Aquarion Evol (2012)

After accidentally forming the legendary mecha "Aquarion", Amata finds himself at a pilot-training academy. It's all awkward dates, hijinks, and threesomes until otherworldly beings start abducting powerful female students. As a mysterious megalomaniac plots interplanetary disaster, the fate of the galaxy depends on whether or not the hormone-fueled academy coeds can come together to fight evil.
