I Started It, Then Dumped the Executive

My name is Kawakami Saki. My real name is Joanna, and I'm currently being hunted by the Port Mafia executive known as Hat Guy. Why he's after me goes back seven years... I was born in Italy several centuries ago. I was the lover of the current tutor to the tenth Vongola boss, assassinated the ninth Vongola boss, and later joined the famous assassination squad Varia. Along the way, I also deceived the feelings of a certain Hat Guy, back before he became an executive. Anyway, back to the point. To get the secret of the bandage guy who retired from the executive position, I'm now working undercover at the Armed Detective Agency. My cover was going perfectly, until one little mishap just before I could succeed... I accidentally got trapped inside a novel written by a detective with a penchant for raccoons. The only way to get back to reality is to identify five hundred murderers among a thousand people. Inspired by the Detective Agency, I decided to lie low in the book's world, make a fortune, and reach the pinnacle of life. But one day, a new player suddenly dropped from the sky and smashed my apartment to pieces... As our eyes met, I knew I couldn't keep playing this game. Hat Guy, whom I had once deceived and abandoned, and who thinks I'm "one of the five hundred murderers," is planning to hunt me down. *Pairing with Chuuya. The heroine's real name is Joanna.

Takigawa Yuichi had a dream. In it, he fell out with his friend Byakuran Gesso and became the Port Mafia's fifth executive. His ability was like a human, self-propelled wrecking machine: everyone he looked at became dirt poor. In the dream, Takigawa Yuichi watched his wealthy self shoot the boss in the head, live a life of luxury with lovers on both arms, and party every night. He even made the bandage boy, who had jumped into a river two days earlier and dragged him in too, dance the Soran Bushi. In the dream, he died at twenty-eight, betrayed by another executive. That was Takigawa Yuichi's short life. Takigawa Yuichi woke up in a panic with a rehabilitation System in his head. Rehabilitation System: This is the life you'll have in the future, Host. This System is dedicated to preventing you from meeting the same miserable end. First, please avoid Yokohama. Takigawa Yuichi laid railroad tracks all night, then carried a train all the way to Yokohama. "Don't turn down a chance to get rich. I love Yokohama, and Yokohama loves me." Rehabilitation System: Listen, Host. You think you need money, but you don't. What you need is a happy family, the joy of working... Takigawa Yuichi: And the joy of bathing in a pile of money! Rehabilitation System: Are you stupid? Takigawa Yuichi: You're the stupid one! If I take out the bandage boy, the red-haired woman, and the short guy with auburn hair, my happy life will never end! Rehabilitation System: ... Standing in front of the Port Mafia skyscraper, Takigawa Yuichi rubbed his chin and set himself a small goal to achieve his grand ambitions. The first step to getting rich was, first of all... A coup. A takeover. A throne seized by force! Theme: Through struggle, the heroine learns what it means to have companions, and finds the real motivation to keep living.
