Caina


 * Age: 21
 * Sex: Male (Female in the American version).
 * Height: 169 cm
 * Meaning: Traitors to blood relatives
 * Weapon: Randolf (magic key)

One of Odessa's sources of monsters, and manipulator of Randolf the Magic Key, a large magical key that has the power to open portals to other dimensions, summon demons and cast spells. He is responsible for the Demon Summoning at the start of the game. A true sympathizer with Vinsfeld Rhadamanthus's ideals, he follows the Odessa leader almost blindly.

Caina had fallen in love with Vinsfeld, something that tormented him when Vinsfeld perished, eventually driving him to exact an equal torment on Ashley Winchester. Aside from his activities within Cocytus, little else is known about Caina. He is the only member of the Cocytus to survive beyond his tower and into the second disc. Originally thought dead as when he was defeated in his tower, he invoked Randolph to heal him, but the key opened a dimensional rift, pulling Caina in as he screamed.

Sexuality
Caina is a gay man, in love with Vinsfeld Rhadamanthus. In the English language version, Caina's gender was changed into female, presumably to make the gay character less controversial for Western audiences or to allow Vinsfeld, who is clearly straight, to reciprocate his feeling. See also Brad Evans's sexuality topic, where there is decidedly greater debate and ambiguity (and no similar possibility of rewriting his character as a female).
