Struggling yet brilliant, 19-year-old Minato Sahashi has failed his college entrance exams for the second time, resulting in him being regarded as worthless by those around him. However, the course of his seemingly bleak future is altered dramatically when a beautiful, supernatural woman falls from the sky and into his life. That woman, Musubi, is a "Sekirei," an extraterrestrial with extraordinary abilities. Recognizing the potential of the Ashikabi gene within Minato, Musubi kisses him, initiating a bond between the two of them. This drags him into the high-stakes world of the Sekirei, where he and his new partner must compete against others in a battle for survival called the "Sekirei Plan." However, unbeknownst to the contestants, there is far more at risk that what the competition initially entailed. Manga series by Sakurako Gokurakuin.
