Second generation leader of the Baji family. In order to get the throne, he used what ever dirty methods he could, but he never received any love from his family.
Nagi was in love with Lucaria's mother, Yodaka, who didn't see him as one of the Baji family, but as one of his comrades. She was the only one seeing his true nature, knowing he's afraid of war, and just forcing himself up to the front lines. Nagi's hatred towards the royal family grew as the girl was weakened by the love towards the King and soon was exiled from the country. He saw Yodaka in Luca, but couldn't stop hating him as he's the son of the man who'd stolen his love.
