Lulu Bell/History

Original Lustol
Like all Noah, the first Lustol assisted the millennium earl during his battle against Innocence. When he was defeated and the earth was submerged, Lustol found refuge in the Noah's Ark and there bred, becoming one of the twelve ancestors of mankind.

Previous Lustol
The previous Lustol was killed by Nea D. Campbell 35 years before the beginning of the story.

History
At some point of her life she awakened as a Noah and swore loyalty to the Earl of Millennium. Her awkward talking maybe caused by a particular childhood.

The Black Order Attempted Annihilation Incident arc
Lulu Bell is first seen, briefly, during a family meeting, when the Earl of Millennium decides to make his first move against the Black Order in some time.

Lulu Bell's Attack arc
The Earl orders Lulu Bell to eliminate the exorcists Allen, Lavi, Lenalee and Krory, who are searching for Cross Marian. She has to stop them from reuniting with Cross. She starts by disguising as Lenalee to lure Krory and kill him, but the other exorcists notice Krory missing and go after him. When they meet up with him they find out that there are two Lenalees. The exorcists get separated, Allen and Krory, Lavi and Lenalee. When Allen and Krory get separated, Lulu Bell's attacks mostly focus on them. The exorcists eventually reunite.

The Crystal Girl arc
After the Earl found out about the Innocence of Mei-Ling, he ordered Lulu Bell to destroy it, which she did successfully ending her path before becoming an official Exorcist. But in the process of doing that, Lulu Bell's Akuma servant died.

Noah's Ark arc
When the Earl's download of the information of Noah's Ark seems assured, Lulu Bell is seen arriving through one of Road's doors and asking if the Earl is really so worried about the Fourteenth that he'd go to the lengths of destroying the Ark go get rid of him. When the Earl asks her what she means, Lulu Bell points out that, while he is celebrating, he is also crying an seems sad. Then, when Allen manages to use the piano in the room Cross Marian sent him to cancel the download and stabilize the old Ark, leaving the new one the Earl was attempting to create incomplete, Lulu Bell notes that eighty percent of the data was lost and that the destabilization of their attempts must have been what Cross had been after.

Invasion of the Black Order arc
Not long after the Earl's failure to completely download the Ark, Lulu Bell is sent to infiltrate the Black Order European Branch, killing and disguising herself as Oceanian Branch Head Andrew Nansen to sneak in. Once she is inside and is in Laboratory 5 and within reach of the Akuma Egg, she attacks and seriously injures Johnny Gill while shedding her disguise and opening up an Ark Gate to let in an army of Level 3 Akuma that have been sent to accompany her. As her Akuma begin to attack, Lulu Bell calmly introduces herself to the panicked scientists, remarking that the Earl has always told her to be polite.

After her Akuma have immobilized most of the scientists and lined them up to the Skulls can begin sorting through them, Lulu Bell goes to the Akuma Egg and presses herself to it, embracing it. When Allen Walker and Bookman arrive via their own Ark Gate, Lulu Bell lets her Akuma handle them while opening a black Ark Gate, planning to withdraw once they have secured the Akuma Egg. Then, when Allen is captured by several Level 3 Akuma, Lulu Bell goes over to him and strikes him, knocking him out and cancelling his Crowned Clown invocation before remarking that they'll take him with them when they leave. After she orders the withdrawal of their units, ordering the rest of the scientists in the lab to be killed, she lets an Akuma drop her into the black Ark Gate along with the Egg, but before the Egg can be taken, Miranda Lotto arrives and pulls it back into the lab with her Time Record, and when Komui Lee orders the Egg's destruction and the Generals prepare to comply, Lulu Bell comes back and traps Miranda within her water form, demanding that she release her invocation.

As the Generals begin to fight Lulu Bell, she protects it, but is unable to keep them from damaging it. Lulu Bell then tries to use Miranda as a hostage to keep the Generals from damaging the Egg further, but when that doesn't work and the Exorcists attack with their full power, Lulu Bell is forced to revert back into her human form as the Egg sinks into her Ark Gate. She notices a white spot on the Egg's surface, though, and, realizing it is Allen, she screams out at him to not damage the Egg further, calling Allen a bastard as he destroys the Egg and flees back to the laboratory with Miranda.

Once she has returned to the Noah Family, Lulu Bell, distraught by her failure, locks herself away, and is noted by Road to have been "weeping pitifully."

In the anime she is seen next to the Earl at the party he is hosting and commenting on their future plans.

Artificial Exorcists arc
When the Noah Family was gathered together, Lulu Bell is shown among them in the form of a black panther. During the assault on the North American Branch, Lulu Bell is seen in Greece in the form of a dragon, facing off against Klaud Nine, Lenalee Lee, Goushi and Timothy Hearst. As the Noah retreat, Lulu Bell taunts Lenalee and the others, telling them that Allen will soon become a Noah and that they can either believe in a Noah or destroy Allen like they had been forced to the Third Exorcists.
