Houshou Marine (宝鐘マリン) is marking her 7th anniversary the way she usually does — with an original anime MV that goes well beyond what most VTuber music releases attempt. きゃぴ (Kyapi) comes with a full production credits list running dozens of names deep, animated by SANZIGEN, the professional studio behind titles like Land of the Lustrous and the Fate/kaleid liner Prisma Illya films.
Written by teniwoha
Lyrics, composition, and arrangement all come from teniwoha, a Vocaloid producer and novelist who’s been active since 2010 and built a reputation on rhyme-heavy, wordplay-driven lyrics wrapped around mystery and yokai storytelling — best known outside the Vocaloid scene for writing Ado’s “Eien no Akuru Hi” and “Giragira.” Recording and mix work comes from Maruoka Shiori (丸岡詩織), a name that shows up regularly across hololive’s higher-production original releases.
Marine’s Own Hand in the Story
Director, storyboard, and editing lead Tomomi Umezu (梅津朋美) shares the storyboard credit directly with Marine herself — a detail that fits her long-standing reputation as an artist who stays hands-on with the visual side of her own music releases rather than handing the concept off entirely. Choreography comes from Wata (わた), with art direction and color script work from Shin Joseph.
A Full Studio Production
Beyond the core creative leads, the credits stretch across animation direction, CG direction, modeling, rigging, compositing, and motion capture teams — the kind of full-scale anime production pipeline that’s rare even among hololive’s more ambitious music releases. It’s a clear sign of how much weight is put behind Marine’s anniversary MVs specifically, year over year.
Seven Years of Going All Out
Marine has built a track record of treating her anniversary songs as genuine creative statements rather than simple celebratory covers, and Kyapi continues that pattern with one of the more heavily produced entries in her catalog yet. Seven years in, the scale of these releases hasn’t shrunk — if anything, it keeps growing.
