Rangiku's favorite food is dried persimmon, just like that of Ichimaru. She also shares Orihime's very strange taste in food. She dislikes bamboo shoots because she finds their taste too strong and their texture unpleasant. Her first name, Rangiku, can be translated to "rangaku" which in japanese terms, means western medicine.
Not much is known or mentioned about Rangiku's past. She came from Rukongai and was rescued as a child by Gin Ichimaru the two soon became friends. She was once asked by Ichimaru during her childhood when her birthday was. Rangiku also had been alone for as far as she could remember.
Rangiku may strike many males as one of the better looking females of Soul Society’s top echelons, even if the major reason is her cleavage. Hitsugaya, determined to get to the bottom of the matter, realizes that the only way to do so would be to stop the execution. He thus orders Rangiku to follow him to Central 46 Chambers, where they make the shocking discovery later that the entire Central 46 Chambers has been massacred. When Hitsugaya leaves, Izuru releases his own ZanpakutÅ to fight against Rangiku who had been ordered to continue the chase.
