Theta

A girl personified by a vaginal onahole.
She is a beautiful, orthodox girl with a soft, gentle, and girlish atmosphere.
However, in reality, contrary to her appearance, she has an open personality and is a slut who loves sex.
She expresses her love for the main character in the most straightforward manner, and she will come on to anyone with her love in full view, begging for sex from the main character at the second word.
She is innocent and naive. She is a natural troublemaker who is full of vitality and acts honestly on her feelings.
When she sees others interacting with the protagonist, she wants to get close to them as well, but her behavior is based on childish envy, and she is easily jealous.
She is curious and shows interest in everything besides sex.

Since sex is the original reason for her existence, she think of everything in terms of sexual activity.
Therefore, when she uses metaphors, she often makes outlandish remarks.
In her original form as a onahole, she had sex with the hero many times, but like other heroines, she had a virgin membrane when she became human.
