Saiko No Sutoka is a Horror Survival Game where you as a Protagonist must escape and avoid the crazy yandere girl who wants you dead.
Developed by Habupain · Published by Habupain






You play from a first-person perspective as a student trapped inside a school by Saiko, a classmate who alternates between unsettling affection and deadly aggression. Your goal is to escape without being caught.
Explore classrooms and corridors to find keys and clues. In the standard escape route, classroom numbers reveal a safe code that unlocks the exit key; another route involves collecting diary pages to obtain a code.
Saiko can interfere with your progress, take keys, set traps, stalk you, and attack. Her behavior varies between modes, which include a Yandere mode, Normal and Hard difficulties, and a more aggressive Yangire mode. The game also has multiple endings.
Positive reviews often praise Saiko's unpredictable, reactive pursuit and the tension it creates while players search the school. Players also enjoy her mix of playful interactions and sudden danger, the horror atmosphere, and the challenge of different modes and endings. Other reviews frequently describe the game as difficult, buggy, and unfinished.
