Ail

Ail was an alien who came to Earth with An on the Makaiju. While living on Earth, he adopted the name of Seijuurou Ginga(銀河星十郎). To help An steal energy from humans, Ail would summon a Cardian by playing a melody on his flute. During his appearance in Sailor Moon R, he developed a crush on Usagi Tsukino. He also considered himself a rival of Mamoru Chiba, whom An expressed romantic interest in.
