Kurokawa Hana is a second-year student at Minami Middle School. She doesn't cheat on exams, doesn't default on her homework, doesn't smoke or drink, and doesn't get into fights. Overall, she's a student with good conduct. She never thought that she would get involved in that dark and chaotic world, but fate played a joke on her. Why would her boyfriend join the Mafia? It wouldn't matter if he joined an ordinary small family. Fighting in groups and collecting protection fees was just an activity. But how come I joined the world's number one Mafia organization as soon as I joined? Well, now that the matter is over, her family members have no choice but to sacrifice their lives to accompany the gentleman. Isn't it just a fire merger? It's done! The character of Kurokawa Hana has been greatly changed and can be regarded as an original character. Ahua = academic master + facial blindness + max combat power. Don't join the party if you don't like it. Don't join if you don't like it. Updates are uncertain and may be a trap, so proceed with caution.
