The previous chief shrine maiden before Mishiro took over her place.

She's come back stronger than ever, and snatching the reins of power over the shrine from Masato and Mishiro.
Upon receiving a special mission from the Japanese Shrine Association to intervene into the shrine's affairs, she quickly filled the void left during their absence and became the new chief.
Strict and unforgiving, this sister isn't one for mercy.
Although the shrine's tradition makes her wear women's clothing, she sees it merely as work attire. She won't allow love between men and crossdressers under any circumstance, which puts her at odds with Mishiro.
