Mismarca Koukoku Monogatari

Mahiro, the prince of the Mismarca Kingdom, avoids studying or training in swordsmanship, preferring to spend his nights playing. His imperial bodyguard, Pariel, frequently reprimands him for his lack of discipline. Meanwhile, an elite unit from the Demonic Kingdom Granmarsenal approaches. Leading the group is Lunas, the third princess of Granmarsenal and a warrior. The vassals of Mismarca prepare for battle, but one individual suggests negotiating instead of engaging in conflict. The kingdom and its prince now face an uncertain future.
