In most espionage stories, agents have backup. In Secret Mission, the Bureau believes that if an agent knows there is an escape hatch, they will hesitate. Hisame has no backup. The intel he gathers is "exclusive" to him alone. If he dies, the secrets die with him. This creates a palpable tension in every chapter, as a single mistake—a misplaced textbook, a glance held too long—cannot be erased by a satellite extraction team.
The file was thin. That was the first red flag.
Agent Kaito Kurose flipped it open inside a silent safe house overlooking the glittering sprawl of Neo-Kyoto. One photograph stared back—a woman in a crimson dress, half-turned, laughing at something just out of frame.
Codename: Himiko
Affiliation: Shogunate Syndicate (underboss to "The Divine Eye")
Threat Level: S-Class
Mission: Infiltrate as her personal security. Extract intel on the syndicate's data vault. Do not engage emotionally. Do not get exclusive.
Do not get exclusive.
Agency slang for forming a one-on-one bond with the target—a bond that compromised judgment.
Kaito smirked. He’d been undercover for six years. Four identities. Two fake deaths. He knew the rules.
“Exclusive,” he murmured, slipping the photo into his inner pocket. “Not in my vocabulary.” secret mission sennyuu sousakan wa zettai ni exclusive
Weeks passed. He learned her rhythms—the way she drank jasmine tea before a negotiation, the single cigarette she smoked after a kill, the rare silence when she thought no one was watching.
She was brutal. Efficient. And lonely.
The agency sent a retrieval order: Extract data by Friday. Terminate contact.
But Friday came, and Kaito found her in her penthouse, not plotting, but staring at the city lights. A cracked photograph in her hand. A child. Hers? A sibling? The file had no mention.
“Ren,” she said softly. “Do you ever wonder what’s real?”
His mission clock ticked.
“Every day,” he answered—truthfully, dangerously.
The narrative focuses heavily on psychological warfare rather than just physical restraint.
An "exclusive" mission would indicate that the operation is of the highest priority, possibly with limited clearance for access. Such missions could involve:
The underground club Rashomon pulsed with bass and secrets. Kaito, now "Ren," ex-MP turned freelance shadow, stood three paces behind Himiko’s velvet rope.
She moved like a predator in stilettos.
“You’re new,” she said without turning, her voice low, amused. “The last one lasted two nights.” In most espionage stories, agents have backup
“I’m not the last one,” Kaito replied.
She pivoted. Her eyes—honey-gold, sharp—scanned him head to toe. Then she smiled. “No. You’re not.”
That first night, she tested him. A rival faction’s knife in the crowd. Kaito disarmed the man so fast witnesses swore he’d teleported. Himiko watched, chin resting on her knuckles.
“Exclusive,” she whispered only to him. “That means you don’t protect anyone else. Just me. Got it, Ren?”
Don't engage emotionally, the file said.
He nodded. “Understood.”
