IRyS of hololive English drops the 3D MV for MUSE, a track from her debut album DANGERyS, and it’s one of those releases where the concept, the performer, and the execution all click into place at once. Composed and arranged by mifumei, with lyrics by Steph and an MV directed by KANAURU, MUSE leans directly into what IRyS is — a vsinger, a voice, a source of creative inspiration — and turns it into the subject of the song itself.

What ‘MUSE’ Sounds Like

mifumei builds the track around a contrast that the title sets up immediately: there’s something classical and almost reverent in the melodic structure, but the production underneath it is sleek and modern. The arrangement doesn’t rush. It opens with space and lets IRyS’s voice occupy it before the fuller production comes in, and that choice pays off — by the time the chorus lands, it carries real weight.

The song has an anthemic quality without being a straightforward anthem. It’s more contemplative than triumphant, which suits the subject matter. A muse isn’t loud. She pulls people toward something. The track understands that.

IRyS’s Vocal Performance on MUSE

IRyS has a voice that sits in a distinctive place — there’s a warmth to it, a slight weight in the lower register, that makes her immediately recognisable. MUSE plays to that identity rather than testing its limits. The verses are sung with restraint and confidence, and the chorus opens up naturally without forcing anything. It’s a performance that trusts the material, and the material trusts her back.

Lyricist Steph — who also wrote holoAdvent’s “Genesis” with mifumei — gives IRyS lines that feel personal without being overly on-the-nose. The muse concept is handled with enough subtlety that it lands as genuine emotion rather than a theme park version of the idea.

KANAURU’s MV and Why the Production Package Matters

KANAURU is one of the most recognisable MV directors working in the hololive space, and the 3D MV for MUSE shows why that credit carries weight. The visual language matches the song’s tone — cinematic, considered, built to make IRyS look like exactly what the song says she is. The choreography by まりやん (Mariyan) and the storyboard and concept work by Asteroid Music give the MV a coherence that goes beyond a performance clip. It’s a visual argument for the song’s thesis.

mifumei, Steph, and a Growing hololive EN Partnership

The mifumei and Steph combination is becoming a notable one in the hololive English music space. mifumei composed “Genesis” for hololive English -Advent- — the kick-off track for Advent’s 2nd Anniversary — with Steph on lyrics for that release too. Two collaborations in relatively quick succession, both for major hololive EN productions, suggests this is a creative partnership with real momentum. MUSE is the stronger of the two in terms of fit — the material suits IRyS in a way that a group anthem can’t quite achieve by design.

mifumei is a Japanese composer and DJ with a background in game music, including years at Bandai Namco Studio, before moving into broader music production work. That game music foundation shows in how precisely the track is structured — every section earns its place, nothing outstays its welcome.

DANGERyS and What This Release Represents

MUSE is part of IRyS’s debut album DANGERyS, available now on streaming. For an artist who debuted as hololive’s first vsinger — a role defined entirely by music rather than gaming content — a debut album is a significant statement. MUSE as a standalone MV release is the right track to spotlight: it’s the one that most directly addresses what IRyS is and why she exists in this space. A song called MUSE, sung by the vsinger, directed by KANAURU. It’s not subtle, but it doesn’t need to be.

This is one of the better productions to come out of the DANGERyS album cycle so far. Give it a proper listen.
