About OneRoom ―Yui Hanasaka Memorial―

That pure love, that lovey-dovey moment again――A brand-new project from the beloved short anime series "OneRoom" has begun! Introducing "PROJECT OneLeaf," a completely new project where you can once again experience the story of the main heroine, Yui Hanasaka (CV: M・A・O), from the "OneRoom" series in an innovative animated novel game!About the OneRoom Series: The "OneRoom" series is known for its subjective viewpoint, where the viewer themselves is the protagonist, and it features special days spent with the heroines. The series is in an omnibus format and depicts the unique and intimate relationships between the protagonist and the heroines. The first season aired in 2017, the second in 2018, and the third in 2020. With charming characters by popular illustrator Kantoku, stunning animation, a story more profound than one might expect from a short anime, and meticulous attention to fetishistic details, the series became a huge hit.Yui Hanasaka’s Story: Yui Hanasaka is the only heroine to appear in all seasons of the "OneRoom" series. In the first season, she moves to Tokyo for her university entrance exams and meets the protagonist (you), who is her neighbor in the same apartment.

Though they argue and face insecurities, their relationship strengthens. In the third season, the couple faces a major turning point as they transition into working adults.In this game, you can revisit the story from the second season and experience the third season's events.Game Features:・A new type of animated novel game that directly adapts the original anime.

OneRoom -Yui Hanasaka Memorial- is a romance-focused visual novel developed by 株式会社さかさうま工房 and published by Laplacian. Rather than aiming to be a lengthy, choice-driven adventure, it serves as an interactive tribute to one of the most beloved heroines from the OneRoom series. The game faithfully recreates the franchise's signature first-person perspective, allowing players to experience the story as if they are standing directly beside Yui Hanasaka. This design choice reinforces the feeling of intimacy that has always been central to the series, making the experience feel more personal than many traditional visual novels. The narrative revisits memorable moments from Yui's relationship with the protagonist while introducing newly written inner monologues that add greater emotional depth to familiar scenes. Instead of relying on dramatic plot twists or suspense, the story embraces a slower, more heartfelt approach centered on everyday conversations, shared memories, and the quiet progression of a romantic relationship. Players witness Yui's journey from her university days into adulthood, creating a satisfying sense of growth while preserving the gentle atmosphere that fans have co…

For those who have followed the series, this is a great thing to have as it has some extras included in this other than the recap, plus this game adds yui's thought into dialogue, giving it more details as to what she is thinking to make the series complete. But for those who have not followed One Room yet, it is recommended to try checking out the anime first before purchasing this.
