Armor: Sin of Friday
Carossa is a member of the Claw Man's society and the twin brother of Meryssa, though he is far more aggressive and rash than she is. Whenever they are together, he is always the one who takes the initiative. Both he and Meryssa were orphans, and as such, he has developed a deep need for attention, especially from the Claw Man. He is also very protective of his sister and will attack anyone who scares her or makes her cry. Nearly from the beginning, he develops a growing sense of animosity toward Michael, partly because Michael becomes the center of the Claw Man's attention (due to his importance in his plan) and partly because Meryssa develops a crush on him. Both siblings are members of The Original Seven.
