Artai
Nagi Daí Artai - Still the Grand Duke of Artai. He is pledged to wed Mashiro. Initially he comes across as even more cruel than the anime version, having destroyed entire nations because of the misbehavior of one or two representatives and treating the Otome as below himself. However later developments show a kinder side. This is a reversal from the anime's Nagi, who initially seemed benevolent but later revealed sinister intent. Eventually he sacrifices himself to save Manshiro from Mikoto's attack and dies.
Arashi Daí Artai - Nagi's little sibling, whose ambitions were to continue her older brother's dreams.
Marie Antoinette - One of Arashi's most trusted soldiers. Seems to be engaged with a yuri relationship with Yang Guifei. Wields a thorned whip in combat.
