Koishi is a mind-reading satori, and the little sister of Satori Komeiji, now inheriting the Palace of Earth Spirits and ruling hell after Satori’s passing. For a while, she closed her third eye, essentially making her lose the ability to think. Now, as hell’s queen, all her bad past memories and guilt have come back to her following her eye’s reopening. She has short green hair, fair skin, and green eyes. Her former bubbly personality is completely missing.
