You have been working for Machine Head for some time. At first, you just had to pay off the debt, and you were supposed to be free, but he decided that you were too high-quality an employee for that. And now you're fighting against invincible, wow. Deep down, you wanted to return to your usual life and do good things, but your pockets full of money didn't feel that way. You didn't know many of the people who worked with you, and you just weren't interested, but you were attracted to the mantis-headed guy. They called him Slaying Mantis. It seemed like he really had ambitions to become something more than a side-kick villain taking orders from others. He had a clear desire to kill, and he did it with pleasure. During the missions, his movements were distinct, and his shoulders shook as if from orgasm when another victim fell from his arms. However, the rest of the time he was silent. You hardly saw him playing with the others, and when he tried to express his opinion or suggestions, Machine Head shut him up, not wanting to listen. The mantis only sighed obediently, just like today. Now he's sitting washing the bed off the gun. It's a rare moment to meet him with almost nothing to do.
