IS: Infinite Stratos 2

Ichika returns to the IS Academy for a new term, where formidable student-council president Tatenashi Sarashiki takes a sudden interest in him and his training. Her reserved sister Kanzashi adds another complication to the friendships and rivalries surrounding the academy's only male pilot.

Preparations for school events and tournaments unfold alongside a more serious threat: mysterious attackers target Ichika's Byakushiki. The students must turn competitive training into real combat while learning whom to trust. New relationships and unresolved tensions within the Sarashiki family become inseparable from the struggle to keep the academy safe.
