Musubi is the main female protagonist of the story and is the first of Minato's Sekirei.

About Musubi

She met Minato while literally falling out of the sky and was moved by his kindness. This caused her Sekirei Crest to react to him. Due to this, she and Minato became involved in a tournament organized by the MBI Corperation, called Sekirei Plan, which forces them to fight with other Sekirei in the capital in order to protect themselves and the ones they care about.


Musubi is a fair-skinned young woman of average height and slender built. She sports a very developed and curvaceous body with a slim waist and flared hips. She has brown eyes and a brown hair. Her hair is hime-styled; it has short bangs, chin-length strands surrounds her head and framing her face, a single antenna-like strands that hangs just above her head, and hip-length hair at the nape of her neck. Her most noticeable physical trait is her firm and well-endowed chest which is the second-largest of Minato's Sekirei behind Kazehana.

Her normal attire is a white gi with red string decorating it that resemble the traditional clothing worn by the miko with the addition of a short red skirt, mid-calf brown boots, and upper thigh-high white stockings. She also wears a pair of red combat gloves that she only takes off for more social events.

A running gag in the story is about how her clothing always ends up torn and tattered every time she fights, which usually results in a scary speech about manners and modesty from Asama Miya.

Bear Visage.

Musubi is very cheerful and carefree to the point of not having any concept of modesty, as she routinely appears either under dressed or with little or no attempt to cover her exposed breasts. She is very naive but insightful, often saying things she does not understand, and is probably the most 'childish' of Minato's Sekirei, even more so than Kusano. She is very eager when it comes into confronting other Sekirei but never fails to be polite as she would usually ask for permission first before fighting them. Musubi is almost always smiling, even when she is upset or angry.

She develops a inner visage in the form of a ferocious bear that appears behind her whenever she is jealous or angry. The reason given is because she is Miya's disciple. Partly thanks to the inner visage, she has earned the nickname bear (Kuma) given by Tsukiumi,[1] by Benitsubasa (during the third stage after witnessing her visage)[2] and by the fact of this visage being obviously a bear. While Miya uses the Demonic Visage, Musubi uses the "Bear Visage". Another reference of it is when she and Tsukiumi protect both Minato and Kagari after the kiss.

Musubi is very loyal and keeps her word to the point of trying to fulfill it. It has been seen in her battle with Karasuba; to fight and live until they remain the last Sekirei on the battlefield,[3] and Yume; when kidnapped with No.87 Kaho, they swore to Yume that they'd find and be winged by the person they love, and become stronger than anyone else, and when one of them becomes the "last one", the last one would release the Sekirei who had lost their wings back into the freedom of the skies.[4]

Beyond that information, she also has a rivalry with Tsukiumi over who Minato's legal wife is. This rivalry consists mostly of shopping contests to decide who is allowed to sit next to him during meals, which Musubi has never lost once. With the others, she just competes to become closer with her Ashikabi.

Musubi is also known in Izumo Inn for being a glutton, eating large amounts of food and is apparently a capable cook, although she has only ever been seen cooking curry. Miya's nickname for Musubi is "Natural Big Meals Eater".



Yume finds Musubi.

Little is known about Musubi's past except for a few facts: The mysterious Sekirei No. 08 Yume teamed up with Karasuba, rescued Musubi and Kaho[4] when they were children, and saved Musubi's life by Yume giving Musubi her "Tama" (the core which let Sekirei live and use their powers).[5] Years later after Yume's death, Karasuba and Musubi too made a promise that they would be together the last ones standing on the battlefield and that they would fight with the world at stake, like she did with Kaho[4]

Yume notices that Musubi's Tama is destroyed

Musubi also seems to know Takami quite well as she told Minato after the escape plan, that she was adjusted by Takami, which implies that Musubi was residing in one of MBI's facilities before going outside to find an Ashikabi.

Abilities and Power


Musubi charging Kuma-ken.

