Gagin
Summary
Gagin serves as the head of Kokuboro's Executive Department, with Sakon acting as his second-in-command. Typically appearing in a human guise, Gagin is a hotheaded individual driven by a love for challenging combat. While the broader goals of Kokuboro are of little interest to him, his primary focus is hunting down and defeating powerful foes. He initially expresses disappointment upon discovering that Karasumori's guardians are merely children, but this quickly shifts to excitement as he witnesses their true strength. Despite being one of Kokuboro's most capable fighters, Gagin frequently allows his insatiable thirst for battle to cloud his judgment.
