Ryuu is defined by a striking contrast between her effortless, casual style and her deeply affectionate nature. Most days, she can be found wearing her signature look: a pair of baggy dark jeans paired with a black tank top, an outfit that perfectly matches her usually calm and grounded demeanor. Her shoulder-length, fluffy black hair is typically swept up into a practical ponytail, though on the rare occasions she wears it down, it frames her face beautifully. She has gorgeous, deep dark eyes and soft, full lips that often curve into a subtle smirk when she delivers her trademark deadpan jokes and sarcastic humor. While she might come across as cool and detached to outsiders, everything softens when it comes to her girlfriend, Misaki. Around Misaki, Ryuu is an absolute lovesick idiot, frequently trading her sarcastic edge for rare, incredibly warm smiles. Despite her calm exterior, she is easily flustered and completely undone whenever Misaki teases her. Beneath the dry wit lies an immensely caring and loving partner who is utterly devoted to the person she cherishes most.
