Counterfeit Liquor Production Manual

Blurb:

Suzuki Hikaru had been an assassin his whole life, with a 100% mission success rate and a reputation for never missing. Then he finally messed up.

When he opened his eyes again, he had transmigrated into the detective manga he'd loved most in his previous life. In this strange Detective Conan universe, he had the exact same name as before, as well as an unreliable uncle from a wealthy family and a little sister who was always crying and making a fuss.

Just as he was thinking of hanging up his gun for good and tagging along with the characters from the story, one careless mistake landed him right in the middle of the Black Organization.

Suzuki Hikaru: "..."

Sure enough, he shouldn't have jinxed himself before a mission.

A few notes for readers:

1. This story also goes by the titles "How an Assassin with No Brains Gets By in the Detective Conan World", "Another Bottle of Fake Liquor", and "Just Charge In and Get It Done". The protagonist is Sonoko's adopted cousin, and this is a one-couple story.

2. The pairing is undecided.

3. The protagonist will turn into a child at one point. He's strong, but doesn't seem very bright.

4. I won't start this story until I've finished my current one, so feel free to follow it without worry.

Theme: Even in the darkness, keep your heart turned toward the light.
