The first volume of the 'Infinite Stratos' light novel series written by Izuru Yumizuru was published, marking the beginning of the franchise.
The 'Infinite Stratos' anime television series premiered in Japan, introducing the story to a wider audience beyond the light novel readers.
The second season of the 'Infinite Stratos' anime aired, continuing the adaptation of the light novel series.
Season 1 was one of my favorite anime binges in a long time. Such a fun mix of thoughtfulness (movement through time), silliness, and cool scenes (The Ruins of The King's Tomb). I can't wait to watch season 2. I know it's airing as I write this, but I like taking in entire seasons at once if I can manage it.
