Mr. Spy Establishes An Intelligence Agency In Another World

"Terrorists planning to blow up a VIP? Just kill the terrorists first." "Powerful corrupt noble making backdoor dealings with the enemy? Make his death look like an accident to avoid political unrest." "Monsters terrorizing the countryside? Test out our latest chemical weapons on them." "Enemy nation planning to invade? Get some blackmail on them." "Demon King planning on destroying the world? Just break every law in the Geneva Convention and send them packing." This is the story of how a modern-day spy got summoned to another world and established an intelligence agency (and plans on conquering the world for Earth.)
