The first Disciplinary Squad:
It was formed when an army attacked Kamikura Island and most of the Sekirei still were embryos and eggs. Members were #1 to #5 and they easily defeated the international army protecting all unborn Sekireis. They disbanded for various reasons, Matsu stealing the Jinki #8, Miya because of her husband and Kazehana because of her rejected love to the director. Mutsu was refered to as a Sekirei which is hard to control.

The second Disciplinary Squad:
Not much is known about the second Disciplinary Squad. In a flashback it is revealed that Karasuba and Yume were fighting in order to save Musubi when she was still a baby. In this incident Karasuba killed a huge amount of soldiers stating to Yume how weak they were, saying she only killed them because Yume haven't been here.

The third Disciplinary Squad:
This is the currently active formation. They are known to be ruthless and even killing Ashikabis which is forbidden by the rules of the Sekirei Plan. They all seem to be rotten and to enjoy killing. They are under the command of MBI hunting down escapies but also terminate other Sekirei if they are in the mood to do so. Yume when taking control over Musubi's body asked since when the Disciplinary Squad attacks other Sekirei. Now all members are winged by an Ashikabi named Natsuo Ichinomi.
