Aaron was born on Nemesis and, like her sister Manna, she was born into the Black Moon Clan. When the Clan travelled to Earth, Aaron and Manna tagged along with them.
Aaron has a ponytail haircut, with two sides. She wears a purple/red with black designs dress, and in the beggining of the dress there is a purple puff, and Aaron also wears red/black braclelet-like accessories on her arms.
- As with her sister Manna, Aaron's name is a reference to Judaism and the Biblical canon of Old Testament Christianity. Aaron was Moses' older brother.
