Sanae Higashihongan

Sanae Higashihongan is the spirited ghost girl who has claimed Room 106 of Corona House as her own. Originally lingering there in hopes of reuniting with her long-absent parents, she made it her mission to drive away every would-be tenant—until she met her match in protagonist Kotaro Satomi, sparking an all-out battle for the room. Bubbly, innocent, and irresistibly clingy, she delights in pulling pranks on those around her. Yet her true nature holds a surprising secret: she is not a conventional ghost, but rather a "living spirit" whose overwhelming spiritual power caused her soul to separate from her physical body. Once reunited with her corporeal self, she blossoms into an indispensable and dependable ally within the Satomi Knight Corps.
