Kaoru Umemiya

Kaoru Umemiya is a member of the Ishiyama High School's Red Tails, a group of strong female students who are entrusted with the protection of Ishiyama High's female students.

Appearance
She is a short haired girl wearing a standard school uniform and like Nene Ōmori, she is always seen wearing a white coat. She is also notably the tallest member of the Red Tails.

Personality
She is usually the most silent and reserved member of the group and seems to keep her composure in most situations and is usually the most serious of the group, a trait she shares with fellow Red Tail Ryōko Asuka. Unlike the other Red Tails, she and Ryōko are the only ones to not have befriended the 3 male members of the Tōhōshinki and their subordinates and are still the only ones to hold a negative view on men, however she did show some regret at not having been able to join in on the fun during the War Games incident. Like the rest of the Red Tails, she thinks little of Furuichi, believing him a pervert and a pedophile.
