"So what is the max you can use that won't hinder you much?" Rias asks.
"About 10 is optimal but 15 is the max that I can endure with a short break after it." He replied.
Nodding to that Rias pointed to the rock which was repaired and looked like it was made even stronger.
"I do have a new attack that I want to try, so this would be a good place to do it." He spoke to them as the Booster Gear appeared and started to give it signature BOOST.
After a minute or so, Issei feeling that it was about enough boost's he called Explosion and lifted his left arm in the direction of the rock.
Concentrating on the attack a small sphere formed in front of the gear as it shined in red light. Issei pulled back his armored arm and then hit the sphere of red light as strong as he could calling the name of the attack.
DRAGON SHOT
When his armored hand hit the orbit, it released an intimidating laser beam attack that completely destroyed the rock and went trow to make a trench all the way toward's the top of the mountain where it exploded in a massive explosion that made a small earthquake.
That attack blew everyone's mind's, if anyone took that attack head on, it would leave the devastating result to almost anyone in a range from Low-Class all the way to weak High-Class.
"That was an excellent performance Issei, we will work on your hand to hand combat, swordplay, and speed, also endurance for you to have a chance to endure your current max boost and for it to increase.
Magic is also important so we will work on that latter during the training. Raynare we will also increase your magic and combat skills.
Your magic is acceptable but you physical strength is lacking severely." Their King informed the duo as the nodded in acknowledgment.
"Good now I think that we could all go and relax for tonight before starting in the morning."
Whit that said Rias entered the house that would be their home for next 10 days with all of her servants following her.
In the next few days Issei and Raynare where beaten to shit by the members of the peerage, Akeno almost regualry left Raynare for death and Ise was brutally beaten by Koneko and embarrassed by Kiba's speed and sword skill.
Off course, those punishments in Raynare's and Issei's mind did help in their stamina and they did learn some technics and how to handle some situations.
But during his magic training with Akeno when he was at relative ease since she didn't focus on hand to hand or sword Issei found that something was pulling him toward's Norse and Slavic Magic more than toward Devil magic, as his reserves of magic slowly build up.
He could almost feel another presence in him,though when he asked Ddraig about it all he goten for the answer was that one of his predesesor was slowly awaking and that is why he new about thoes magics but couldn't used them until the person that was awakening has full awaken.
But as much as he tried he couldn't use even the simplest of spells that Akeno taught him which frustrated him a lot.
Thought after almost a week into their training it was finally time for Issei and Raynare to duke it out so the other's could see how much they improved.
After their match, it was Koneko's and Kiba's turn and last was King vs Queen.
"Okay you two, It's time to see how much you improved, so go full force. Against Phoenix and his peerage, you will need to outpowered or outsmarted them to win.
So when the two of you are ready to begin. Also Ise you can promote if you want." Said Rias as she stood with others to the sideline giving the two combinations enough space to fight.
"Well, it's time to show you weakling who is the superior here," Raynare spoke in her overly arrogant tone that started to piss off Issei.
"Yeah, yeah you wish little crow. If you have forgotten I was the one that beat the crap out of you when we fought last time."
He answered in a confident voice as he thought about what piece to promote to. Afte a few seconds, he decided and activated his Sacred Gear that immediately started boosting him.
"Promotion Knight," Ise said making the heiress think as to why he chose that piece when Queen or a Rock would give him overwhelmed power that would easily defeat the bishop.
When the fight started it was made clear to her why he chose Knight instead of a Rock or Queen.
When the Pawn pieces turned to Knight Issei exploded like a rocket toward's Raynare who had barely enough time to get away from a devastating blow that Ise sent at her.
In retaliation, Raynare summoned two spears of light and threw it at him who used his booster gear to blocked them as he made his way towards her with incredible speed.
Seeing that her attempt to pierce him was a futile she just formed her spear's and went into head-on on charge.
As Issei tried once again to hit her with his armored hand she used one of her spears to block which proved to be a wrong move as his fist smacked her spear like it was nothing and embedded deep in her stomach sending her flying.
As she recovered her barring she was immediately forced to move as another punch went toward's her this time to the head as she dodged it.
She could feel the raw power from the punch as the tree that was behind her was hit with the shockwave, that destroyed it in an instant and anything in a 15-meter radius suffered damage from it.
And that made her shiver in fear at the thought of what would have happened if that attack went throw.
Shaking her head she made fifteen spears and send them towards Issei as he tried to evade them but was hit with a few that left him slightly injured.