Her abilities are classified as a fist-type; using raw might and unarmed combat skills to fight.[6] As such, she relies on punch, kick, throw and jump tactics. While initially very unpolished and full of openings, her constant training with Miya has dramatically improved her fighting skills. Karasuba, one of the strongest Sekirei, strongly believes that in time Musubi will far surpass Yume, a Sekirei that considerably outmatched Karasuba herself. During Benitsubasa's second fight against Musubi, Benitsubasa was quickly overpowered to the point it was suggested she use her Norito against Musubi.

In addition to constantly improved combat skills, Musubi has repeatedly demonstrated remarkable strength, speed, and agility. She also showed equally impressive stamina and endurance. Despite taking several hits from Benitsubasa during their first fight, Musubi quickly stood back up unfazed, greatly surprising Benitsubasa.[2]

While most of Musubi's attacks consist of punches and kicks, Musubi has begun to expose pink energy through some of her attacks and a pink aura through her Norito, able to produce energy-based attacks.This energy is the same energy that Yume, #08, has been known to use. It is known as Photonic Energy, the power of light. It is unknown this is a result of Yume merging with Musubi or if Musubi was Yume's twin much like Hikari and Hibiki and always has been able to and only has been brought out with Miya's training and her growing bond with Minato and his other Sekrei.



Executing Kuma-ken.

  • Kuma-ken (熊拳, Bear Fist): A powered punch. One of Musubi's moves and used for the first time during her battle with Katsuragi. Her Kuma-ken has the power to instantly deactivate some opponents like Katsuragi (both manga and anime version do not show the "pattern mode to kill" an Sekirei) and literally blow away the opponent.[2][7]
  • Kuma no Te (Bear Palm): By gathering energy into the palm of her hand, Musubi can condense it. Musubi will then thrust her palm forward at the target, launching a focused blast that will decimate everying in its path.[8]


Further information: Norito

Executing Norito.

Basically, it's a form to use a large amount of power. Every Sekirei it's said to have it. The form to execute requires two steps:

  1. A kiss with their Ashikabi.
  2. A prayer.

It is yet unknown if there are different types of Noritos Sekirei can perform or if each Sekirei has more than one Norito. However, Musubi has shown two prayers while Tsukiumi has shown a longer prayer.

  • Prayer: Fist of my contract! Break the unhappiness of my Ashikabi.
  • English Anime Prayer: By my fist of the contract, my Ashikabi's perils will be shattered!
  • On the prologue of the Manga, it is shown to be a boost or power up over her physical abilities. The first time she uses it when she was searching for a house with Minato. She had the power to jump high into the sky and blow the clouds away with her strength.
  • Prayer: These are the fists of my pledge. Crush the catastrophe before my Ashikabi.
  • Kuma Ryūsei (熊拳, Bear Meteor): Is a strong punch that cause a huge impact on the object that it strikes. She used her Norito in the battle between Minato, Higa, and the Disciplinary Squad. That time, she named her attack and her punch was so strong that it destroyed the junction where they were fighting.

Yume taking over Musubi's body

At times, it is seen that Yume can take control of Musubi's body. When Musubi lost her crest on the bridge while helping Kuno and Shigi escape, Yume awoke due to 'Minato's love for Musubi'. When Yume takes over, a tattoo appears on Musubi's stomach as well as a yin/yang symbol in her eyes. This tattoo may act as a second crest.

Yume's abilities seem to be compatible with Musubi. She is able to use her photonic abilities as well as her super strength as seen when she beat Benitsubasa easily.[9]

It is unknown how, but Yume restored Musubi's crest. If Yume can do this multiple times, it is logical to think that Musubi can never truly be defeated unless she is outright killed.


I've always had it. The beast was always there. Deep down inside me. A big black bear, waiting to be unleashed!

Anime and Manga differences

In the anime, Minaka chose to have the data to save Uzume's Ashikabi on a storage device and have Minato and his Sekirei retrieve it instead of just bringing Chiho to them. During the retrieval, Minaka destroys MBI Tower, which starts the Third Stage.

After MBI Tower was destroyed, Musubi battled Karasuba. Karasuba threated to kill them all if Musubi didn't fight. While she didn't win, Musubi saited enough of Karasuba's bloodlust enough for her to let them go.[10]
