Chinatsu

She has rather cold eyes and carries the image of a cool beauty but she is also very sensitive and quick to switch between these two aspects of her personality. She is a mysterious person who pops up throughout the Tokiwa village leaving warnings and predictions.

Spoiler

Chinatsu is actually Ojou's fragment of emotions for love and knowledge. Kako made a pact with Chinatsu after Chinatsu arrived in Tokiwa. Both of them can switch personae at any time as Chinatsu's control over Kako is limited.
