After serving the bandage freak for a while: The bandage freak: Which organization sent this guy undercover? He's terrible at it. The famous detective next door: Well, you've only got six months left undercover anyway... Ogino Shigeru: Don't say it so plainly! At the distillery, Ogino Shigeru decided to be more conspicuous. His calling card was wiping out a mid-sized organization. A certain blond, dark-skinned undercover agent: Whiskey is extremely dangerous. Ogino Shigeru: Jin-chan. Jin-chan: Go to hell. A certain elementary schooler: I saw that familiar guy go into Whiskey's home. Those two vicious criminals must be plotting something terrible. An undercover agent who'd seen some strange things: Maybe they just want to have dinner? A certain elementary schooler: ???????????????? The Vongola Outside advisor: Idiot! Was going undercover supposed to be some kind of thrill ride? The Tenth: I'm done. Forget it. The protagonist is an ability user, with the ability Mirror Image. The protagonist is the pursuer. The story's message: Justice will always triumph over evil.
