Sekirei (セキレイ, lit. Wagtail) is a Japanese manga series by Sakurako Gokurakuin. The manga was serialized in Square Enix's seinen magazine Young Gangan between December 2004 and August 2015. A sequel to the manga began serialization in the same magazine in May 2017. An anime adaptation produced by Seven Arcs and directed by Keizō Kusakawa aired in Japan between July and September 2008, and a second season aired between July and September 2010. Both seasons were licensed in North America by Funimation, until their license expired in 2017. The central character of the series is Minato Sahashi, a ronin who has failed his college entrance examinations two years in a row. His life changes, however, when he meets several girls with special powers called "Sekirei" and is dragged into a battle to possibly decide the fate of the world.


In Tokyo, known as Shinto Teito (新東帝都, Shintō Teito, "New Eastern Imperial Capital"), in 2020, 19-year-old Minato Sahashi is extremely intelligent, yet due to his major lack of self-confidence has failed the college entrance exam twice.

The same day of his second failure, Minato meets a girl named Musubi, who literally falls out of the sky on top of him. Minato soon learns that she is a "Sekirei", and she chooses him as her "Ashikabi", one of the mysterious set of humans that have the genetic trait and can make a contract by kissing the Sekirei; this binds the Sekirei to the Ashikabi and allows them to use their full power in elimination battles with other Sekirei. Made up of 108 cute girls, attractive buxom women and bishōnen, the Sekirei battle in a competition known as the "Sekirei Plan" organized by Hiroto Minaka, the chairman and founder of the mysterious and powerful MBI Corporation.

Minato quickly learns that being the partner of a Sekirei is not all fun and games, especially when five other Sekirei choose him as their Ashikabi, each also forming a contract/bond with him. Now Minato must find a way to survive both the life-threatening battles of the Sekirei Plan and his partners' fierce competition for him.



Sekirei (鶺鴒, lit. Wagtail) are superpowered beings with a different genetic code that may react to a human's, and who have been "modified" to be able to exist on Earth. The Sekirei spaceship crashed on Earth in 1999 on Kamikura Island (神座島, Kamikura-jima), and was found by two students, Hiroto Minaka (future MBI chairman) and Takami Sahashi (future MBI head researcher and Minato's mother). On board, the pair had found 108 life-forms, described as "One pillar and 107 baby birds".[5][6]

  • The first of them (a pillar, shown as #00,[7] later renumbered and known as #01 Miya) 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.[8] All of the Sekirei had been given adjustments for the Sekirei Plan, especially the Single Numbers. The adjustments had been used not only for enabling them to exist on Earth but also for making them stronger and for controlling and strengthening their power. Each Sekirei has a Norito (祝詞, lit. "Incantations"), a unique ability that allows them to perform powerful attacks. In order to use the Norito, a Sekirei must engage in mucosal contact with (i.e., be kissed by) their Ashikabi[9] prior to reciting it. Sekirei that are under the same Ashikabi can also merge their powers/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 DNA that enable them to empower the Sekirei destined to serve them. Through mucosal contact (kissing) between a Sekirei and its Ashikabi, a Sekirei without wings can become a "winged" or "emerged" Sekirei. Unlike Sekirei, who are mostly buxom women or handsome young men, Ashikabi can be quite innocuous as they can appear in any gender, age and even status. In the series, 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 battle escalates, five Ashikabi in particular, emerged as the favorites to win the Sekirei Fight, each having winged at least three Sekirei. One of them is Natsuo Ichinomi, an employee of MBI who is also the leader of the Disciplinary Squad, while each one of the other four controls a different area in the city; Minato Sahashi in the North, Hayato Mikogami in the South, Izumi Higa in the East and Nishi Sanada in the West. If an Ashikabi dies or is killed, all Sekirei winged by him or her will also perish.


Jinki (神器, lit. "God instrument"),[10] are eight mysterious artifacts numbered from #1 to #8,[11] also found on the Sekirei spaceship. If all eight of them are gathered, it is possible that they can be used to terminate all Sekirei if the wielder desires.[12] Upon all Sekirei being winged, Minaka puts all Jinki in MBI's 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 Battle by the end of the stage.

Sekirei Plan[edit]

The Sekirei Plan (鶺鴒計画, Sekirei Keikaku), known to Minaka and others as the "Game", is a competition in which the Sekirei and their Ashikabi must fight for survival until the last one of each remains. The true purpose of the plan is unknown, but it is implied to be sinister to some extent. The second anime season ended with the Second Stage completed, but before the Third Stage matches begin.

  • First Stage: The Sekirei are adjusted and released in Tokyo. Thereafter, they must find Ashikabi in order to be winged. This stage ends when 90% of the Sekirei have been winged.
  • Second Stage: Teito becomes a closed city and no Sekirei or Ashikabi can leave. The Ashikabi must then wing the remaining unwinged Sekirei, and every Ashikabi and their Sekirei must defeat at least one Sekirei.
  • Third Stage: A series of battle royales between Ashikabi for possession of the Jinki. Only the Ashikabi who secure at least one of the Jinki until the end of this stage are eligible to advance.
  • Final stage: The remaining Ashikabi are brought with their Sekirei to Kamikura Island and must fight among each other for the right to ascend to the Heavenly Palace Kouten and fight the pillar for the prize awaiting the ultimate winner of the Sekirei Battle.
