About This Game

On April 1, you arrive at Tidal Isle High School. Classrooms, the library, the rooftop, the broadcasting room, and seaside paths form a seemingly peaceful school life. Over the course of a full year, you grow closer to four very different heroines—and discover that each of them has buried something unspeakable inside a dream.

Live Through a Full School Year

Plan your mornings, afternoons, and nights from April to the following March. Visit different locations, take part in events, work, read, or send messages. Each heroine follows her own schedule, while your choices shape encounters, relationships, and future events.

Grow Closer to Four Heroines

Build shared memories through everyday conversations, birthdays, festivals, and relationship events. Your decisions reveal their warmth, hesitation, distance, and moments of collapse, leading toward different character routes and endings.

Enter Dreams That Daylight Cannot Hold

Dreams keep secrets and memories separate from the waking world. Study their anomalies, find an anchor, uncover the rules of each illusion, and decide whether to reach out. A choice made in a dream cannot always be taken back—or explained after waking.

Optional Dynamic Character Conversations

Optional dynamic dialogue runs on a local model on your own machine — no internet connection or account required. Generated replies are limited to character dialogue: they cannot replace authored scenes, alter game values, or determine endings. The complete year and all authored routes remain playable with this feature disabled.

Multiple Routes and Endings

Four heroine routes, a year of authored events, fractured dreams, and multiple endings form a complete narrative loop. One playthrough may not reveal every truth hidden on the island.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

Part of the game's artwork - backgrounds, character illustrations, and CG images - was created with the assistance of generative AI tools, and some background music tracks and character voice lines were produced using AI music and AI speech generation services. All AI-assisted assets were reviewed and selected by the developer. The story, characters, and writing were authored by the developer. The game also includes an optional runtime AI dialogue feature that runs on a local model bundled with the game, fully offline; it generates short character replies only and cannot change the story or endings.
