Kasumi Miwa

A second-year student at the Kyoto Metropolitan Curse Technical College and a Grade 3 sorcerer who specializes in swordsmanship.

Acts like a secretary for Rokuganji, and takes a stern attitude towards Gojou when he arrives unannounced at Rokuganji's place. However, she is actually a fan of Gojou, and was thrilled to see him up close, even taking pictures with him. Among the students at the Kyoto school, she is sensible and not enthusiastic about the assassination of Itadori. She has two younger brothers and lives in poverty, hoping to advance in rank to become independent. She was scouted by the highest master of the Shin-Inryu at her part-time job in her first year of middle school and enrolled as if being swept along.

Her weapon is a sword, and she is a practitioner of Shin-Inryu. Her simple domain automatically intercepts anyone who enters within a radius of 2.21 meters. She uses the Shin-Inryu's fastest technique, "Battou," which involves accelerating the sword within its sheath covered with cursed energy, specialized for frontal attacks.

According to the author, Miwa's name is derived from being a fan.

During the Shibuya Incident, she swung her sword with all her might at Kusozu, ready to never wield a sword again, but it was stopped with one hand. In the Death Painting Womb, she participates from the Sendai Barrier as a messenger to Otokotsu.
