A high-difficulty strategy RPG where a peaceful daytime school life intersects with a deadly nighttime death game. The time limit is a mere 10 days, spanning from August 1st to August 10th in-game! Prepare yourself by exploring the town during the limited daytime, and dive into tense battles at night where strategic grid movement and split-second decisions mean the difference between life and death! Under the extreme tension of "Die twice and it's an instant Game Over," navigate through branching multi-endings and let your choices lead you to the truth on the 10th day!
