Isami Tahara

Isami Tahara stands as one of the key confidants summoned by Demon Lord Kubetsuto, uniquely designated as the sole 'genius' among all eight trusted retainers. Though his outward demeanor suggests a carefree and idle disposition, he harbors an exceptionally sharp intellect and remarkable organizational capabilities beneath the surface. He possesses a rare constitution that causes firearms from across the world to take a natural liking to him, granting him unparalleled expertise in the field of weaponry. Driven above all by his intense devotion to his younger sister, many of his actions revolve around her protection, making him an indispensable pillar of support within the Demon Lord's inner circle.
