To make his point he lifted his current arm, which easily looked like it came off of a suit of extravagant plate mail armor.
Seeing as how that was the easiest thing for him to design, it made perfect sense to appear like that. Aside from that, he hadn't had the proper materials to make doppelganger flesh to cover it up at the time. Finding replacement materials had taken him quite a while.
"Well, there's no time like the present."
So saying, Junichiro reached up to his right arm and rolled up the sleeve on his tee-shirt. It was a matter of moments for him to detach his current arm and attach his new one.
After the first he'd had some minor surgery to install a simple quick-change port in his stump. Once he stopped growing he had plans to make all kinds of different arms for different uses and situations. Like one that did nothing but throw rocket punches! Yes, he was still determined to have such an arm! But he could also design arms for more precise movements to help with working on smaller things.
He planned to get into electronics to see if he could incorporate technology and magic together and bring Magitek into existence. He'd looked but no one seemed to be doing any research on the subject.
Soooo maybe a steampunk arm at some point just for the cool factor? Eh whatever.
As he attached the new arm there was a hiss and click as the socket connected properly. He felt a slight pinch and groaned in minor pain as the arm fully connected and nerves he hadn't felt in a year sprang to life.
He felt a tingle, like a sleeping limb waking up after being sat of for a long time. The pair of them watched as the doppelganger flesh slowly transformed to match Junichiro's natural skin tone. The only sign of there being something off about the arm being a crease and line where the prosthetic connected to his flesh.
As the tingling sensation faded and the numbness lifted, Junichiro started to feel other sensations from the new 'flesh' on his arm. First came warmth as he wasn't too far from the coal forge. It wasn't going full blast but he had some coals banked so it was emitting at least some warmth.
It was enough for his new, still sensitive, synthetic skin to pick up. After that he could feel a slight breeze blowing across his skin cooling it as air naturally moved through the area. The sensations were almost overwhelming to him as he hadn't felt anything from his missing limb in so long.
Taking a deep breath to calm his roiling emotions, he lifted his right arm and marveled at the feeling of it moving. It definitely did not feel like his left arm but it was feeling none-the-less! For a few quiet minutes he lifted, bent, moved, and flexed his arm and fingers to get a feel for their range.
It still wasn't as good as a natural hand and arm, missing some of that freedom of movement being made of more rigid materials all through it. Still, it was a thousand times better than his first wooden arm and a definite improvement over the third version he'd just removed.
He was brought out of his reverie by Azazel letting out a soft whistle, "That's mighty impressive, kid. If I didn't know any better, I'd think that was your natural arm."
Azazel's praise was honest. In the last year he'd kept as close of an eye on Junichiro as he could. To say Junichiro's growth was impressive would be an understatement. The only person he'd seen grow stronger faster was Vali. Given Vali's determination and goals though, it was no surprise that he was growing in leaps and bounds.
That's just how it went with any Sacred Gear holder, let alone one with a Longinus class one. He honestly couldn't wait to see Junichiro's growth after he got his own Sacred Gear. Even with a weak one like Sword Birth, it should be a sight to see.
The two spent a little time chatting while Junichiro got used to his new arm. Once he felt comfortable with it, the two of them left the workshop. As they were walking, Azazel grew a cocky smirk as he innocently asked, "So, when are you planning to ask Mittelt out on a date?"
Junichiro was instantly blushing and almost tripped over nothing in his surprise. He and Mittelt had actually become rather good friends over the last year.
Spending every day together ensured they would either grow to like or hate each other. Despite their different interests, they actually got along pretty good.
They both shared a love of cooking and had small competitions to see who could cook what better. Mittelt often won due to sheer experience, but it was fun regardless. Mittelt also had an interest in fashion, something he could relate to since his Artificing abilities covered making clothing and leather armor. She was one hell of a clothing designer and had mad skills with a sewing machine.
All of her clothing was hand made and looked as good, if not better, than the stuff in stores. She mostly stuck to her signature Gothic Lolita style, but it was also nice to see her making normal dresses, skirts, and other clothing then trying them out. With his puberty in full swing and his hormones going crazy, he'd ended up finding himself attracted to the petite fallen angel that was hundreds of times his own age.
After recovering from his near trip, he glared at Azazel, though there wasn't really much heat behind it. Especially not with his cheeks still tinted red. Azazel just looked at him with a raised eyebrow, clearly waiting for a response. Junichiro finally looked away and sighed, "I'm not sure. I've been wanting to for a while now."
Azazel just gave a nonchalant shrug, "Just ask her. The worst she can do is say no."
