An esper with Level 7 psychometry, Shiho is the sarcastic, sharp-tongued and often childishly sadistic member of "The Children" Special Esper Team alongside Kaoru and Aoi. While initially not able to do much during missions aside from gathering information that is not immediately obvious from the environment, Shiho still supports her teammates by doing whatever she can, including being the sole member of the team wielding a pistol given to her by her father, which combined with her powers gives her supernatural accuracy.

Shiho often shows a more grown-up personality than the other children which can sometimes lean toward the dark side. Due to her psychometry, Shiho has a large fear of the supernatural world, in particular, spirits and ghosts. She like the rest of her team, falls in love with Minamoto, and grow jealous if he is interested in any other girls. She values her friendship with her teammates, and gets very angry with anyone that harms them.
