Rubel

Rubel (or Louvre in the original Japanese version) is the member of the Organization that is in charge of controlling and giving missions to Clare.

Etymology
"Rubel" is derived from "Ruvuru," (ルヴル, pronounced ruvuru), a Japanese transliteration of the French "Louvre."

His name is changed in English translations of manga and anime, by replacing the ヴ (vu) with a "be", it is unknown whether this is due to a misreading of the Katakana or intentional. The Louvre is an art museum in Paris. Organization members appear to be named after art museums.

Appearance
Rubel is a tall, thin man who is always seen wearing a pair of dark sunglasses, a black hat and a black suit. He also has a rather pointed nose and is completely bald underneath the hat. He shows no signs of aging from the time of Teresa's childhood to the present day.

Personality
A cunning person, Rubel often manipulates events to his own ends, withholding or providing knowledge to encourage people to act in a way that benefits him and his goals. He takes the role of an observer, not directly acting in favor of nudging with information and letting others act on it however they decide, so that he can claim a lack of involvement in their actions and keep his cover as a spy within the Organization.

He often likes to tease who he's talking to, and seems to take a more personal interest in Claymore than most handlers for the Organization.

Teresa's Time
Rubel was a handler as far back as Teresa's time as No. 1. After Teresa was killed by Priscilla, Clare brought her head to Rubel and asked to become a Claymore using the flesh of Teresa. Rubel agreed and entered Clare into the Organization.

Rubel also retrieved Rafaela from exile after the death of Teresa to prepare for the war with the Abyssal Ones.

Clare's Time
Rubel gives Clare assignments and collects fees. He gives Clare Elena's Black Card. He warns both Clare and Raki about their friendship, predicting heartbreak for both.

After Seven Years
When he confronts Clare, Cynthia and Yuma in the new arc, Cynthia deducts that he is a spy from the enemies of the Organization. Rubel confirms and admits he is aiming at destroying the Organization from the inside and that he was Miria's "inside man" who told her about the mainland. He also admits to hiding the fact of partial awakened Claymores from the Organization since he considers it a step in the Organization developing controllable Awakened Beings. When he brings up Renee is captured by Riful, Clare realizes his aim of setting up all the partially awakened Claymores to die by Riful's hands.

As Miria appeared at the Organization's headquarters and immobilized all the Claymores there, one of the observers stated how much it was disgrace for this to happen. However, Rubel walked up behind him, saying that they should compliment the intruder's (Miria's) abilities, stating that dealing all the Claymores such devastating blows while only immobilizing them is something that is only possible to someone via a large gap of power. After the Organization sends out the twins to take on Miria, Rubel says that even though the twins have no number, it is best to "think of them as natural beings, to come after Alicia and Beth." During the fight, Rubel states that even though Miria can take them both on now, they are not the Organization's Trump Card. Later, Rubel is seen talking to Dae about the resurrection of former Number One's. After all three revived warriors awaken in the battle between Miria ad the current warriors, Rubel deduces that Dae knew they would awaken all along.
