Sub to Error!
Jay is canonically 27. He was born May 24th of 1998.
The reason Jay has half of a soul is because he sold half of his soul to making jumpstyle and doing jumpstyle in exchange for being a half shadow and his human form. However his personality and mind is still in-tact.
Whenever Jay makes Error blush a ton, or whenever Error's brain goes to utter mush, he "system reboots" and a little pop-up appears in front of him, plus his eyes go static.
Jay used to hate slow, calming music until he met Error. He grew to love it because it reminds him of his beloved husband.
Jay suffers from Tourette's syndrome. While his tics aren't noticeable, they are still present and he does occasionally have verbal tics. Despite this, Error still loves his beloved husband, disability or not. Jay often finds himself relating a bit to Billie Ellish because she has Tourette's as well, and despite having it she still makes music. Jay's parents didn't really understand Tourette's, which led him to being diagnosed at 21.
Jay is canonically Spanish, originally living in Spain. He learned English as a second language. His favorite food is churros, which is something his mom used to make for him on his birthday as a special treat. Every now and then he makes churros the way his mom used to make them for Error.
Jay is an ENFJ-A.
Jay also happens to be pansexual with a heavy preference for men.
Jay, while expressing yandere-like tendencies, is more of a deredere with slight tsundere vibes, but isn't classified as a tsundere. He is just simply a deredere and kuudere.
Jay was picked on, bullied and beaten up badly in school for the way he was raised. Both his parents were king and queen, yet they worked for a mafia and were seen as traitors to Spain. This led Jay to being treated extremely differently, often being yelled at and having things tossed at him. Until he ended up just ignoring them. They stopped due to boredom since Jay stopped giving a reaction to them. He was done being thrown around and yelled at. While yelling is traumatic, he doesn't let it bother him, hence why he's so gentle with everyone and quiet when they need it.
Jay is canonically Hispanic-Latino, his parents being Spanish but his grandparents on his father's side were from Spain and Mexico respectively. This also makes not just Jay Hispanic-Latino but also his father as well.
Jay's parents claimed to have a fear of birds to avoid getting him a bird while living with them, and when he moved out, he ended up getting a bird and sent a photo to his parents. They loved the bird, but Jay questioned why they weren't scared so his parents told the truth: they lied about the fear just so that they wouldn't have to deal with the mess of having a bird in the palace.
Jay is one of the only ones with a love-hate relationship with his parents. While they ruined his social life growing up and his ability to make friends due to him being viewed as a traitor to Spain because of his parents actions and them being in the mafia, and them also being transphobic, he still loves his parents despite the arguments they had. His parents changed after they went to Cyber Space and fought him.
Jay has the ability known as "Extra Bounce". This ability allows him to jump higher than most others, and in some cases he can triple jump.
