Sara Hoshikawa (星川サラ) is releasing a cover of ReoNa‘s Seimeisen (生命線) — the theme song of Tsukihime -A piece of blue glass moon- — and this one isn’t a casual pick. The video premieres on October 28, 2026 at 8:00 PM JST on her YouTube channel, and if her own words about the song are anything to go by, it’s been a long time coming.
Why Sara Hoshikawa Chose ‘Seimeisen’
In the video description, Hoshikawa writes that this is a song from a game she loves, from a work that has stayed with her so deeply that every time she looks at the moon since the day she cleared it, her chest tightens. That’s not cover-selection-by-committee — that’s someone paying off a personal debt to a piece of fiction that genuinely moved her. She says she sang it because she wanted to leave a permanent record of how much it stirred her. It also tracks with her channel history: she’s posted a full Tsukihime -A piece of blue glass moon- let’s play playlist, so the connection to the source material is real, not cosmetic.
The Original: ReoNa’s Tsukihime Theme Song
Seimeisen (生命線) comes from ReoNa’s Tsukihime -A piece of blue glass moon- THEME SONG E.P., tying her directly to TYPE-MOON’s remake of one of its most storied visual novels. ReoNa’s originals carry a fragile, aching quality, and putting your own voice on a song that fans hold that close is a bold move. Hoshikawa, whose soft, clear singing style has become one of her signatures, is taking on exactly the kind of track where emotional sincerity matters more than technical flexing.
The Team Behind the Cover
Hoshikawa has assembled a dedicated crew for the release: Natono (ナトノ) handles the illustration, the instrumental is by KaiseiP (快晴P), mixing comes from D_MIX, and the video work is by Beesuke (びーすけ). A custom illustration and full video production — rather than a static-art cover — signals that this was treated as a proper release, not a between-streams bonus.
Big Things Around the Corner for Sara Hoshikawa
The timing is no accident. Hoshikawa has her 2nd solo live, “Hoshikuzu Shining Day -Kimi to Tsumugu Hoshi no Kiseki-“, scheduled for February 7, 2027 at Kanadevia Hall, and her 2nd mini album Stella Note drops November 25, 2026. A passion-project cover landing weeks before a new album and a solo hall show? That’s an artist warming up in public. Set a reminder for the premiere — this one’s worth catching live.
