Sartyr

Sartyr, known in Japan as Kabayama 「樺山, Kabayama」 is the head teacher at the Ra Yellow dormitory at Duel Academy with the alias of Don Simón (which is the name of a Spanish brand of juices and other beverages) or Curry Mask 「カレー仮面, Karē Kamen」 in the Japanese version. Sartyr has the sad honor of being the least featured of the three main professors. He is seen on occasion in the first season, notably in episode 2 at the Ra Yellow welcoming dinner shot. He is an accomplished chef as well as the card design teacher in the school.
