Description: Sonomi is the mother of Daidouji Tomoyo. She is the head of a powerful company and very wealthy (thus, all the bodyguards). She is cousins with Kinomoto Nadeshiko and Sonomi loved her very much. She was as angry as the Amamiyas when Kinomoto Fujitaka married Nadeshiko and doesn't try to hide it when she sees him, rather, she blames him for Nadeshiko's death. She adores Kinomoto Sakura, however, and let's Tomoyo wear her hair long, which reminds Sonomi of her cousin, because Nadeshiko had long hair.
