His weapon of choice is a multipurpose tool with various types of blades, and is also highly skilled at disguising himself as other people.

Osaragi

Voiced by: Saori Hayami^[5] (Japanese); Xanthe Huynh^[4] (English)

Osaragi (大佛) is the youngest member of the Order who only recently joined. Shishiba serves as a sort of mentor to her.

She has a great love for food, especially snacks. Her weapon of choice is a large circular saw.

Hyo

Voiced by: Hiroki Yasumoto^[6] (Japanese); Imari Williams^[4] (English)

Takamura

Voiced by: Hōchū Ōtsuka^[6] (Japanese); Keythe Farley^{Ep. 12 credits} (English)

Takamura (篁), the most formidable assassin in the Japan Assassin Association (JAA), appears as a frail, lethargic old man yet wields a katana with superhuman speed and precision.

Kanaguri

Voiced by: Satoshi Hino^[7]

Kanaguri (京) is a member of the Order who secretly works for X. He is an eccentric movie director famous for movies about assassins; his passion is so great he will unhesitatingly kill anyone who insults movies. He has no particular loyalty towards X, only following him so he may create a movie about a battle between X and the JAA, with no care as to who wins. His weapon of choice is a bladed clapperboard and a heat-ray camera, which he also uses to help visualize his fighting as action choreography.

Kamihate

Kamihate (上終) is a member of the Order, who is recognized as the greatest sniper in JAA history. Extremely unsociable and preferring not to interact with associates face-to-face, Kamihate is a shut-in, whose face not even the other Order members have seen. When forced to collaborate, Kamihate goes so far as to have a fellow Order member carry a hiragana chart on a paper so that, if the sniper wishes to say something, he can simply shoot at the corresponding characters from afar to formulate messages.

Oki

Oki (沖) is the current leader of the Order and a stickler for the rules, who was overseas for an unspecified assignment, until he return to Japan following Uzuki's assault on the JAA museum.

Kindaka (キンダカ) is the co-founder of the Order alongside Satoru Yotsumura, who usually handled the disposal of problem students from the JCC. After Sakamoto, Rion, Nagumo and Uzuki are sent his way, he is impressed by their skills and recruits them for a special mission, during which Uzuki reveals himself as the enemy and puts him in a coma.

She joins the JCC for information on Rion's whereabouts, and joins with Sakamoto, Shin, and Natsuki to locate the student database.

After her death, Uzuki's guilt manifests as a subconscious persona of Rion, who acts as Kei's protector in combat.

Along with her longtime friend and classmate Byodo, she has been at the JCC the longest as an instructor, even teaching during Sakamoto's time there.
