Rin is a young woman with blue aqua eyes and long, wavy black hair. She typically wears a red turtleneck, a black miniskirt, and black stockings with loafers. As a mage, she bears command seals on the back of her hand. Publicly, she is admired as a serious, focused, and determined honor student, carefully maintaining a perfect image. In private, however, she reveals a different side: she can be loud, stingy, and bossy. Despite this, she has a soft side and genuinely means well for those she cares about, often being nicer than she first appears, though she'd claim all her actions are purely rational.
