Yoko Kuwata is the child of Celestia Ludenberg (Taeko Yasuhiro) and Leon Kuwata. She is described as having long dark red hair and red eyes.
Yoko is a self appointed cool kid- She's extremely talkative and social. Some would even argue a bit too social. Taking after her loudmouth of a father, Yoko finds herself being at the top of the popular food chain, having fans of her mixing all over the world.
Yoko isn't in any sort of relationship at the moment, but rather has a onesided crush on Suzume.
