Infinite Stratos (Seasons 1–2)

Infinite Stratos (2011) is an anime series you can watch online on iFILM. In the near future, humanity builds a combat exoskeleton called the IS — mind-controlled, faster than any jet, almost impossible to stop. There's one catch that rewrites global power: only women can pilot it.

With the weapon useless in actual war, it gets funneled into competitive sport, and future pilots train at the elite IS Academy — an all-girls school drawing talent from every nation. Then ordinary teenager Ichika Orimura turns out to be able to activate an IS too. He's enrolled as the only boy among hundreds of rivals: gifted pilots, childhood acquaintances and proud beauties, each with her own designs on him. From there it's mecha duels, jealousy and full-blown harem chaos.

This is a mecha shounen with a heavy comedy streak, swinging between flashy robot fights and lightweight romantic mayhem around its lone male lead. It lands for viewers who enjoy hardware, fan service and breezy "one guy, a crowd of admirers" setups. Stream Infinite Stratos online on iFILM.
