Killing Melody?

"What do you think?" The mysterious guy asked his partner. 

"To think that she was able to spot me and almost hit me… it seems that the Renvolt is not lacking any successor. Still, we have tested the machine. Since it works, we can prepare for the next plan. We now know that Tier 3 Beast is not enough to kill him." 

"Well, the Drake Group and the Rusth are supporting us. We can definitely have a blast next time. It's just…"

"Are you concerned about the operator?"

"Yeah. That operator is pretty talented. Erasing the data and removing herself from the equation while still helping them."

"In that case, let's eliminate her." 

"I agree. Killing her is not related to the warning of that old madman, so it should be fine if we target her. However, the problem is that… there is a chance that killing her won't change anything."

"Are you saying that they don't have that relationship?"
