Junichiro shook his head, "Nope. I got it in a trade. Some soul eating Yokai ended up with one after eating some serial killer. She had no use for it so I made her a little something to help her hunger and she gave me the Sacred Gear. I'd actually been on the lookout for a Sword Birth or Blade Blacksmith for years by that time."
Rias looked confused, "Why would you want a common Sacred Gear like Sword Birth? That'd be similar to wanting a Twice Critical. Sure, it's something, but it's really not all that much."
Junichiro stopped what he was doing and looked at Rias. She blinked when she registered the look of sheer disappointment on his face, "Rias, darling, dear, little Rias, I am very disappointed in you for saying that."
He was a little excited over some of the readings he'd been getting so was slightly more excited and a little condescending at the same time, "While I admit Sword Birth doesn't have the sheer raw power of a Longinus such as Boosted Gear..." He gestured to said Sacred Gear where it was sitting on his bench, "It has something most Longinus lack, versatility and utility. With that common Sacred Gear I was able to match your entire peerage. Not to mention you've seen some of what I can do with the balance breaker."
He shook his head and went back to scanning himself, "If you maintain an attitude like that then don't be too shocked when someone with a 'lowly' Twice Critical kicks the crap out of you or when a Blade Blacksmith slices you to ribbons."
Rias actually took the time to process that and think on what Junichiro had said. She hated admitting it, but she knew he was right when he said he could take out her entire peerage by himself. He was officially the strongest member of her peerage, even stronger than herself. Not in raw power, but in what he was capable of doing. His... flexibility and the ability to counter them with his various creations.
"Right. I'll try and keep my bias down to a minimal amount."
She really didn't want to hear an 'I told you so' from Junichiro if she ever came across a lower tier Sacred Gear and lost because of underestimating her opponent. That would just be plain embarrassing. She didn't want to think about that anymore so she moved onto a different topic, "It will need to wait until next weekend, but we should celebrate you joining my peerage. The whole peerage, together."
Junichiro continued to scan himself with different wands and humming over the information he was being fed, "That sounds nice. Speaking of your peerage. Who do you want me to train next? Akeno, Koneko, yourself, or the Bishop I haven't met yet?"
Rias winced a little at the mention of Gasper. It wasn't that she was embarrassed by him, far from it, but Gasper was... difficult. She sighed and shook her head, "It'd probably be best if you waited for a while before I introduced you to Gasper-kun. He's skittish and afraid of the world." She looked down with flushed cheeks as she admitted her shame, "I'm not strong enough to help him control his power. Anytime he gets surprised, upset, scared, or anything else, his Sacred Gear Forbidden Balor View will activate and freeze time."
She let out a soft sigh, "It terrifies him every time it happens which just makes things worse. He's become a complete shut in and won't leave his room, not that he's allowed to because I was forced to seal the room."
Junichiro stopped scanning himself and studied Rias for a bit, "That really bothers you, doesn't it?"
Rias nodded, "Gasper-kun was dying so I used my Bishop piece to save his life. He's grateful, but he's also really scared of the outside world due to his circumstances. Because of my own weakness I can't help him so the only thing we could do was seal him away until I am strong enough to help him control his powers."
Junichiro wasn't sure how that actually worked so there was nothing he could do to argue against the actions Rias had taken. Instead he accepted it and offered, "Well then, I guess I'll train you next. I've heard a lot about the special power of the Bael clan and how it was passed down into the Gremory line. I'm very curious about the Power of Destruction. I can't wait to see it in action and think of ways to help you develop it."
That was partially a lie. He already had some plans to help her develop it. As far as he could remember, all she ever did with it was summon up huge amounts and fire them off in the hopes that the big attack would quickly end the fight in her favor. The problem was, the attacks were large and slow, easy to dodge and a complete waste of power. Power she didn't really have to spare.
His thought process was to go in the opposite direction. Instead of big balls of death, she should be firing Freeza-style Death Beams that moved at extreme speeds. If she could tag her target and slow them down, then she could easily land a bigger blow. Or, if she got really good at the small precision shots, she could take out her enemies with a single well placed shot using a minimal amount of power. Efficiency at its finest!
Of course, he also wanted to train her after he'd used his Essence of the Blank. If he understood it correctly, then it was possible for him to learn the Power of Destruction for himself. If he could do that, then he could learn any of the clan powers that the devils coveted so much. There were some really excellent ones as well. Things like time control, canceling others abilities by understanding them, even turning into freaking dragons!
