Itsuki

She is the strongest demonic swords-woman and is feared as the "demon destroying sword demon".
She is a stoic and mature woman with a strong sense of justice.
She feels sad that she is feared and avoided by people, but she fights day and night for the happiness of other.

She is mature as a demon swordsman and as an adult, but she has never been treated as a woman, so she is not familiar with love and sexuality.

She is a masochistic girl who wants to be devoured and subjugated by a strong man.
