Vanessa (バネッサ) is a succubus and one of the Five Great Heroes representing the Demon Race. After the world is rewritten, she is one of the few who still remembers the old world, and she chooses to cooperate with Kai to restore it. She has a seductive demeanor, but is intelligent, sarcastic, and emotionally mature beneath the teasing surface. Unlike many stereotypical succubi, she does not seduce purely for lust—she understands human hearts and motives and uses it strategically.
