Description
Isami Tahara is a central supporting character who serves as one of the primary aides to Hakuto Kunai, the protagonist. He is a 31-year-old man who was summoned to serve as the second male aide and often acts as a mediator among the other aides due to his seniority and level-headed perspective.

At first glance, Isami appears to have a degenerate personality and typically carries a lazy, apathetic attitude, often teasing people with a smirk on his face. This lax expression, however, functions as a kind of poker face, making him difficult for enemies to read or predict. Despite his seemingly lackadaisical demeanor, he is a good person at heart but shows absolutely no mercy to those he considers enemies. His contradictory nature is a key part of his character; he prefers to avoid unnecessary work or massacre, yet he handles his responsibilities with perfect efficiency whenever he chooses to act.

Underlying his casual exterior is the special attribute of genius. He is the only one among Kunai's close subordinates to be labeled as such, and this setting allows him to learn any skill or complete any task with remarkable speed and deliver results far superior to others. This talent extends to interpersonal relationships, as he is skilled at handling people and interpreting the Demon Lord's vague instructions in a way that achieves the desired outcome. This often leaves Kunai scrambling to maintain his image of competence, while Isami simply assumes his leader had a brilliant plan all along.

Isami's most defining and extreme personality trait is his devotion to his younger sister, Manami. He is an intense siscon, to the point where his fixation is described as a disease. He categorizes all women into two groups: his sister Manami, and everyone else, whom he largely dismisses as just numbers. His primary motivation for his hard work and his role within the administration of Ravi Village is to provide for her upbringing. It is stated that he would even plan to conquer the world for just one person, that person being his sister. Furthermore, the prospect of his sister being summoned as a reward for his efforts drives him to become even more active in his duties, and his half-serious prayer for her to be an angel actually results in her gaining angelic powers upon arrival.

In his role within the story, Isami is the dependable right-hand man of Hakuto Kunai. He is the person Kunai trusts the most, as his presence guarantees that security matters are in capable hands. Having once been saved by Kunai alongside his sister, Isami holds a deep sense of gratitude toward him and addresses him as Chief. He is instrumental in the operation and expansion of Ravi Village, working efficiently under Kunai's leadership. His key relationship with fellow aide Yu Kirino is complex; while they rarely come into direct conflict and work well together, Isami harbors a degree of fear towards Kirino, worried that she might harm not only enemies but also allies if it suits her purposes.

Regarding his notable abilities, Isami is a specialist in firearms. He possesses the unique attribute of being loved by all guns in the world, and he is followed by 47 sentient firearms that have their own wills. These guns, which he describes as having severe stalking tendencies, float in the air during battle and unleash storms of bullets in all directions. He can also command individual weapons to perform specific tasks, such as protecting an ally. His fighting style incorporates an arsenal of skills, including rapid-fire barrages, suppressive fire, and explosive grenades. Beyond combat, his survival and non-combat skills are incredibly varied, encompassing medicine, trap disarming, gambling, espionage, and more. His genius ability ensures he masters all these fields with ease. He typically wears a durable Kevlar jacket, carries infinite ammunition, and uses equipment like night vision goggles that enhance his accuracy.
