Evaluation

Sisters: Last Day of Summer is a fully-animated visual novel that launched on June 3, 2024. The game was released as a complete, self-contained story with no post-launch content roadmap, season pass, or announced expansions. Since launch, the developer's only post-launch activity has been maintenance: a Chinese localization update (June 6, 2025) and an accompanying bug-fix patch (June 10, 2025). Neither of these updates introduced new story content or announced future expansions — they represent standard localization and compatibility support for an existing release. There are no unreleased DLC items on the store, no developer statements about upcoming content, and no history of major content drops beyond the initial launch. The game appears to have shipped as a finished product.
