He turned and looked at the wings made of swords behind himself, "And, naturally, all of the swords have various effects and abilities for me to bring to bear." His helmet turned to face Rias, "They can also..."
When he stopped talking several of the swords flipped around in the air, their tips going from pointing at the ground to aiming in front of him. With a flick of his wrist the blades launched through the air like missiles. A red one ignited in flames, a green one fanned those flames by adding wind to them, and the third one shattered into dozens of pieces that all passed through the flames and caught on fire. The shards and both blades slammed into the ground far away and caused a small explosion. He didn't put a ton of power into it since he didn't want to completely destroy his own back yard.
Moments after the three blades exploded, the air behind Junichiro rippled as the three blades reformed. As long as he maintained the Balance Breaker all of his swords would automatically reform, part of the 'Infinite Arms' in its name.
Rias watched the entire thing with a bit of awe on her face. While the explosion wasn't all that impressive, she'd seen much more devastating ones, she knew that with more power it would become quite a bit more dangerous. She shook off her stupor and smiled brightly at Junichiro, "Now I really need you in my peerage."
Junichiro dismissed his balance breaker, the swords, armor, and shield slowly fading away as glimmers of light, "Just give me some more time to get to know you all a bit better. Like I said before, so far I'm leaning toward joining."
Rias nodded in understanding but he could clearly see the excitement, desire, and greed she had toward him in her eyes. It was very clear to him that she would do just about anything to get him to join her peerage. If she knew this was only one configuration of his Balance Breaker she'd probably kidnap him right then. It wouldn't be infinite arms if it was such a static thing, would it?
He probably shouldn't let her know how good he was at cooking either. She'd definitely kidnap him at that point.
Junichiro closed the door to his teleportation receiving room as the glow of Rias teleporting out faded. They'd spent a little longer talking but Rias had been too overwhelmed by his revelations to really think of any more questions to ask him. He was sure more would come after she finished processing what she'd learned. Until then though, he had work to do!
He opened the door to his workshop and made his way directly to the Boosted Gear gauntlet sitting on his workbench. Due to being in its non-awoken Twice Critical state, it was a rather dull red with a green gem on the back of the hand and dull golden spikes on the sides of the wrist. It didn't even cover the fingers, leaving them bare and making the gauntlet look even smaller.
He shook his head at the pitiful look of the item as he knew how bad ass it could grow to look and the sheer power it contained. It was extremely tempting for him to simply fuse it with his soul right then and there. It could instantly help him with so many of his projects. He knew it had amazing combat potential, and fully intended to use it for such, but his true desire for it was to help him with his work. Being able to double his magical power, even just a single time, would be an amazing boon to his work. Doing it a half dozen times and compounding it? He had to fight not to drool over the possibilities.
He quickly shook his head to clear it of distracting thoughts. As much as he wanted to use it right this moment, he wouldn't. He even had a couple of reasons rather than just not using it so Rias could reincarnate him.
The biggest was...
He walked over to his wall of wands and started pulling several down. Each wand selected was a member of his diagnostics selection. He wanted to scan every micron of the Boosted Gear and know it intimately down to the last detail. He especially wanted to see if there was any differences in the 'faith' systems that the Sacred Gears used.
The 'faith' system within his Sword Birth wasn't very robust or restricted. He suspected that the same could be said for many of the other 'low tier' Sacred Gears. He believed the 'loose' system within them gave them far more branching paths for evolution into various sub-species. He was pretty certain his own Sword Birth had become a subspecies due to his Balance Breaker. It wasn't just shields and armor he could create, but basically any weapon and armor he could imagine. That's why it was 'arms' and not 'swords' and 'forge god' and not 'sword master' or something similar.
His hypothesis was that stronger Sacred Gears would have 'tighter' faith systems that drastically limited the options for evolution. It obviously wasn't impossible for a strong Sacred Gear to become a sub-species, but it was very rare. He could only remember one off the top of his head, Sephiroth Graal.
Speaking of, he needed to remember to find Valarie Tepes and kidnap her at some point. Her Sacred Gear was just too powerful to leave in the hands of the vampires where it could be exploited by undesirables in the Old Satan Faction, like that Rizzle... er... Vali's gramps. He couldn't recall the exact details but he did remember 'infinite numbers of red dragon emperors' being related to it somehow.
He might be wrong. It didn't matter. Just that possibility was terrifying enough to snag Valerie and it to hide both away.
He dismissed that as something to do later. He refocused and waved the first wand over the Boosted Gear. The tip of the wand and the gauntlet both glowed the same orange color as information began to coalesce within his mind.
"Hmmmm that's kinda... sick but makes sense I guess. Using some of Ddraig's body to make the gauntlet his soul was stored within. It'd definitely have the highest possible compatibility. Hmmmm just a portion of his body though. Definitely not enough to produce scales for something the size of Juggernaut Drive. Only enough for the Scale Mail, huh? Probably got something similar to the conjuration system of Sword Birth."
