Getsuei Gakuen -kou-

The game centers on the protagonist Kou, who has just transferred to Getsuei Gakuen High School, and on his first night after transferring, he encounters mysterious hostile creatures that roam the night – “Hazards”. He survives the ordeal after being saved by a female student at the same high school, but just when he thought he was safe, the girl turns around and kills him… or so he thought.

The next moment, he wakes up on his bed, unharmed. Confused by the nighttime encounter, he heads to school, only to realize that “today” is the “first” day of his transfer… again.
