Second season of Infinite Stratos.

An extended version of the second season's first episode, which is under the same title.

Having died in a car accident, Tsubasa Kurata—an otaku from modern Japan—is reborn in the Fremmevilla Kingdom, a medieval world where powerful mechs called Silhouette Knights are used to fight horrific demonic beasts. Born into a noble family under the name of Ernesti Echevarria and bestowed with prodigious magical abilities, he enrolls into Royal Laihaila Academy. This school of magic trains young men and women on how to pilot the Silhouette Knights, prepping them to protect the kingdom from threats, both demonic and human. Ernesti teams up with the twins named Adeltrud and Archid Olter with the goal to create his own Silhouette Knight one day, a feat unheard of for several centuries.

Half retelling of the original Frontier series, half new story. Conspiracies arise within the Frontier government when Sheryl Nome arrives to the colonial fleet for her concert and is soon marked as a spy for Galaxy while childhood friends, Alto Saotome and Ranka Lee both try to achieve their dreams as the battle between Frontier and the Vajra draws closer. This movie serves as part one of the Frontier retelling and will conclude with the second, The Wings of Goodbye.
