Note written 2026-09-15; the live figures above take precedence over any numbers in it.

Sumire is a 4-hour narrative adventure about a girl's final day, told through poetic vignettes and memory fragments.

This 2021 title maintains exceptional positive sentiment (95%+) and steady organic review flow despite zero current marketing, suggesting quiet but devoted player affinity. The indie-published profile, modest ask price, and complete localization across five languages make it a low-friction acquisition candidate for publishers seeking catalog depth in the adventure genre, particularly in Asian markets where localized reviews cluster. However, the developer studio appears inactive, which limits ongoing support expectations and narrows the play to rights acquisition rather than partnership. Most realistic play: acquisition.

• Risk: Developer studio status listed as inactive; rights chain and backend support infrastructure require due diligence before acquisition.
• Risk: Current residual revenue sits at solid three-figure monthly range, implying a small but stable owner base; meaningful uplift would require active marketing investment or platform placement.
• Risk: Build age of 53 months means potential compatibility drift with newer Steam runtime and accessibility standards; QA pass advisable pre-acquisition.
