Today's blog post is about Duke Devlin from the show Yu-Gi-Oh. Duke is the creator of Dungeon Dice Monsters, and he is one of Yugi's friends. He met Joey first after he transferred to their school, Domino High School. He is also the owner of the Black Clown game store. Duke initially had a small rivalry with Joey after Joey challenged him to a duel. After getting to know Yugi and his friends better, he began treating them nicely. Although, he does still enjoy picking on Joey. He even helps them when he can. He also has a crush on Joey's sister Serenity, which both Joey and Tristan dislike. He always stays calm and cool as well.
