Sekirei (鶺鴒) are extraterrestrial super-powered beings with a genetic code similar to humans. The Sekirei spaceship crashed on Earth in 1999 on Kamikura Island, and was found by students Hiroto Minaka (future MBI chairman), and Takami Sahashi (future MBI head researcher). On board, the pair had found 108 life-forms, described as "One pillar and 107 baby birds".
The first of them (a pillar, shown as #00, later renumbered and known as #01) was an adult.
Eight (later known as #02-09) were embryos, also known as the "Single Numbers".
99 others (later known as #10-108) were fertilized eggs.
The adult and the eight embryos are also known as the "Single Numbers". It is hinted that unwinged Single Numbers are equal or even more powerful than their winged counterparts. All of the Sekirei had undergone adjustments for the "Sekirei Plan", especially the Single Numbers. The adjustments had been undergone not only for making Sekirei stronger, but also for controlling and stabilizing their power. Each Sekirei has a Norito (祝詞, "Incantations"), a unique ability that allows them to perform powerful attacks. In order to use the Norito, a Sekirei must be kissed by an Ashikabi prior to reciting it. Sekirei that are under the same Ashikabi can also merge their techniques in order to create more powerful techniques. This puts most Ashikabi at a disadvantage, as only a few Ashikabi possess more than one Sekirei.
Ashikabi (葦牙) are humans with unique genes that enable them to empower the Sekirei destined to serve them. Through mucous contact (kissing) between a Sekirei and its Ashikabi, a Sekirei without wings can become a "winged" Sekirei. Unlike Sekirei, who are mostly extremely attractive women or handsome young men, Ashikabi can be quite innocuous as they can appear in any gender, age, and even status. The power of an Ashikabi can be determined not only by the number of Sekirei he or she has in his or her disposal, but by the bond between them. As the Sekirei plan escalates, five Ashikabi will come out on stop to ascend as the favourites to win the Sekirei Plan, each having winged at least three Sekirei. One of them is Natsuo Ichinomi, the leader of the Disciplinary Squad, while each one of the four others control a different area in the city; Minato Sahashi from the North, Hayato Mikogami from the South, Izumi Higa from the East and Nishi Sanada of the West. If an Ashikabi dies, all Sekirei winged by him or her will also perish.
Jinki (神器, "God instrument"), are eight mysterious artifacts numbered from #1 to #8, also found on the Sekirei spaceship. If all eight of them are gathered, it is possible that they can be used to terminate all of the Sekirei if the wielder desires. Upon all Sekirei being winged, the MBI puts all Jinki in their possession as prizes for the matches of the Third Stage, and only the Ashikabi with a Jinki are allowed to keep participating in the Sekirei Fight by the end of the stage.
The Sekirei Plan (鶺鴒計画), known to Minaka, the CEO founder of The Sekirei Plan and MBI and others as the "Game", is a competition in which Sekirei and Ashikabi fight for survival until the last one remains.
-First Stage: The Sekirei are adjusted and released in Tokyo. Thereafter, they must find their Ashikabi for winging. This stage ends when 90% of the Sekirei are winged.
-Second Stage: Tokyo becomes a closed city and no Sekirei or Ashikabi can leave. The Ashikabi must then wing the remaining unwinged Sekirei.
-Third Stage: A series of battle royales between Ashikabi for possession of the Jinki. On the first three matches, each having a single Jinki as a prize, only a few invited Ashikabi participate and the number of Sekirei each can bring is limited. Three other Jinki are offered as prize for a final match to which all Ashikabi are invited. The two remaining Jinki are not offered as prizes, as one of them is stolen from the MBI before the beginning of the First Stage, while the other is awarded to the Disciplinary Squad's Ashikabi for his job helping enforce the Sekirei Plan.
-Final stage: Only the Ashikabi who secure at least one of the Jinki until the end of the Third Stage are eligible to participate with all others disqualified, their Sekirei terminated. Further details are yet to be revealed.
