Kosuke Kanamori balances high school life with covert operations for the international VN spy network. His dangerous missions require frequent global travel, disrupting academic responsibilities like homework and personal plans such as scheduled dates. He leverages computer hacking skills to pursue international criminals during espionage assignments. One documented mission involved tracking Neo-Nazis to the Arctic, where they attempted to recover a sunken U-boat containing hazardous materials, illustrating the extreme risks of his work.

Kanamori displays typical teenage characteristics: average intelligence, intermittent field incompetence, brash decision-making, and marked naivety. He often ignores protocols in favor of impulsive actions during operations, creating complications that force his handler—also his teacher—to intervene. This reliance on support underscores his dual identity challenges.

Positioned as an audience-insert character, his narrative emphasizes the clash between ordinary adolescent experiences and extraordinary spy scenarios. His portrayal deliberately avoids conventional spy competence tropes, focusing instead on the friction between his conflicting roles.
