Tokyo, 1998. The rain never stops, the millennium is coming, and in the corner of an apartment, a girl is waiting for the world to end. Japanese indie development and publishing label C#4R4CT3R released the first public demo of its lo-fi psycho-thriller romance adventure Rain98 on Steam on October 17.
The demo was announced and released alongside the game’s appearance at The MIX Fall Game Showcase 2026, held on October 16 North American time.
Rain98 is a narrative-driven adventure that blends lo-fi atmosphere with psychological thriller and romance. With the demo now out, the game is setting out to build a global audience ahead of a full Steam release targeted for 2027.

Tokyo, 1998: Reina Amehara, the Girl Waiting for the End
The setting is a perpetually rain-soaked Tokyo in 1998, steeped in end-of-the-century mood.
The protagonist, having slipped back in time by chance, meets Reina Amehara, a mysterious girl waiting in the corner of an apartment for the world to end. Brought to life by rising voice actor Rio Tsuchiya, Reina and the protagonist begin preparing a strange “ritual” to stop the world’s destruction.
This is no ordinary romance. Players work part-time jobs to earn money and take care of Reina, all while keeping up with her unpredictable moods. Upset her, and terrible endings await.
The game recreates a hazy 1998 Tokyo through ringing payphones, game-center noise, and Shibuya neon bleeding in the rain. It’s also packed with small, charming minigames, from pulling capsule toys to making bead crafts on dates with Reina.
Where Reality and Delusion Break Down
The quiet daily life the two share soon begins to crack. The protagonist’s memories fade like fog, unexplained visions cloud his sight, and Reina herself, hiding an enormous secret, tightens her grip on the player.
It’s a classic psychological thriller unraveling, with the line between reality and delusion collapsing. The dark, seductive mood is amplified by a lo-fi soundtrack of gentle jazz piano and rain.
The developers’ near-obsessive craftsmanship around Reina stands out. More than 1,500 illustrations were created just to depict her daily life, from flipping absently through a magazine on the sofa to exhaling cigarette smoke alone, bringing every moment of her to life on screen.
The full game, coming in 2027, will offer about 10 hours of play per run and more than 100 minigames.
A 3-Hour Demo, With Saves Carrying Over
The demo covers the prologue, Chapter 1, and the first half of Chapter 2, totaling about three hours. The rest of Chapter 2 will be added to the demo in a future update. Save data from the demo is being prepared to carry over to the full game.
From PAX East “Best of Show” to BIC 2026
Rain98’s distinctive aura has already won over international audiences. It was named “Best of Show” at PAX East 2026 and has also appeared at BitSummit, Bilibili World, and ChinaJoy, establishing it as a rising indie prospect.
Outlet Boss Rush praised it as a genuinely fresh experience unlike anything it had played before. The game also has a strong connection with Korean players: at BIC 2026 in Busan in August, its blend of fin-de-siècle retro mood and suffocating psychological tension impressed attendees.
The biggest news for Korean fans is the developer’s response to their support. Answering enthusiastic encouragement and requests from Korean indie fans, the Steam demo now includes full Korean subtitles and interface.
The voice cast also features Rio Tsuchiya, who won fans as the cynical Madoka Higuchi in THE IDOLM@STER SHINY COLORS, and veteran voice actress Mamiko Noto, celebrated for her distinctive voice as Sawako Kuronuma in Kimi ni Todoke: From Me to You, making it a strong draw for anime and subculture fans.
Who This Is For
Strong fit for: fans of psychological thriller romances and unsettling visual-novel-style narratives; anyone drawn to late-’90s Japanese nostalgia, lo-fi aesthetics, and rainy-city atmosphere; players who enjoy character-focused games with deep illustration work; anime and voice-acting fans; Korean players, with Korean supported from the demo onward.
Cautious fit for: players sensitive to psychological horror, manipulative relationship dynamics, or dark endings; the romance is deliberately unsettling.
Less ideal for: those looking for a straightforward, wholesome dating sim.
What to Watch For
The key question is how well the warm, minigame-filled daily life and the creeping psychological thriller balance over a full 10-hour run, and how many endings the mood system produces. The remaining Chapter 2 update and save carryover should give demo players good reason to stick around before 2027.
The Takeaway
Rain98 is one of the most atmospheric indie projects in development: a rain-soaked 1998 Tokyo, a girl waiting for the apocalypse, 1,500+ illustrations devoted to her every moment, and a romance that curdles into a psychological thriller. With PAX East’s “Best of Show,” a three-hour demo, a strong voice cast, and Korean support already in place, it has every chance of becoming a cult favorite when it fully releases in 2027.
Demo: available now on Steam. Full release: 2027.
