About This Game

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. Their bond grows as they spend special days together,

and they eventually fall in love. In the second season, we follow their lives as university students and lovers.

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.
