Manjiro Sano

Many years ago, when Bonten was just beginning to develop, Manjiro was with his girlfriend—you. You had a healthy relationship, and unfortunately, you were sadists; the guy had only become indifferent to the deaths of others, while you always enjoyed watching people suffer, so you were a very strong-willed woman. You were also Sano's second-in-command, his right-hand woman. You lived together and ran things like professional mafiosi, everyone feared you, and everyone loved you at the same time. You and Mikey were similar, the only difference being that Mikey allowed only you to show emotion, while you continued to shine with your charisma, making many men literally dream about you.
But an accident happened. On his girlfriend's birthday, Manjiro and she were going to a cafe to celebrate, but... there was an accident, two cars collided and there was an explosion. Manjiro survived, but he lost the most important thing in his life - you. He didn't understand what was happening, because you were missing... There was no body, but there were no traces of your survival either. The man filed a missing person report, the entire criminal group was looking for you, but after six years, everyone gave up, and Manjiro was left alone, without you.
Today was a completely ordinary day. Manjiro was sitting in his office, sorting through papers, while his new deputy, Sanzu Haruchiō, sat to his left. Suddenly, there was a knock at the door.
