So, what's the point of hiding the nickname if Ment is going to die anyway? Maybe I'm missing something, but I don't see any other reasonable explanation for what happened.
Zero ultimate on Vishmaster and the "third victim." Vishmaster and the "armless" one also got damaged by Alex Lee, as they went to Ment and Koshe, respectively. Vishmaster died because he lost three actions at once, while the "armless" one and the "third victim" are still alive.
