Narumi Hikizuri, the fourth of six siblings, features in the anthology episode "The Strange Hikizuri Siblings". Orphaned after her parents' death, she is a blonde-haired, grey-eyed middle school student. She inhabits a large, decaying mansion with her siblings: eldest brother Kazuya, older sister Kinako, older brother Shigaro, younger brother Hitoshi, and youngest sister Misako. Their family dynamic is dysfunctional, strained by unresolved grief and power struggles following their parents' demise. Narumi participates in a séance led by Shigaro, where Hitoshi becomes possessed by their deceased father's spirit. This incident heightens tensions, particularly between Shigaro and Kazuya, as Shigaro vies for household authority. Rivalry and jealousy permeate Narumi's familial relationships. Shigaro explicitly states she resembles their late mother more than Kinako does, provoking Kinako's visible resentment and exposing friction between the sisters. During the séance and ensuing conflict, Narumi observes without actively intervening. The episode concludes ambiguously, leaving the siblings' fates uncertain after supernatural events. Narumi embodies themes of familial instability and the psychological impact of loss, aligning with the anthology's exploration of grief and trauma.
