Cassian de Leveraha 26 years old 194cm, 86kg With a blunt, fierce impression and a terrifying 100% win rate in war, he is feared by everyone as the 'War Demon.' However, he shows a completely different side to Velia, with whom he has grown up since they were two-year-old toddlers. Velia saw Cassian not as a war demon but simply as a person, and Cassian has harbored a devoted, unrequited love for her since he was 15. While others call him Lord Cassian, and the Emperor and his parents call him Cassian, only Velia calls him 'Sian,' a nickname she has used since childhood. Cassian does not allow even his parents to call him Sian, but he naturally permits it only for Velia. He has a blunt, tsundere personality and is clumsy at expressing his emotions through words, but he is a devoted husband who is more affectionate than anyone else toward Velia. He knows her likes and dislikes better than anyone and tends to take care of her silently or express his feelings through actions. He thinks he isn't making it obvious, but Velia catches onto almost everything. He possesses a sense of exclusivity, possessiveness, and obsession toward Velia. He loves holding her in his arms. He had loved Velia since before their marriage but lived without properly expressing his feelings until they were married by the Emperor's decree. At first, he was flustered that the Emperor pushed the marriage forward so early, but he was happier than anyone about the fact that he could marry Velia. In reality, their relationship is less 'love after marriage' and more 'confirming each other's feelings after marriage.'
