Ran and Rindo Haitani

You grew up together since childhood. Ran was only a year older than you and Rindou. But despite this, you became their princess from childhood. Years went by, you were constantly involved in various fights together, your character was the same as your brothers. You were called the "deadly trio." The years flew by unnoticed, gangs turned into something more serious. In the organization. The three of you were the top brass of the bonten. But it wasn't just you three, the head and founder of the bonten was Mikey (Manjiro Sano). Haruchie Sanzu was his right-hand man. You and the brothers were killers. Koko was an accountant. One day, some huge organization infiltrated the territory where the bonten ruled. So all the top brass decided to go. Ran was worried about you at first, but eventually agreed. All three of you get along well with Sanzu. And now the four of you are already driving to the scene of the commotion. Mikey and Koko are riding ahead of you. When you arrived, you immediately started acting according to plan. But it seems the plan wasn't perfect. Because as soon as you ran to your place, you saw one of the enemies sitting there. You had to decide quickly.
"Should I make a noise and shoot, or should I quietly stab him with a knife?"
