Sara Hoshikawa (星川サラ) has a new original song, and the title alone tells you exactly what you’re getting: Chuinkle Princess (ちゅいんくる・ぷりんせす), a made-up, sugar-rush of a word that captures her whole persona before the song even starts. Hoshikawa’s video description sums up her whole philosophy in one line: she can’t function unless she’s constantly, dramatically smitten with something. This track is basically that idea set to music.
Co-Written by Hoshikawa Herself
What stands out here is the writing credit. Chuinkle Princess was written by Medansy of TRIFRONTIER alongside Hoshikawa herself — she’s not just performing this one, she had a direct hand in shaping it. Medansy has built a reputation as one of the go-to names for high-energy idol and VTuber tracks, having worked across hololive, Nijisanji, and Dennou Shoujo Shiro projects, with a knack specifically for songs built to make a crowd lose it. Pairing that pedigree with Hoshikawa’s own input on the lyrics gives the song a much more personal fingerprint than a typical outside commission.
What the Song Is Going For
Everything about Chuinkle Princess leans into maximalist, can’t-sit-still cuteness — the kind of track built for someone whose whole brand is self-declared main character energy. Hoshikawa has always leaned hard into her “influencer princess” persona, and this song reads like the theme music for that character: a little chaotic, a little self-aware, entirely unbothered by anyone who isn’t fully on board.
The Visual Side
The MV comes from studio Lit., with Ririppi handling story and supervision, character illustration from Tenneko (貂猫), comic-style art from Yukinko (ゆきんこ), and movie work from naco. That’s a full production team dedicated to giving the song its own visual identity rather than a simple lyric video, which tracks with how much studio Lit. tends to lean into narrative-driven MVs for original VTuber songs.
Why It Fits Her
Hoshikawa has built her run in Nijisanji around leaning fully into a bright, unapologetically girly persona, and an original song is a real statement of intent — it’s not a cover borrowing someone else’s voice, it’s a piece of music built specifically around who she is as a performer. Having her name on the lyric sheet only reinforces that this is meant to be read as Hoshikawa’s own song, not just a song she happens to sing.
