Occupation Maiden Alternate Height 157 cm Tsubaki Kasugano is a maiden and figurehead of the Omekata religion. Her "Thousand League Eyes" diary is unlike the other diaries, as it is a scroll, rather than a cell phone. As its name would suggest, it is able to report the future of all her followers. Unlike Yukiteru's diary, it is not limited to just her surroundings, but also sees far events, such as seeing the events Yuki had accomplished a great distance away from where she resides. Her diary can also record near events; the short-term future that will occur after only a few seconds away from the present. This provides Tsubaki with massive amounts of information to work with. However, it can pose as a hindrance in times where a situation changes constantly or when she needs to react quickly.

Spoiler

She was born with bad eyesight, only able to see a few feet in front of her. Her parents capitalized on this by setting her up as an "oracle" and creating a cult around her. After her parents died in a car crash, however, she became a plaything for the Omekata and was even raped by it's members. As a result of her experiences, she has become jaded with the world beyond her vision, and wishes for it to disappear. Tsubaki wants Yukiteru's abilities in order to avoid the prediction her diary made about herself. As she is able to control her worshippers, Tsubaki does not make use of any weaponry.

Spoiler

When Yuki and Yuno travel in time to the next world their actions shape a future in which Tsubaki's parents never take their fatal car ride. This prevents the cult's transformation into an evil cult, and Tsubaki is spared from her horrible fate.

She is named after Proserpine(Furrin) — roman goddess of Underworld.　The characters of her name mean "Spiring" (春), "Day" (日), "Field" (野), and "Camellia"(椿), respectively.
