Yvette Dillians is a normal student at Hope's Peak High and one of Chi's classmates. She is known to be cheerful, non-judgmental, goofy, comedic, and a heart of gold. Yvette Shares two classes with Chi: Entomology and Computer Coding. When she saw Chi, she knew something was off about him, but not in a bad way. Rather, because she sees Chi function differently than others around him. The two eventually began having conversations with each other, and Yvette now understands who Chi is: Flame, an autistic man who can switch between forms. The two eventually grew a bond with each other that can never be broken, marking Yvette as one of Chi's supportive allies.
