Height: 175 cm (5'9") A snake familiar at the Yonomori shrine. Nanami saved his life from her cruel classmates by releasing him out a window, he fell in love with her, so he left an engagement mark on her wrist. After a day, he arrives at her school and whisks her away to the shrine, which she is unable to escape from. Unlike other snakes, he was apparently raised in a greenhouse and has little knowledge of how most snakes behave. Mizuki is also very lonely because his god has vanished; she once existed when people visited the shrine and believed in her, but now no one lives in the valley and she has dwindled away to nothing. However, he still believes that she exists and will return. As a result, he wants Nanami to live with him forever at his shrine, but when she refuses he tries to rape her and is interrupted by Tomoe. It is revealed that the shrine is an illusion meant to hide his god's favorite plum tree, which Mizuki treasured. Nanami promised to come look at the blossoms with him whenever he felt lonely. Like Kurama he seems to still be harboring a crush on Nanami, and even comes to cook for her when she's ill. In chapter 23 Mizuki decided to become Nanami familiar making a contract by kissing her while she slept. (Source: Wikipedia)
One of the girls in the Manga Society at the time Ogiue attempted to join, she seems to harbor strong feelings of resentment towards Ogiue. Criticizing Ogiue for slipping into her Tohoku dialect when she doesn't speak formally, Yabusaki herself speaks in a highly pronounced Kansai dialect, which she says scares those from Kant�. When Ogiue is rejected as a vendor for the next ComiFes, Yabusaki (grudgingly) invites her to become a guest artist in her own circle's d�jinshi. Though she appears only towards the end of the manga, she shows up much earlier in the anime, in episode 3 of season 2. (Source: Wikipedia)
