One of the first people Seina and Quille meet upon arrival into town. In love with the idea of love, Heidi currently has a crush on someone and sends love letters to this person often. Energetic, caring, and optimistic- she can come off as charming to some, and annoying to others. Her family owns a small restaurant, and she frequently assists. She also likes to follow fads and give nicknames to people. While Heidi has no affinity for wordeating, she's surprisingly good at inventing spell ideas.
