This is a role-swap AU, in which Loona is a Cherub, and Collin is a hellborn.
Even tho this is a rolse-swap, both of them have their original personalities, so, even tho Loona is a Cheerub, she's still a tad bitchy and has some anger problems (besides the gothic outfits), and Collin is still a sweet lil' bean.
In this Au, Collin was adopted by Blitzo instead of Loona (duh), and now works for I.M.P.
This is a recreation of the adoption photo of Loona and Blitzo!
