Klaud Nine

Background
Klaud is the only female Exorcist general. One half of her face is covered by hair, and the other side has burn scars (although in both the second and fourth opening themes and in one scene of the anime, the burn scars do not appear as visible as it does in the manga, appearing as slightly lighter in skin tone on her face). She seems to be a gentle woman, as she is seen weeping for her deceased team.

Edo arc
After her Exorcist team (consisting of Tina Spark, Gwen Frere, and Sol Galen) is eliminated by Tyki Mikk, Klaud returns to the Black Order HQ in order to meet with the other generals. She is then seen paying her respects to members of her unit alongside fellow general Winters Sokaro. Sokaro however, felt more happy to berate his former unit members.

Invasion of HQ arc
Later, she is seen drinking wine with fellow general Cross Marian. Though she asks him why he chose her as a drinking partner, she does not seem entirely unwilling. She does, however, shoot down Marian's advances rather coldly. When the Noah, Lulu Bell, attacks the headquarters, she teams up with Cross, Sokaro, Tiedoll, and Allen Walker to mount a counterattack. Comically she tells Cross to do some work, he says he hates work, so she asks him if he wants to get whipped to which he replies, "Not a bad idea."

Anti-Akuma Weapon
Klaud's Innocence is a little monkey that rides on her shoulder. This Parasitic-type Innocence, called Lau Shimin, is the first sentient Innocence shown in the series. When activated, the monkey transforms into a monster that attacks with balls of energy that form at its fists. Klaud doesn't display this ability until the assault on headquarters by Lulu Bell. Lau Shimin can also convert into a long-range mode, the effects of which have not been clearly demonstrated. In this form, Lau Shimin shows incredible strength, speed, and agility, capable of leaping incredible distances with the greatest of ease. The whip that Klaud holds is possibly an Equipment-type Innocence or simply a means through which she controls Lau Shimin.

Trivia

 * Amazingly, Klaud is the only women thus far that has been immune to Cross's "charms"
