Mismarca Koukoku Monogatari

Mahiro, the prince of a kingdom, avoids studying or training in swordsmanship, preferring to spend his nights playing. His bodyguard, Pariel, frequently reprimands him for his lack of discipline. Meanwhile, a squad from the demonic kingdom of Granmarsenal approaches. Leading the group is Lunas, the third princess of Granmarsenal. The kingdom’s vassals prepare for battle, but one voice suggests seeking peaceful dialogue. The kingdom and its unprepared prince face an uncertain future.
