Sorawo Kamikoshi is a timid and antisocial university student with a knack for exploring ruins. Although she is well-versed in urban legends, she expresses dislike for what she considers "fake rumors" — as opposed to "true ghost stories" that are primary accounts of witnesses to paranormal events.

Sorawo found the "Otherside" by chance and initially planned to make it her secret retreat, until she met Toriko there. Together, they explore the Otherside, uncovering its mysteries and collecting artifacts to sell to Kozakura for research. After a confrontation with a Kunekune from the Otherside, Sorawo's right eye is left permanently blue and gains the ability to see the Otherside beings' "core." She usually wears a brown contact lens in order to not draw attention to it. It appears that she is more susceptible to being manipulated by illusion-type apparitions, usually requiring Toriko to snap her out of the hypnotic trance she's put in.
