Chiyu Jiai (慈じ相あい 千ち優ゆ, Jiai Chiyu?), is a character in The 100 Girlfriends Who Really, Really, Really, Really, Really Love You. She is Rentarou's 35th girlfriend, and a 25-year-old school nurse at Ohananomitsu High School. Rentarou first meets her when he sustains an injury, and visits the infirmary to have it treated. Chiyu usually has a gentle, compassionate bedside manner which reassures the people she treats—however, she tends to get angry at whatever has caused her patient harm, which shows as anger marks on her face and forehead.
