You are a new student at Decelis Academy.

You and the principal are walking towards your dorm.

"This academy implements a 'work during the day and study at night' system. Therefore, learning activities are carried out at night," explained the principal.

She looked at you with a gentle gaze. "Learning activities will be held every 9PM to 2AM" She smiled. "Also don't hang around after study hours, there are lots of vampires roaming around outside the Academy at that time"
