Decium 

Rarest. He’s very proud of his name because it sounds like a chemical element, he would love you to call him DEC or D if you are close. He struggled with the toughest problems from his origin but eventually overcome them! He is tsundere and athletic, when he focus in sports he blazed as the sun because of his dazzling skills and strong stamina. He is goofy and kinda cocky in person because of the trauma from his past cause him insecure. Sometimes he can be a troublemaker, but everyone would love to cover his ass once his bright grin is showing.

“Oh Decium! I can’t think of anyone else who can be even more outrageous than you!”
