Bel Glan Artai, reigning Archduke of Artai, governs as a shrewd yet self-indulgent sovereign whose political acumen forges a strategic treaty with Taiyuan—securing Princess Sakura Hazakura as his contracted Meister Otome to solidify their alliance. His court teems with personal excess, housing six consorts and siring over ten heirs, a legacy marred by familial rivalries that erode national stability.

His sudden demise ignites a tumultuous succession crisis, unraveling Artai’s political order and spawning a vacuum that intensifies regional power struggles. Subtle narrative cues and design motifs allude to a potential bloodline connection to Mashiro, though unconfirmed within existing records.

As Sakura’s master, Bel Glan epitomizes the Otome system’s role in binding nations through calculated alliances, his reign a precarious balance between decadence and duty. The chaos following his death becomes a pivotal catalyst, steering geopolitical tides as rival factions vie for dominance in Artai’s fractured landscape.
