Umeko Tanaka

Umeko Tanaka, also known as System, is a supporting character in Inō Battle wa Nichijō-kei no Naka de. She was created by the F organization to break the balance of the Fairy War, but later became a member of Hajime Kiryū's clique. Her ability called White Rulebook, allows her to use any power the situation calls for. When Umeko first was introduced, she was seen having red eyes and long, messy, dark purple hair and wearing a light green crop top along with short light green trousers. However, after joining Fallen Black, Aki Natsu gave her new clothes and changed her hairstyle. She now has short, light purple hair and she always wears a big dark blue ribbon to style her hair. She also wears a long, black dress with a red ribbon and knee-length stockings and red ballerina shoes. When Umeko first appeared, she was like a doll with a very quiet personality. She only spoke when asked something and always followed her orders silently. However, even though she was an emotionless child, Hitomi Saitō felt she had no malice inside her. After living a month with Hitomi and Hajime, it was noted she had aged mentally. She was very mature and curious of the things around her, finding "daily life" very interesting. And even though she was still quiet, she could speak her own mind and also use difficult and eccentric words, a trait Hitomi noted she gained from Hajime Kiryū.
