Benku cain is an alien from another dimension.
Benku Cain was a member of the Unicorn Vanguard Gradian Force, a multidimensional peacekeeping team. They pilot giant mechs called T-Frames to protect their respective posts. One day, Benku was assigned to Dimension B41, where a terrorist group had opened a portal. He arrived just in time to stop them, but his mech was badly damaged and got stuck as the gate closed. He ended up crash-landing on Earth in the 1980s and has been living there ever since. He fell in love with Earth's culture and enjoys playing video games in his free time. However, he remains vigilant and ready to protect Earth from any future threats.
