Tumisen, as an assassin, roamed the world unmatched and unopposed, even slaying members of the Sacred Order.
But as a military commander and leader, he produced only blunders and could never understand why what he did was always wrong and what the right approach was.
This was why Menilman sent him to assist Charles, who needed members of the Sacred Order, and commanders were even more crucial in sea battles—especially at that time when Menilman only had a single Magical Alchemy Warship.
The Beastmen had occupied all the cities in the Red Dragon Sea, but most Beastmen had retreated to a camp in the middle of the Red Dragon Sea, with few remaining in Dubrovnik.
Charles personally led the Labyrinth Guardians in an assault on Dubrovnik, where the few thousand Beastmen there only managed to resist for half an hour before completely collapsing. After hundreds were killed, the rest chose to surrender.
