The Ra Yellow (ラー・イエロー Rā Ierō) is a dorm where the middle ranked students live for their duration at Duel Academy. Students in Ra Yellow either achieved excellent scores in their Duel Academy Entrance Exams, moved up from Slifer Red, or down from Obelisk Blue. The head of the Ra Yellow Dorm is Professor Sartyr. The accommodations in Ra Yellow are much better than Slifer Red's but not as good as Obelisk Blue's.
Their welcoming feast consists of lobster, salad, and juice served in the large dining hall. In episode 12, this dorm is shown to have a cafeteria.
Uniform
The Ra Yellow students wear a yellow jacket that 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 a snap or a button to keep it 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 has a snap or button to keep the jacket closed.
