Iron Widow has a similar premise to Pacific Rim, namely that humanity is fighting an alien threat using giant robots with two bonded pilots. However, Iron Widow is more fantastical, with the robots requiring male and female pilots, and the female pilot often dies as a result of their lifeforce being used up by the male pilot during battle. The protagonist, 18-year-old Zetian, sets out to find the ace male pilot who killed her sister in such a manner and take revenge.
