Sekirei

Minato Sahashi, a typical ronin student, finds his life suddenly changed after meeting a strange girl named Musubi. Minato discovers learns that she is a 'Sekirei' and that he is her 'Ashikabi' (ie. Master).

When Minato's landlord evicts him from his apartment, he and Musubi must search for a new place to live. Through a twist of fate, the two encounter a young woman named Miya Asami, who runs a boarding house (Izumo Inn) and are allowed to stay.

Minato takes a job at a local construction site where he meets another Ashikabi, Seo Kaoru. With Seo's help, Minato infiltrates a nearby botanical garden, drawn by visions of a young Sekirei girl named Kusano, after Seo and his Sekireis eliminate a MBI roadblock in front of the garden. Musubi soon arrives and with her help, Minato rescues Kusano, who later makes Minato her Ashikabi.

Minato, Musubi and Kusano are startled by strange events at Izumo Inn. Unknown to him, Minato is being secretly watched by a mysterious girl. When Musubi leaves to gather groceries, she is attacked by a satellite weapon controlled by the mysterious girl who then surprises Minato in the washroom.

The mysterious girl turns out to be Matsu, a Sekirei who has been hiding at the Inn. Matsu becomes Minato's third Sekirei. Minato has dreams of another Sekirei, later identified as Tsukiumi, a Sekirei that despises Ashikabi. Minato and Kusano go looking for her and encounter Seo. Hikari and Hibiki soon arrive chased by Tsukiumi.

Tsukiumi attacks Minato to prove that she doesn't need an Ashikabi, but she cannot release her full power. Hibiki and Hikari show her the power of fully winged Sekirei, but Minato shields her from the attack. Finally understanding Minato's feelings, Tsukiumi becomes his newest Sekirei, leading to a comical homecoming.

Things calm down at the Izumo Inn (for the most part) as tensions rise for the MBI, and Sekirei and Ashikabi from all over Tokyo try to escape. Something big is surely set to happen. Meanwhile, Benitsubasa plots her revenge on Musubi.

Tensions in the city continue to escalate. Minato and Tsukiumi go to visit his sister Yukari when they are attacked by Haihane, who draws Tsukiumi away. Left alone, Benitsubasa captures Minato in an attempt to draw Musubi out and into a fight. While Matsu and the others try to determine Minato's location, Kazehana manages to track him to a warehouse, but must face both Benitsubasa and Haihane in order to free Minato.

Kazehana begins fighting a losing battle, but when Minato protects her from certain danger, she kisses him to acquire her wings, then easily defeats the Disciplinary Squad duo. Musubi and Tsukiumi arrive and take Minato to the hospital. There, he learns his mother, Takami, is part of the MBI, and Karasuba makes a great proposition to Musubi.

Uzume starts to feel the weight of eliminating other Sekireis to make sure her Ashikabi is safe. Kagari starts reacting more to Minato, furthering his disgust of having a male Ashikabi. In a moment of weakness, he faints in Minatos arms and almost gets winged by trying to kiss Minato before he comes to his senses. Minaka sends out another message to all Ashikabi that one last Sekirei remains in the north, meaning Kagari.

Minato tells Kagari that Minaka sent out a message to inform all Ashikabi the last Sekirei lives in the North and to hurry to wing it. This prompts Kagari to head out and try to kill Minaka, but runs into other Sekirei wishing to capture him for their Ashikabi. While Uzume and Akitsu fight for his possession, Minato and his Sekirei set off to defend him and wing him before the other approaching Sekireis and their Ashikabi arrive.

Akitsu continues to fend off Uzume while Kagari begins to lose control of his powers. Then, when Mikogami orders Mutsu to interfere in the fight between Akitsu and Uzume and capture Kagari, Izumi Higa's secretary, Kakizaki appears. Mutsu, realizing it would be useless to fight against Kakizaki and the other Sekireis he brought with him, retreats along with Mikogami and Akitsu. Before she leaves, Akitsu explains to Kagari why she has a master and tells him that she envies him because he can still be winged.
