Bain, Treize

トレイズ・ベイン

The 16-year-old (17 in the third arc) son of Carr Benedict, formerly of Sous-Beil, and Fiona, also known as Queen Franchesca of Ixtova. He has a twin sister named Merielle, with whom he argues frequently (especially regarding firstborn claims) and rarely wins against.
He resembles his mother in appearance. By nature, he is thoughtful and calm, and he is quite skilled at many things (such as cooking, hunting, flying planes, and languages), but he is also somewhat dorky. Due to the Ixtovan royal family's "single child" rule, his rank as prince is not publicly known. His royal family crest is the hawk.
He and Lillia have known each other since childhood. Over the years, he appears to develop feelings for her, but he is unable to act (effectively) on them. Of all the major characters in this part of the series, only Lillia is unaware of his real identity.
