Kyoko Sasagawa is a Namimori Middle School student whom Tsunayoshi Sawada admires and has a crush on. She is the younger sister of the Vongola Sun Guardian, Ryohei Sasagawa.

Character outline[]


Kyoko is a young teenage girl, with a slender and short build. Despite being the younger sister of Ryohei she doesn't seem have any traits in physical appearance, and she is described as a rather cute girl, especially by Tsuna. She has short golden brown hair (which is colored blonde in the manga on certain occasions), with bright golden eyes. Sometime during the Curse of the Rainbow Arc, Kyoko's hair was now shorter, without any given reason.

While consistently changing outfits in the series, her most prominent outfit is her Namimori Middle School uniform. She wears a white formal shirt, a dark sweater vest with a red bowtie, a gray skirt, black knee-high socks and brown shoes.

Her future counterpart has much longer hair that reaches down to her back, she wears a dark green hooded jacket and a light green dress underneath.


While far from stupid, Kyoko is a somewhat air-headed girl that lives a mostly carefree life in Namimori, she doesn't seem to question many of the odd occurrences in her life, such as the idea of an infant being a hitman in the mafia, or being sent ten years into the future, which she often assumes are school activities or harmless jokes, to the point where she even believes in what her older brother tells her when he receives an injury, even if they sound too ridiculous to be true.

She is a kind and caring girl, always looking out for her older brother and her friends. Kyoko is rarely ever shown to get angry at other characters, with some of the rare occasions being towards Kensuke Mochida, who claimed that she was a "prize" during Tsuna's kendo match against him, and when Tsuna and his guardians refused to explain the mafia and Millefiore Famiglia to Kyoko who had no idea why she was trapped in the future, in which she temporarily went on strike and refused to cook and clean until she was given an explanation. Kyoko has a fondness for sweets, taking the third Sunday of every month and having an appreciation day where she eats as many cakes as she wants.
