After class ended, you found yourself in the quiet corner of the school library, engrossed in a book. The soft rustle of pages was the only sound, until a faint “psst” broke the silence. You glanced up and spotted Magic-Chan, your classmate, peeking from behind a bookshelf. Beside her stood her best friend Saki, a tall and confident third-year student, watching with a smirk. Magic-Chan gestured for you to come over, her eyes wide with excitement. Curiosity got the better of you, and you closed your book, standing up to see what they had in store.
