[Crossover] Surrounded by Men After Eloping

[I've changed the upcoming story. I really couldn't write the previous one.] Akita Shinya once had a marriage arrangement. His betrothed was Illumi, the eldest child of a notorious family of assassins. He had met her once. The eldest daughter had fair skin, smooth long hair, a steady temperament, and considerable ability. He thought he was completely out of her league. Only later did he find out he'd gotten the gender wrong: that was a man. The eldest daughter had become the eldest son. So he ran away from home, took the name Akita Shinya, forged an identity, and started working three jobs a day to put himself through university. As soon as he graduated, he immediately passed the exam to join the Tokyo Metropolitan Police Department's Traffic Division, becoming Tokyo's most dreaded ticket-writing menace. He absolutely loves handing out tickets. Akita Shinya's dream is simple: earn enough to retire before turning thirty, and work up enough courage to ask his betrothed to call off the engagement. But his life of writing tickets came to an end the moment he found that strange child. First, the owner of the Porsche he'd kept ticketing showed up at his door. Then a hot, white-haired teacher started barging into his home every day asking for food. A black-haired cult leader even tried to recruit him every single day. And the police officer who lived nearby and dealt with illegal drugs watched him receive visitors day after day, his gaze growing more and more unsettling! When all the men gathered in one place, his fiance climbed in through a window on the nineteenth floor. "Come back with me. We're getting married." P.S.: 1. A crossover, the strange child is Boss Dazai. Slice of life. 2. It crosses over with many series. The main world is Detective Conan plus various sports anime. Characters who died in other supernatural-ability series are reincarnated here to live. 3. It will also cross over with supernatural-ability series, such as Hunter x Hunter and Jujutsu Kaisen. Most of the characters are from alternate timelines, and the protagonist's main world suppresses the other supernatural-ability worlds. For example, there are fewer cursed spirits in Jujutsu Kaisen, and their grades are lower. Theme: Retirement takes a lot of hard work
