Musubi (?, Sekirei #88) is the main heroine of the series. She met Minato when she literally fell out of the sky onto him while being chased by Hikari and Hibiki. Musubi specializes in hand-to-hand combat which utilizes her greatly enhanced strength, enforced by the heavy combat gloves she always wears. Musubi's outfit consists of a short red skirt and upper clothing resembling the robe traditionally worn by mikos (possibly passed on to her from Yume). She is quite naive, often saying things she doesn't understand and is the most "childish" of Minato's Sekirei (even more so than Kusano), yet at times can be insightful. Musubi is the most "competitive" of Minato's Sekirei, often showing great eagerness to fight other Sekirei, but never fails to be polite, usually introducing herself and then asking for permission first before fighting them. Two running gags in the story are how her clothing always ends up in tatters, revealing her sexy curves after every fight, and how she seems unable to land on her feet after leaping from a great height but always crash-lands on top of Minato. After hearing Tsukiumi say that she is Minato's wife, she decides that she is his wife too.Ch. 24 She eats a lot and is a fairly decent cook (but only curry in large amounts). Because Musubi eats so much food to maintain her energy level, Miya's nickname for Musubi is "Airheaded Glutton".Ch. 54 During moments of extreme emotion (such as anger or jealousy), the image of a ferocious black bear appears behind her, causing some (mostly Benitsubasa) to refer to her as "The Bear". Musubi's known attacks are the Bear Fist (??, Kuma-ken) Ch. 66 and Bear Meteor (??, Kuma Ry?sei) Ch. 87 and her Norito is "By the fists of my contract, shatter the perils of my Ashikabi!" After all the Ashikabi collapse on Kamikura Island, Musubi is chosen from among Minato's Sekirei to represent them in the final fight on Kouten against Miya in order to save all the Sekirei and their Ashikabi. After accomplishing this, she stays to becoming the new power of Kouten in order to restore all of the fallen Sekirei, but her "bear" side still emerges at moments of extreme jealousy whenever any of Minato's adult Sekirei get too close. She returns to Minato's side a year later.
