The instant Noboru heard "Vinross-Yu Cranker Materials", his entire body went on full alert. The mention of the mining company immediately allowed his thoughts to drift back to that point in time where the station had been sealed. He thought briefly of Scarlet, who had gone on seeking her quest for "karma" after the mission. He thought of his own personal wounds - his damaged pride for letting such a thing slip past him.
So it came as no surprise when Noboru immediately began checking his .45 service pistol, not saying anything but instead carefully inspecting the handgun, and shutting out the rest of the world.
