Satsuki Miyanoshita 宮ノ下さつき

Satsuki is the main character of the show. She moves with her father and her young brother Keichirou to the hometown of her deceased mother, where she finds that her mother confronted several evil entities that haunted the town, which included Amanojaku, and wrote all her supernatural experiences in a diary, which is entitled "The Ghost Journal."

Satsuki is very strong, brave, and determined, but sometimes bit moody, mostly because of Hajime trying to see her underpants. In the Spanish Dub, she was named "Claire". Her nickname in the Animax dub is Suki.
