5th place: The Insipid Prince's Furtive Grab for The Throne Vol.15

The next covert operation—Command the Empire’s greatest forces and take down the magic sword wielder!

One year after becoming Prime Minister of his domain, Al returns to the imperial capital—only to be handed a top-secret mission by Arida, Captain of the Imperial Guard.
“You may use the three here as your pawns. Set a trap to create a two-on-one situation. We’ll overwhelm them from a position of strength. This is your specialty, isn’t it?”
The target: a dangerous rogue magic swordsman who’s infiltrated the capital!?

Al is tasked with leading a battle beyond reason: the Empire’s three strongest warriors—Arida, Theodore, and Elna—versus a wandering swordsman wielding one of the most powerful magic blades on the continent.
But this battle also ties into a 500-year-old grudge between House Yūshaku and a mysterious clan—igniting a new conflict between the Hero and Kūmetsu!

The web of schemes spun by the strongest prince continues—Vol. 15 of this high-stakes political fantasy!
