Tao Jeanne

Iron Maiden Jeanne is a fictional character from the anime series Shaman King. She is voiced by Yui Horie in the Japanese version. She was born on March 2, 1990 and her blood type is AB. An 11-year-old young girl from Mont Saint-Michel.France and powerful shaman in her own right, Jeanne is the leader of the X-Laws.

Appearance
She is known for her red eyes and very pale hair and almost fragile appearance. She is extremely charismatic; in the English anime, Tamao Tamamura calls her a "princess" after hearing her speak for the first time. When she is in the maiden except in her PJs. When in her armored form, Jeanne wears sandals with spikes going into her feet (yet they do not pierce her) and also wears a giant lock on her abdominal region, like a chastity belt. These two items seem to represent self-flagellation. Though she is seen as emotionless, the eyes on the face of the Iron Maiden will cry tears of blood when she herself feels sad and needs to cry. During the mission to bring back len she wore a very neat dress and dress shoes. this outfit became her street clothes later on.

Personality
Jeanne's passionate hatred of Hao derives from the fact she believes him to be the ultimate evil. While she believes herself to be a martyr of sorts and is still very soft-spoken and compassionate towards the X-Laws, specially towards young Lyserg Diethel (she defended and praised Lyserg several times when Marco was too hard on him), she has become detached from humanity and is unable to see that not everything is black and white.

In a way, Jeanne is like Hao, since she kills whoever stands in her way indiscriminately, if they don't surrender to her pleas for peace. They both believe that they are helping the world and their actions will be justified by the end results. The difference is that Jeanne honestly believes she is stopping the fighting and is blinded with the belief that her fighting is helping despite the deaths caused, while Hao is fully aware of his evil and the true nature of his actions.

Abilities and Powers
Jeanne (likely after manga only character Lady Sati) has the level of furyoku (spirit power) closest to Hao, making her more powerful than she appears. However, she loses all of her powers after Shamash is devoured by the Spirit of Fire. Also it would appear she can endure a lot of pain due to the time she spends with her torturing devices inside the the iron maiden.

Spirit

 * See More: Shamash

Jeanne's guardian ghost is Shamash (known as "Mash" in the English Anime), the Babylonian god of justice. Shamash is the key to opening the Gate of Babylon and appears as a very tiny strange looking creature that proves to have immense power. Her attempt to open the Gate of Babylon to seal away Hao fails and almost cost Jeanne her life.

In the manga, when Tao Ren is killed, Shamash revives him with a kiss on the lips (much to Ren's dislike). Jeanne compares the method of resurrection she used with Shamash to the story of Sleeping Beauty.

Iron Maiden
She spends nearly all her time inside an iron maiden in order to increase her strength by keeping her in a near death state. She rarely leaves it unless she is desperately needed, believing her suffering will bring justice to the world. Her iron maiden, however, was crushed most likely beyond repair.

Past
In the manga, it is revealed that Jeanne was not actually a savior with an omnipotent type of purity. She was an orphan girl taken by the original leader of the X-Laws, Luchist, who, alongside Marco, raised her to believe she was a holy person, who was destined to destroy Hao. Jeanne, herself, is nothing more than an ordinary girl who was granted shamanic powers, and a strong guardian ghost.

Little is known about Jeanne's history or family situation. The series states that Jeanne was a French country girl with shaman powers, who received a divine revelation at the age of ten while praying in a Catholic church. A cross of light appeared and a mysterious voice revealed to her the world was to be destroyed unless it was purged of an evil force. Recognizing the evil force to be Asakura Hao, Jeanne chose to become a shaman.

Shaman Fights First Round
She later entered the shaman fight but not is known about what she did. What is known is that she won the two matches and went to the next round.

Shaman Fights Second Round
She got on the plane headed to the Patch village and ended up somewhere in the American west. Not much is known on what she did or how she even got to the village. She did beat the three month time limit and teamed with Marco and Lyserg to create the X-1 team. Her team was paired against the Nile team. Lyserg started that match but stopped since he could not kill. Jeanne stepped up by hitting lyserg. Just before Marco opened the Iron Maiden everyone took notice of her massive spirit power. Marco opened the Maiden and revealed her. She oversouled the maiden and quickly traps and kills Anatel. She then traps Kahfre and Nakht imploring to stop and stop sinning. The last of the Nile's are so hung up on their dead friend that they did not know what she means. Jeanne feels sorry for them and kills them easily ending the match.

Asakura Hao's Attack
She is attacked alongside Marco and Lyserg Diethel by Anahol, the brother of a Anatel who was killed by Jeanne during the first round of the Shaman Fight. She defeats him and kills him.

Invading the Plants
She went to the plants to try to stop Hao. She helped Lyserg defeat Bron and when Ren was killed by Bron she brought back him back again using the last of her power. She was last seen waiting at the Plant of the Valley powerless hoping Hao would be defeated.

Funbari No Uta
Thoguh she did not make any appearance at Funbari No Uta. Her Iron maiden can be briefly seen in a room similar to a torture dungeon during the Middle Ages. Whether if she is still inside it or not is not mentioned.

Gate of Babylon
The events concerning the Gate of Babylon occur in the anime only.

The ultimate purpose of the X-Laws is the opening of the Gate of Babylon, which is supposedly able to seal away the great shaman Hao. Midway through the series, the Gate of Babylon was introduced to the protagonists, who were puzzled by its meaning.

When the gate is opened, anything and everything within a sizable radius is completely consumed by the Gate, which is actually a gigantic portal. Once through, the trapped will be forced to wander the bizarre environment for eternity. At first, the entire X-Laws, Jeanne, and the protagonists were engulfed by the portal and trapped. However, Hao simply breaks out of the powerful prison as if it were wet tissue paper, as right before he was trapped the Spirit of Fire devoured Shamash, gaining its significant powers.

The prison then proceeds to crumble as Hao breaks out, releasing all the trapped occupants and rendering Jeanne powerless.

Trivia
