Suelecia Zagan Analeit

スーレシア・ザガン・アナレイト
Sue is Slain's younger sister and the second princess of Analeit Kingdom. As Shun’s half-sister, born to a different mother not long after his birth, her talents rival his. Her obsession with her brother Shun is extreme enough to put others off, and she's noticeably hostile toward all girls who get friendly with him. (Source: Official Site)
