Caius Lao Bistail, first prince of Tildant—a nation of titans in the world of Eustil—stands taller than his kin, a testament to his royal lineage. His dark brown skin contrasts with striking purple eyes and short blonde hair that cascades into a long ponytail. He dresses in regal splendor: a red-and-white cloak drapes over a white-and-gold uniform, cinched by a black sash, while golden shoes complete his imposing stature. Raised to believe a king’s prosperity hinges on a trusted queen, Caius endured a shattered betrothal to childhood friend Medina after an oracle foretold calamity should he wed a Eustil native. Undeterred, he delved into summoning magic, determined to conjure a bride from beyond his world. This relentless pursuit underscores his resolve to honor tradition while securing Tildant’s future. Caius balances open-hearted devotion with a steely edge. He shields loved ones fiercely, defending Medina from slights and safeguarding Koichi, a non-titan companion. Yet he turns ruthless against foes, confronting threats headlong during perilous quests. His courtship of Koichi blends pragmatism and tenderness: a one-month trial contract offers autonomy, while quiet gestures—admiring Koichi’s intellect, compassion, and tenacity—reveal deepening affection. As Tildant’s foremost titan knight, Caius wields unmatched physical prowess, immune to toxins like the Karina fruit’s venom. His magic spans summoning rituals and shrewd defenses, such as weaving detection spells into garments to track allies. Preferring action over delegation, he personally retrieves rare cures like the Raisa fruit, risking himself to protect others. Caius champions love’s power to transcend boundaries—species, gender, or origin. Emotional bonds, he argues, outweigh societal dictates, a conviction fueling his bond with Koichi, whom he deems a destined partner. Diplomatic exchanges with beastmen and clashes with political rivals further showcase his tactical acumen and unwavering dedication to peace. Once bound by tradition, Caius now defies prophecies and expectations, evolving into a leader who melds duty with heart. His journey—a struggle to harmonize crown and connection—weaves a tale of resilience, love’s transformative force, and the price of forging one’s path.
