Gaia Getter A-kun

ガイアゲッター アークン

Far away from our solar system there is a 3rd planet of another called Mangana. A Queen rules it with an iron fist. The first Prince, A-kun, is nothing but naughty kid and so the Queen gives him the task of invading Earth to prove his worth. A-kun comes in tow with his semi-forced attendants and hijinks ensue.
