Smile! Sotomura-san

Katakura Tsumuri is the school nurse who runs the high school’s infirmary… which is good, because she’s the one who needs to make use of it the most.

Mukai Sachi is extremely unlucky. Stubbed toes, lost items, bird poop... it all happens to her. Her most unfortunate problem, though, is Gokurakuin Misako, the only member of the Occult Research Society. Misako is an honors student, beautiful, very strange, and friendless. She is interested in Sachi's "power" because she wants strange, unexplainable things to happen to herself, too.
