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.

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 seems to be immortal and does not age noticeably between Teresa's childhood and the new arc.

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 was also the one sent to gather Rafaela from exile after the death of Teresa to prepare for the war with the Abyssal ones.

Clare's Time
Rubel made a few appearances during Clare's time as a Claymore. He was usually giving Clare future missions and was also responsible for collecting the pay afterwards. He is also the one who hands Clare the Black Card sent to her from Elena. He comments on how Clare travelling alongside Raki is similar to Teresa travelling with Clare and warns her it may lead to her downfall.

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 orginization 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.

Etymology
His name was changed in the English version, by replacing the ヴ (vu) with a "be", it is unknown whether this is due to a misreading of the Katakana or intentional. He seems to be named after the Louvre Museum (ルーヴル Rūvuru in Katakana). Apparently all the members of the organization are named after popular art museums around the world.
