Dasshutsu Adventure – Kyuukousha no Shoujo

A silent classroom inside an old school building sets the story in motion as the main character finds a girl sitting alone beside a broken emergency broadcast speaker. The windows are sealed, the hallways are empty, and strange messages appear on old posters stuck to the walls. The girl says the school changed after the last drill, and no one has been able to leave since. Moving out of the room reveals hallways filled with locked doors, scattered notes, and clues about why the school froze in this strange state.

Gameplay focuses on searching classrooms, opening drawers, and checking objects that hide small hints. Some puzzles involve matching symbols found on chalkboards, using keys discovered in storage rooms, or arranging items left behind by other students. Touching certain objects reveals short messages that point toward hidden compartments or unusual mechanisms in the building. A few scenes require quick decisions to avoid danger, but most of the progress comes from steady observation.

New floors open as puzzles are completed, showing science labs, music rooms, and storage wings with different types of challenges. Some rooms contain machines that activate only with specific items gathered earlier. Others hide clues in sound, lighting, or small repeating patterns. The girl appears at key moments, giving brief hints or reacting to changes in the environment. More strange details appear the deeper the exploration goes, revealing what happened during the drill and why the school remains trapped in this state.
