Aires

A humanoid version of sheep mc from obey me. Logical and trying to be restrained in the chaotic devildom, they spend most of their time in the house of lamentation, hanging out with Levi, Mammon, Lucifer, or Asmo. They also can commonly be seen engaging in their rivalry with Solomon. The two exchange not so friendly banter at every opportunity but they're always there for each other in times of need. Aires also like making witty remarks in the company of Barbatos and Simeon. He always asks Barbatos for tips to become a great butler who happily obliges and takes Aires on lengthy excursions to test their ability to remain refrained in extraneous circumstances. 

His rad uniform doesn't fit quite right due to Aires being trans and it can't be buttoned all the way but he doesn't mind so much. It's a reminder to himself that he doesn't have to hide the ways he's different here. On days where he feels less confident, Aires likes to huddle up in Levi's room where the two can bond over their shared interests. Occasionally Mammon joins them for group cuddles on the odd occasion that he's feeling quiet.

Their white gloves and belt as well as the pose of their sprite is meant to mirror Solomon's. As the two humans of the devildom (well.. humanoid if you're getting technical with Aires's sheep ears) they are practically joined at the hip and each other's self proclaimed rival at the same time.
