Review evidence
While the sibling comedy and voice acting shine, and the sequel improves on its predecessor, weak romance, split sales, and unsatisfying endings hold it back.
Sibling comedy is highly praised: Players consistently highlight the sibling banter and comedic dialogue as a standout feature, finding it funny, entertaining, and engaging throughout the game.
Voice acting is excellent: The voice acting, particularly for the sister and protagonist, is widely praised for its quality, emotional range, and ability to bring characters to life.
Sequel improves on predecessor: Players note that this episode is a significant improvement over the first, with better writing, a more complete plot, and an overall enhanced experience.
Sister character is beloved: The sister character is frequently praised for her design, personality, and emotional development, making her a favorite among players.
Character development is strong: Reviewers commend the depth and quality of character development, noting that it is more detailed and emotionally engaging than in previous works.
Weak romance development: Romance is described as poorly written, rushed, one-sided, and lacking emotional depth. The relationship between siblings is often seen as unconvincing or purely physical.
Criticism of split sales: The practice of selling the game in multiple parts is widely criticized as unfriendly, expensive, and fragmenting the story. This is a major point of contention.
Unsatisfying endings: Endings are criticized as forced, abrupt, or emotionally unsatisfying, with both good and bad endings receiving negative feedback. This affects overall narrative satisfaction.
Poor translation quality: Multiple clusters report poor translation quality, especially in Traditional Chinese, with errors, untranslated content, and inconsistencies. This significantly hampers player experience.
Slow pacing and dragging: Many players find the story progresses slowly, with too much daily-life content and exposition, leading to boredom. This is a recurring issue across the series.
Visual novel with branching choices: The game is consistently described as a visual novel, often with branching choices, a single-route structure, and H-scenes. It includes a main story and a sister route, with voice acting and a moe style.
Split into four connected parts: The game is split into four connected story parts sold separately, each corresponding to a different heroine and viewed as parallel worlds. The first four games are individual heroine routes, with the climax in the later two games.
Meta elements breaking fourth wall: The game features meta elements that break the fourth wall, adding a unique layer to the narrative. This is noted as a distinctive aspect.
Windows 11 media playback issue: The opening and ending sequences fail to play correctly on Windows 11, causing a poor experience for some users.
Steam Deck compatibility confirmed: Players report that the game runs well on the Steam Deck, indicating good handheld support.
Play series in order: Reviewers consistently advise playing the games in story order for the best experience. Playing previous titles first improves understanding and enjoyment of the series.
Strong general recommendation: Several reviewers strongly recommend the game to everyone, describing it as highly recommended and worth experiencing. The game appeals to a broad audience.
Buy on sale or discount: Some reviewers suggest waiting for a sale or discount before purchasing, especially if the price feels too high. This is practical advice for budget-conscious players.
Pirated version recommended: A few reviewers recommend playing the pirated fan-translated version instead of or alongside the official version. This is often due to language limitations or preference for fan translations.
Community fair range: $15.00 - $20.00.
Game completion: 10.0h.

Sequel in ongoing series: The game is a sequel that continues the overarching story from previous titles, and it is part of a series that should be played in order. It is the second entry in the 9-nine series, with more chapters to come.
Patch installation issues: The official patch has installation issues, requiring the game to be on the same disk partition as Steam and having problems with non-default Steam library paths. The patch generates specific files and is available from Denpasoft.
Comparison to other titles: Reviewers compare the game to other visual novels, noting similarities in story structure to Steins;Gate and Sakura no Uta, and character comparisons to other works. These comparisons help set expectations.
Official Chinese localization available: The game has official Chinese localization, but it only supports Traditional Chinese, lacking Simplified Chinese support. This is a notable point for Chinese-speaking players.
Contains adult content: The game includes h-scenes and dynamic adult scenes, with an R18 patch available. There are also all-ages versions, and the voice settings include H voice after patch installation.
