- A long collaboration with an illustrator: early song art was mostly drawn from public works by various artists on Piapro, while later art has mostly been handled by Honda Souichi; the two are close and call each other by nicknames.
- Contact with producers of his generation: he is close to the producer Kakashi, the two have remixed each other’s songs and interact often on Twitter.
- A personal alt account: he runs a Twitter alt named Numamitaina (meaning “like a swamp”) for everyday trivia, and has uploaded two covers on YouTube under that name.
- In-house writing at KAMITSUBAKI: within the studio he frequently writes for KOKO.
- Stated preferences: he has tweeted that he likes BL (self-described as a fudanshi); his favourite utaite are WaMi, Rei and Miyashita Yuu.
- Musical background: he loved singing from childhood and went to karaoke often; he began learning an instrument properly in the second year of middle school, played in a band in high school, and performed the band’s originals at a live house.
Style summary: Onuma Parsley’s trajectory is unusual even among KAMITSUBAKI creators — from an early phase of “Piapro artwork plus gentle songwriting”, through large-scale deletions and a stylistic rebuild, to a settled identity of “electronically charged poison pop”, and then a turn to self-performed singer-songwriter work after pausing his producer activity. That curve is itself a sample of KAMITSUBAKI’s model in which creators are free to keep transforming.
Upload Statistics and Scale of Output
| Metric | Figure |
|---|---|
| Vocaloid originals uploaded | 26 tracks posted to niconico at the time of record |
| Hall of Fame entries | 6 tracks reached the Hall of Fame (100,000 plays) |
| Legend entries | 1 track reached Legend status (1,000,000 plays) |
| Voice libraries used | Hatsune Miku, v flower, KAFU, COKO |
| Platform character | YouTube play counts are often far higher than niconico’s; the best-known track, “Egoist”, has reached tens of millions of views on YouTube |
Why the scale matters: achieving six Hall of Fame entries and one Legend entry from a modest total number of uploads shows an unusually high hit rate — a major reason Onuma Parsley was counted among the founding members when KAMITSUBAKI STUDIO was established.
