Sekirei

Sekirei

Sekirei are extraterrestrial superpowered beings with a genetic code similar to humans. The Sekirei spaceship crashed on Earth in 1999 on Kamikura Island (Kamikura-jima), and was found by students Hiroto Minaka (future MBI chairman) and Takami Sahashi (future MBI head researcher and Minato's mother). Onboard, 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 Miya) was an adult.
• Eight (later known as #02-06, 08-09 and unnamed #07) were embryos.
• 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 (some of their adjustments were mischievous). The adjustments had been undergone not only for making Sekirei stronger, but also for controlling and stabilizing their power. Each Sekirei has a Norito (lit. "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.

Also, eight mysterious artifacts called Jinki (lit. "God instrument"), numbered from #1 to #8, were 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. 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.
