Yuuka

Yuuka is the Spirit Witch of Torres and a slave, not only because of Torres's law about women slavery, but also because of her statut : She's a "Corrupted Witch", which mean she cannot be broken by monsters, but the more she use her power, the more she become lewd. Corrupted Witches chose slavery because of the pleasure they have with sex and using powers.

In Torres, She know as the "Magical Hair Slave" since her magic is about Hair control.

Yuuka protected Torres from monsters attack until Lilina, in Sofia's body, came to help. Yuuka thought that the Spirit Witch were too weak to help, but Owen and Youde convince them to accept her help. Together, they defeat monsters, but Yuuka were injured in the fight. Unable to fix her soul, Lilina had to turn into an Undead Witch to save her. Yuuka show more respect to her after this. Later, her and Lilina noticed that a fragment of her spirit was absorbed during the rescue process. This situation give to Lilina the power to comunicate with Yuuka via the Spirit Witch Zone and even use the Magical Hair form. Yuuka told that Spirit Witches usually have only one form. This rule remain unbroken until someone discover the Undead Witch form.
