The Country is full of crime, ever since I was young, it was impossible to not encounter them at least 4 times a week.

"I didn't live a second life just to become the sidekick of the "World's finest Detective!"

After reincarnating to a world that's reminiscent of those of the 1940s to 1950s: Film-Noir & Mafia Movies. Elio must adapt to a new life, where crimes and mystery lurk in every corner.
