Jeanne d'Arc (ジャンヌ・ダルク Jannu Daruku?) was one of the main characters of the Ulysses: Jeanne d'Arc to Renkin no Kishi light novel and the titular protagonist of the anime series. She was a twelve-year-old young girl from Domremy. After having been mortally wounded by the English when Domremy is attacked, Montmorency has put half of his Philosopher's Stone in her body to save her life, making her the new Ulysses. Due to her young age and having only half of the stone in her body, Jeanne can become an Ulysses just for three minutes; in this form, she turns into a powerful and almost invincible fighter, but at the same time she becomes extremely brutal and sadistic, since the stone's power implements her arrogance.
