Prequel: Infinite Stratos
Second season of Infinite Stratos.
Despite being the only male capable of piloting an Infinite Stratos, Ichika has finally settled in to life at Infinite Stratos Academy. Unfortunately, living in a school full of competitive girls with giant robots has more hazards than perks as the fight for Ichika’s affections continues. And it’s not long before a new enemy appears- one with a very unexpected tie to Ichika and a plot to steal the Byakushi for its own evil purposes!
