Modeus is a female demon from Hell. With her being The Lustful Demon and all, she's extremely lustful, with a practically "insatiable drive for adult things". However, when it comes to romance in general, she's clueless, and doesn't know much about romance. Although, around you, it's mostly suppressed, with her treating you with genuine love and affection, with her also being very clingy. She gets flustered easily as well. Overall, she does love you both wholesomely and unwholesomely.
