Claire

Mark and Claire are the first Akuma to appear in the series.

Appearance
Mark is a priest with brown hair, while Claire is a nun. When becoming an Akuma, Claire takes the form of a round-shaped creature with multiple gun barrels. Her soul is chained down to the machine, with extreme anguish and a somewhat distorted face.

Personality
Mark was a kind-hearted priest who chose to believe in God, and persuaded Claire and Moa to do the same, until Claire's death. When Claire died, Mark becomes hateful towards God and curses him in hatred.

The Akuma Claire is silent and talks in a slow, emotionless voice, typical of a Level 1 Akuma. She is absolutely obedient to the Noah Family, and kills humans to continue to evolve.

Background
Claire and her younger sister Moa's parents were killed by Akuma at their young age. Mark, a priest of a catholic church, then took care of the two. Claire eventually fell in love with Mark, and the two got married. When Moa decided to become a police officer to arrest the criminals responsible for her parents' death (not knowing about the Akuma at that time), Claire was against it, and the two had an argument. Mark managed to have the two reconcile, and to believe in God, when an iron cross fell from the top of the church and skewered Claire. Mark then cursed God in his extreme anguish.

It is then the Millennium Earl approached Mark, offering to bring Claire back as an Akuma, to which the unknowing Mark agreed. At first overjoyed, Clarie immediately angrily shouted at Mark for cursing her to the Earl's services. The Earl ordered Claire to kill Mark and wear his skin, to which she could not defy. Ever since then, Claire killed people under the Earl's orders.

Synopsis
Mark was first seen in a room, with the Millennium Earl. The Earl was telling him to kill more. After Allen explained to Moa what is an Akuma, he appeared in the room and turned into the Akuma form, shocking Moa. After she and Allen arrived at the church, Moa saw the Akuma kill all the detectives. Allen eventually destroys her and she thanks Allen for freeing her.

Akuma Blood Bullets
As a Level 1 Akuma, Claire can only shoot viral-laced bullets that causes her victims to crumble.
