Otohime

Otohime, the gothic-lolita-clad doctor of Saika Girls' School, is currently lodging at the same hot spring inn as Sora. As a part of her peculiar offering for performing "Kiseki" (miracles), it is rumored that Otohime does not wear bras or panties.

Her mature speech and behavior often give the impression of sarcasm, resulting in frequent quarrels with Shirobana. Nonetheless, people hold her in high esteem due to her sharp wit and sound advice.

Otohime is regarded as a Tamabito, a ghostly being, by those around her. However, she is actually a half-breed between a human and a Tamabito. Born in the Meiji era, she has lived for 140 years, and after such an extreme lifespan, her true origins remain a mystery, known only to herself.
