Rangiku is an attractive woman with long, wavy, strawberry-blonde hair (worn short in her youth), icy blue eyes, and a beauty spot to the right of her mouth. Her most distinctive features are her very large breasts, which are even larger than Orihime Inoue's. She also shares Orihime's strange taste in food. She dresses in the garb typical of shinigami, though her robes hang loose enough for her ample bosom to be revealed. She wears a necklace and a pink scarf over her shoulders. In addition, her lieutenant's armband is worn on her uniform's sash, as opposed to around the arm.
Rangiku tends to be a slacker who doesn't like paperwork and loves to drink sake. She's not the least bit modest about her appearance, frequently referring or complaining about her large breasts in casual conversation. She even tries to bribe Ichigo Kurosaki into letting her stay at his house using them, though unsuccessfully. Her easy-going and free-spirited personality is in sharp contrast with the serious Hitsugaya, but the two seem to be quite close, regardless. Rangiku is almost constantly by his side and has shown her loyalty to him on several occasions. While she seems somewhat self-centered, she is sensitive to the feelings of others, evident when she sees the concern Hitsugaya has for Momo Hinamori, the guilt Izuru Kira shares with her when Gin Ichimaru is revealed as a traitor, and when Orihime feels depressed about her role in Ichigo Kurosaki's life. Despite her lackadaisical image, she can be extremely serious when needed. She's shown to be somewhat maternal, especially with Orihime and Momo.
