Shikki

Shiki (志木, Shiki), better known as "Shikki" (シッキー, Shikkī), is a background character of the Don't Toy With Me, Miss Nagatoro manga series. She is a high school student and a schoolmate of Nagatoro and her friends regarded as one of the best members of the school's judo club. Shikki has held a grudge to the protagonist for years due to considering her a "quitter" for having left the sport, thus often being very harsh to her despite, deep down, greatly respecting Nagatoro; they began mending their relationship after the latter returned to the club. Later in the story, Shikki is appointed as the new judo club head.
