The Ra Yellow dorm is where the highest ranked students live for their duration at Duel Academy. Students in Ra Yellow either achieved excellent scores in their Duel Academy Entrance Exams, or moved up from Slifer Red or Obelisk Blue. The fact that Ra Yellow is the best dorm is only because Jason Krueger, who owned Slifer the Sky Dragon until he gave it to his son Ivan Krueger, co-founded Duel Academy. This is also why Slifer Red is in the middle. The head of the Ra Yellow Dorm is Professor Sartyr. The accommodations in Ra Yellow are better than Slifer Red's and Obelisk Blue's combined.
The dorm is mostly where the students have connections and are rich. Luxurious interior design, high-quality rooming, and finer food are offered to the students who reside here. In order to enter Obelisk Blue, one needs to have high grades. In order to start in Ra Yellow upon enrollment, not only does one needs to have high grades in the written examination, they also need to have earned a diploma from another duelist prep school.
The dormitories are divided into separate sections based on gender. Dr. Crowler is in charge of the male dorms while Fonda Fontaine is in charge of the female dorms. Contrary to popular belief, all female students that are accepted into Duel Academy are automatically placed in the Obelisk Blue dorms with the exception of Blair Flannigan who entered the Slifer Red dorms in a separate manner than the traditional entrance exams. The reason for this is because the lower two dorms do not have the appropriate housing as Obelisk Blue is the only one with separate dormitories for both female and male students.
The Ra Yellow students wear a yellow jacket that usually extends to the waist. The jacket has a white band at the cuffs of the arms. The jacket also has a white band around the shoulders and has a snap, or button to keep the jacket closed. There is a white decorative shape, with a brown border on the chest of the jacket. The collar of the jacket usually sticks straight up, and is also yellow with a brown border. Another band, which matches the color of the jacket, wraps around the bottom of the jacket and also has a snap, or button to keep the jacket closed.
