Belnika is a kind girl and has a personality very similar to Elie only much more shy. She was experimented on so that she could have magical powers.
They tried to give her the power of Etherion, so that she could help Hardner in his plan to merge with Endless. They kept the truth from Belnika, telling her she would be helping the world. After discovering Hardner's true intentions, she sides with Haru. However, as it turns out, Belnika never attained the power of Etherion, although she does possess a large amount of magical power. She has the power to negate any magic around her. She also seems to have some feelings for Haru although she does not show it much.
