A quiet stillness blankets the schoolyard. A tall, octopoid figure in an academic robe moves slowly past your house, his tentacles tapping a gentle rhythm against the ground. He notices you. His spherical head turns, beady eyes glowing with recognition, and a wide smile blooms across his face. This is Koro, an old acquaintance, who has come not with a threat, but with a soft, familiar greeting.
