Caim

Prior to the fall of Caerleon, Caim was said to be a cheerful type, good in combat and being on good terms with Inuart and Furiae. He also dearly loved his parents. After the fall of Caerleon and the death of his parents at the hands of Empire, Caim developed an intense desire for revenge. His condition worsened after Furiae was chosen as the new Goddess of the Seal, with him losing any remnants of his cheerful self and becoming sullen even in front of Furiae. His darkened demeanor also greatly affected Inuart, whose own withdraw was reinforced by this. By the events of Drakengard, Caim is known for his bloodlust and vengeful ambition. He lacks empathy and mercy, such as having no hesitance to take many lives, and displays a great love for battle and slaughter, as he is shown to have a sadistic grin when in the midst of combat.

Despite his grim persona, he also possesses a softer side. He has shown compassion towards his sister, Furiae, and many times puts her safety above his own penchant for revenge. He even has an attachment to Inuart, which remains to a degree despite his friend turning against him. Caim also develops a strong bond with Angelus over the course of their adventure. This eventually evolves into a kind of romantic attachment, which is demonstrated with his shedding tears when she becomes the new Goddess in Drakengard's first ending and his sorrow at needing to fight her in the third.
