San Otonashi (音無 燦 Otonashi San?) is a graduate of Yōkai Academy and the former Newspaper Club president. She rarely speaks, which because her powers lay in her voice, and carries around a sketchbook to write on instead of talking to keep others safe. She was the one who taught Ginei Morioka how to use a camera and stopped him from fighting everyone in his first year. She now lives with Marin Kawamoto who found her after she had nowhere to go.
