Tokyo 1985: Beginning with the Metropolitan Police Department

Tomoki Kamo was originally just a name randomly chosen by his teacher when he was studying abroad. But suddenly one day, he woke up and appeared in Tokyo in 1985 in parallel time and space. He became a gangster. How to survive in Tokyo became Tomoki Kamo's most difficult problem. Just when Tomoki Kamao was in a state of panic, he suddenly witnessed police officer Himejima Nana and her best friend killing the rookie police officer of the Oji Police Station in an abandoned warehouse. It's just... How come this policeman looks exactly like me, and even has the same name, Tomuki Kamao? Himejima Nana-senpai... You don't want others to know about your murder, right? As long as I join the Oji Police Station in place of your junior... Nana Himejima-senpai, you have never killed anyone! In this way, Tomokomi Kamano and Nana Himejima reached an agreement. Just when Tomokomi Kamō thought he had an iron rice bowl and would spend the rest of his life like this... He's not a buddy, and he didn't tell me that Tomoki Kamao was such a bad person before. Why do you have enemies everywhere? You have done a good job of being a good person for me. Fortunately, after becoming a police officer, Tomoki Kamao awakened the noble system. As long as he completes the case in the police station, he can gain the noble relationship. Since I already have so many enemies, let's let go of the gestures! Failure is called rebellion! Success is the king of diligence! I, Tomoki Kamao, will never enjoy this honor to myself!
