Kasugano Tsubaki

Ability: Claivoyance Diary - Unlike the other Diaries, Tsubaki's diary is a long, green scroll. It predicts her future through her followers' eyes, which gives her great control of her surroundings and any area her followers are in. Her diary can also record near events; the short-term future that will occur after only a few seconds away from the present. However, it can pose as a hindrance in times where a situation changes constantly or when she needs to react quickly.

Tsubaki is the High Priestess and Oracle of the Omekata Religion. Her followers know her as the Sacred Eye because of her supposed powers of clairvoyancy, although this was actually granted to her by her Future Diary. Because she has poor vision, she has had to spend her entire life living in the Omekata temple. Tsubaki is a polite, considerate and friendly girl who fears for her life. She is quite intelligent and relies on her own intuition, believing Yuno will be Yuki's undoing.
