Kuhaku Shiro
Shiro's head and eyes followed after Gren as he took off through the roof, quite literally. "Ohhh...." he said in awe. Shielding his eyes with a gloved hand, he grinned widely. Laughing as he was more than mildly impressed by his friend's rather dramatic exit. That was Gren for you, go big or go home. As far as people he knew went, Gren was far from subtle in every aspect of his life. Shiro even softly clapped a few times, though his applause would go probably go unheard. Wherever Gren went, explosions typically followed.
"Witnessed."
Shiro said quietly, for some inexplicable reason.
Turning back to his work, messing with his Scroll, Shiro's perception alerted him to his cherished team leader approaching him from behind. His ears twitching and swiveling, he kept his back turned to her and focused himself rather easily. Tapping away at the screen of his Scroll's tablet function. He listened to what Sapphire had to say, but he gave her a short and curt reply.
"Okay. I'm sure we'll be fine without you."
And left it at that.
Once she left too, Shiro figured it was time for him to do the same. He would need to check out his weaponry and some Dust ammunition while he was at it. No telling what they would find down there in those mines. Like, giant armored centipede Grimm or something. Looking up at the CNC machine in front of him, he was sure that it would continue to work just fine without his oversight or guidance. He was sure no one would be so petty to steal what it was he was working on as well, so walking away from it he passed by Sangue.
Flashing her a smile and with a wave of his hand, he continued to stroll right past her.
Scroll in hand.
"I'm gonna go now, Sang. See you at the air docks! I'm sure this'll be fun!"
Then, exiting the Armory, not aware that he was leaving the very place he needed to stay at to check out his gear, Shiro traipsed along. Eyes glued to his Scroll, Shiro was victim to his own tunnel vision. Concentrating on every little detail and part of Sangue's feature arm that he still needed to work on. Deciding which would be best left up to Sangue's decisions and Gren's areas of expertise.
Muttering to himself, he stared down at the 3D rendering of Sangue's conceptualized arm.
"There needs to be connection points here, here, annnnd here! Something to feed the 'tendons' through to be controlled by a small motor or gearbox on the upper arm. These need to be segmented. Joints mimicking the human skeleton. Easy 'nuff! But...what about the armor and coverings? Hmm, might as well keep it simple...Although...what to secure the separate pieces together with? Some sort of latch or lock. It has to withstand the rigors of combat without failing and exposing the more delicate internals. That would be life-threatening and problematic to say the least..."
Walking further and further away from the Armory, he continued to talk to himself.
Head down and low.
Tapping and swiping away at his Tablet while he brainstormed...
