Rain98 music and official trailers

Rain98's featured song has a vocal version sung by Rio Tsuchiya, Reina's voice actor, and the official trailers — the Demo Release Trailer and the Opening Movie — are on the studio's YouTube channel.
Rain98's sound is half its identity: Lo-Fi music layered over the sound of rain, with a vocal theme performed by the same actor who plays Reina. Here is what the studio has actually released, and where to hear it.
The featured song
The game's signature track has two versions. The original was an instrumental, used in earlier trailers. The vocal version was revealed in the trailer the studio published when it refreshed the Steam store page — and it is performed by Rio Tsuchiya, the voice actor for Reina Amehara.
That detail came with an explanation: the refreshed trailer was built to express the game's "decadent and nostalgic" world more vividly, with new animation and stills, and the vocal theme was the centrepiece of the reveal.
| Track / video | What it is |
|---|---|
| Featured song (vocal) | The theme, sung by Rio Tsuchiya |
| Featured song (instrumental) | The earlier version, used before the vocal reveal |
| Rain and Lo-Fi bed | The continuous ambience underneath every scene |
The official trailers
Three pieces of official footage matter if you are following the game:
- Rain98 – Demo Release Trailer — the launch trailer for the free demo, published with the 16 October 2026 release: watch it.
- Rain98 – Opening Movie — the game's opening sequence, separately published: watch it.
- The MIX Fall Game Showcase 2026 reveal — the new trailer debuted at the showcase before the demo went live.
The studio's YouTube channel is @csharp4r4ct3r, and its X account posts the same videos with announcements.
Why the soundtrack stands out
Reviews of the demo mention the audio more than almost anything else. The repeated description is Lo-Fi: soft, low-frequency, sitting under dialogue rather than competing with it, with rain as a permanent layer. The store page's own feature bullet calls it out — Lo-Fi music with the sound of rain, comfortable on the surface with something unsettled underneath.
One practical note from players: parts of the demo's audio deliberately sound processed or reversed, and that is the genre at work, not a broken file. If you are checking your setup, the official trailers use the same treatment, so comparing the two is a quick sanity check.

Buying the music
There is no soundtrack release, no Steam soundtrack DLC and no store listing for the music at the time of checking — the demo's own news feed covers the demo, the trailer and the delay, and nothing else. If a soundtrack is announced later it would most likely appear as a Steam DLC, but nothing of the sort has been published.
