Mozart is Judas' right-hand man and hitman. Whatever Judas wants, Mozart will do so diligently. He has an unfathomable amount of respect for Judas and considers him a reliable friend. His skills as a hitman are what Judas holds preciously, and due to his hard work and dependable actions, even Judas considers Mozart as a valuable friend. Which is rare considering he doesn't have any friends for...obvious reasons. Mozart has one hell of an ego and considers himself a prodigy, similar to Mozart (thus why he gave himself the name). He absolutely loves the classical and baroque style of music and charming the ladies, further fueling his ego about being a prodigy. Regardless of his likes, he's still extremely dangerous and highly wanted for the number of people he's killed, kidnapped, and extorted as well as smuggling things within the city.
Mozart loves to eat cabbage and asparagus. Often times, he would just eat entire bags of asparagus or head of cabbage all day.
Judas' favorite food is chicken wings. He's killed people for taking his wings without permission.
Kire has that accented E because that's how his name is actually pronounced. I'm too lazy to put the "É" at the end of his name which causes confusion for people. I've commonly heard people call him "KAI-YER" when it's actually pronounced "KEY-RÉ". (think of the word ResumÉ. Apply that E/Ayy sound to Kire's name) I know, I know, it's my fault for not correcting it sooner but better late than never I suppose.
Kire has a sweet tooth and eats a lot of sweets, specifically cookies. He tries to hide this all the time but when he gets a tummy ache, it's no doubt from eating so many sweets.
