Story is totally incomplete, kind of haze. Art style is good no complaints. Character looking good too. I miss some realistic emotions, Ichika kind a like a idiot. There is more better series can you find, some adult situations is enjoyable, but no relationship growth between them. Infinite Stratos season 2 and special episode kind of incomplete story. Like need more season to complete it. Season 2 story nice, but fighting with another sister, suddenly Tabane join with enemies, helping orimura another sister, and most important thing "Sarashiki, Tatenashi" suddenly disappear, how? Is she 'Ichika's 'IS' katana sword spirit? Some information are not reviled.
