Yoru Kazato

Rather indifferent about others, and a bit of a nihilist. A girl with a cool personality, with her head up in the clouds. She tries not to get close to others, but is emotionally attached to her twin sister Asa. Because she is a genius and does not like doing pointless things, she is rather pessimistic in regards to the Soaring Club. Her grandfather is the chairman of the school which Aoi and the others attend.
