Jeanne d'Arc

A twelve-year-old young girl from Domremy with a kind and gentle personality. After having been mortally wounded by the English when Domremy was attacked, Montmorency put half of his Philosopher's Stone into 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 Ulysses for only three minutes; in this form, she turns into a powerful and almost invincible fighter. At the same time, Jeanne becomes extremely brutal and sadistic due to the stone amplifying her arrogance.
