Jeanne is Bayonetta's rival in video game, Bayonetta.
500 years ago, Jeanne is an heir to the Umbra Clan. She picks Bayonetta for her fight, but she's defeated, trigerring a war between the Lumen Sages and the Umbra Witches. Fearing that the Left Eye jewel fall into the Lumen's hands, Jeanne seals Bayonetta into a lake.
In the present day, she is allied with Balder and the Lumen Sages. She fights Bayonetta four times.
Jeanne is defeated for the last time, and it is revealed that she and Bayonetta are never enemies, but friends all along. She is presumed killed by an explosion of two rockets.
It is revealed later on that she's not dead, and that she used the jewel to protect herself from the explosion. When Bayonetta is captured by Father Balder, Jeanne comes to rescue as he is revealed to have brainwashed her into allying with him. She's presumed dead again by the shockwave from a statue, but returns in the end to help Bayonetta defeat Jubileus, The Creator.
With Bayonetta dead, Jeanne is disguised as a nun and prays to summon Laguna. When the Laguna comes for her, Bayonetta rises from her coffin and fights with Jeanne against them.
