Uchuu Kaizoku Mito no Daibouken

Aoi Mitsukuni expects his mother's return from a business trip to bring a familiar reunion. Instead, he learns that her human appearance is a disguise and that she is Mito, a notorious alien pirate.

Her enemies and pursuers bring the dangers of space to his doorstep. Aoi must come to terms with a mother whose life he barely understands, while Mito tries to balance her fearsome reputation with the much more personal business of being his parent.
