Here you go guys!
Meet Aria
Aria is a seventeen year old female with long blood red hair and vivid green eyes, just like Lavi. Also like Lavi she is an apprentice of the Bookman Clan, but is not Bookman's apprentice.
She is energetic and keeps to the Bookman Code as much as she can during her time at the Order, even though she slips up quite often and Bookman scolds her for it more than he scolds Lavi
Her weapons of choice are her wings, which are gold and black and are made of Innocence. She also has a pair of daggers that are not made of Innocence but are still effective in a fight
She and Lavi can access each other's Records, they are the only ones in the Bookman Clan that possess this ability
Not much else is known about Aria, being a Bookman her past is clouded.
