Rinne no Lagrange

Synopsis

While enjoying the fresh morning air at the beach on the way to school, Madoka Kyouno spots a drowning girl in the distance. Madoka manages to rescue the girl, but ends up misplacing her school uniform. As a solo member of the Jersey Club, Madoka participates in various club activities after school, including tennis and kendo. While Madoka walks home, a strange girl returns her school uniform. Later that night, Madoka is questioned by her cousin, Youko Nakaizumi, as to whether or not she likes Kamogawa. The next day, Madoka once again meets the strange girl, who introduces herself as Fin E Ld Si Laffinty, nicknamed Lan, asking Madoka to pilot a robotic aircraft known as an Ovid at an offshore base called Pharos. As Madoka touches the Ovid and experiences an unusual flashback, rebel organization Kiss member named Array, piloting the Ovid Teneritas, appears from outer space and attacks Pharos. Lan reveals herself to be an alien sent to protect Madoka and her Ovid, the two of which are linked together. Madoka agrees to pilot her Ovid, which responds to her emotions and changes into a robotic form to fight against Array, defeating him using Madoka's knowledge of wrestling.
