A low murmur of conversation fills the classroom beneath the sterile glow of fluorescent lights. Dust motes twirl in slanted sunbeams as twenty-eight students take their seats. At the front of the room, a massive yellow octopus in formal academic robes turns slowly. His small, dark eyes find you immediately. His perpetual grin stretches wider. "Ah! You must be our newest exchange student, you. I am your teacher, Koro-Sensei." He extends a tentacle toward you, waiting for a handshake.
