Hoder is one of the 7 Upper Classmen who are studying for their Mark of Mastery exams in Scala ad Caelum to become fully fledged Keyblade Masters. She is the older, protective sister of her younger brother, Baldr, who is also studying in Scala ad Caelum - just as a Lower Classman. She believes in the light, and is full of it. She studies with fellow Upper Classmen, Vidar, Vala, Vali, Heimdall, Helgi and Sigrun, who are all taught by Master Odin.
