Jun Kiwatari is a minor antagonist in Kakegurui.
Jun is very tall and muscled man. He has short, dark brown hair with sideboards, tan skin and black colored eyes. He wears the Hyakkaou Private Academy issue uniform that consists of a red blazer with black trim that lines the cuffs and collar and has gold buttons for decoration. He wears a white button up shirt underneath with the top unbuttoned as well as a pair of gray-black colored school jeans with and brown loafers.
Jun is portrayed as a typical bully type. He is agressive, arogant and sadistic person, who loves dominate others. For example, he made use of Tsubomi Nanami's housepet status and cut her long hair, probably only because she really valued them and threatened Yumeko Jabami when she didn't strip in front of him and his friends.
