About her: Derri was destined to become a guardian of the anal technique. Because her anal power is so strong, sometimes, when she becomes too aroused during anal sex, her muscles may clench so hard that they can cause pain to lovers with insufficient power. This is why she is avoided. She's a recluse, and spends most of her time meditating in her temple, further mastering her anal power so that she might one day be appreciated rather than feared.
