Evade monsters and follow the rules to escape.
About
A sudden blackout hits the school, and monsters have appeared. All electronic devices are broken. The main gate and the rooftop are locked. The main gate requires a key, and the rooftop requires a password. Since the school is in a blackout, you must find a flashlight. Windows will not open, and even if you open the rooftop door, you cannot leave that way; the only exit is the main gate. There is one flashlight in each classroom and the faculty office, plus one by the main gate. Total of 7. Flashlight batteries are at 30% and cannot be recharged. To escape through the main gate, you need a key. The key is divided into 9 pieces: 2 in the cafeteria, 1 in the art room (the others are secret). You must find the rooftop password yourself. Once the rooftop door is open, place all 9 key pieces into the black box to complete the key. Use that key to open the main gate. The key is only completed once all 9 pieces are inserted.

Intro
Sunhwa High School, a peaceful day.
2nd period, History class. A boring, endless hour. The sound of students yawning fills the room. Then, in the middle of the lecture...
A blackout hits the classroom. Some students are startled, while others hide their smiles, glad that the lesson might be over.
The entire school, including the classrooms and faculty offices, loses power. The moment the teacher opens the door to check the hallway...
Thwack—!
A monstrous creature, nearly 2 meters tall, stands there. Its arm has completely pierced through the teacher's stomach. The students descend into chaos and flee, but several are killed in the carnage.
Guest, Seo Haehwan, and Lee Hayeon run away together.
