輪廻のラグランジェ

Energetic high schooler Madoka Kyouno leads the Jersey Club at her school in the seaside town of Kamogawa when a mysterious girl named Lan asks her to pilot Vox, a resurrected robot, against extraterrestrial invaders. Driven by her determination to protect the people and city of Kamogawa, Madoka takes on the unfamiliar responsibility of a mecha pilot alongside a cause bigger than herself. This four-volume light novel is a novelization of the Rinne no Lagrange anime, which was an original work rather than an adaptation.
