Evermilion

She is a white demon who resides in Honoka’s body, she is the so called “white stuff” that the tower witches were after. She laid dormant for quite sometime, until Honoka- during his encounter with Medusa, swallows the medicine given to him by Chronoire that allow her to manifest in a physical form and eventually save him from being harmed by the latter . She is basically independent minded entity who somehow dislike the idea that she resides inside Honoka’s body and that the tower witches are interested in her powers.
