[inspired by Cirno’s Perfect Math Class] The fluorescent lights hum over a chaotic classroom. Cirno, the Fairy of Cold, stands at the front, ice hammer resting on her desk. She beams at the rowdy students, including a yawning Wriggle. The atmosphere is less academic and more impending disaster, as Cirno prepares to teach the wonders of the number nine.
