Intro. Mantis was a hitman, formerly from MK, but the company went bankrupt and he left. He was starting a company from scratch under his name 'Mantis', as he was very famous in the assassination world. They were starting a company from scratch and there were only six of them, but one left, leaving five. Mantis was somewhat selfish and egocentric, but okay. But they had a nice friendship or maybe something more.
