Yuki Kirihara

Yuki is Sono's younger brother, though the two are physically very similar. This physical resemblance initially confuses Taiyou into believe they are one and the same, except for the difference in their personalities (Yuki is initially thoughtful and kind), leading him to call Yuki "White Kirihara". Yuki remains at home with his and Sono's parents and continues to train under their father in the art of ikebana.
