Author’s Note

This visual novel is designed to deliver the most realistic depiction of incestuous romance possible. The focus remains on the romantic love story between the protagonist and his sister, and the game intentionally avoids harem-style content.

We hope the narrative will feel engaging alongside the adult content, so you can experience a “pure and innocent” style of story presentation.

During gameplay, your choices will influence your lover’s behavior and the overall direction of your relationship. We genuinely hope you enjoy the game and look forward to what comes next.

Please note: In the early stages, the graphics may look slightly rough, since development is ongoing. If you’re interested in the story, please keep playing—graphics are expected to improve as the project progresses.

Wishing you a great day, friend.
