A few minutes ago.
Right after they had strolled passed the roundabout, a question sudden popped into Ciel head, prompting her to ask Envy to quench her curiosity.
"Master that aura that you used when facing the gaints was that... Weopons aura."
"Yes." Envy paler than before responded.
Hunter with mystic weapons could fight on even ground with devil and Angels but unlike this races humans were not born with inhuman phyqsuie and whiles those provided by a mystic were no slouch, it could not compare to the physique of a devil hence weapons commonly dubbed mystic aura was something humans and Angels invented to compensate for that weakness.
Every mystic left of a form of aura and by harnessing that aura from the mystic and coating themselves with it they where able to strengthen their body to further height and coupled with the already potent physical stats of a mystic user they managed to overcome the weakness of losing to devils in a contest for strength but that brought about another problem.
Devil could also used it,futher widing the gap but unlike humans who had a completely immunity to divinity devil had no resistance so using mystic aura indirectly hurts them.
'Back when I had my mystic it was my goal too in fighting and I undoubtedly called a genius in using it..I don't want to brag or anything but I've have you known you're standing in the presence of the sword aura god."
"Okay...."
A bit threw of by his bragging she glance at the sword in her right left arm and and spoke.
"Race wasn't the only things we switched."
"Yeah I lost my concept to you and I gained you mystic." Glancing the the new mystic rune in his hands he sigh but nothing the complicated and sorry expression Ciel was showing him gently patted her shoulder and decided to give her a little encouragement.
"The lost isn't that severe, I can still feel a faint presence of my concept within myself and ones I can full comprehend it again every will return to normal."
"But until then you be weak."
"Hey at least I have you miracles." He chuckled his eyes sparkling with excitement.
Gaining her mystic give him an insight about how her abilities work and honestly it was so busted he couldn't help but wonder how far he could take it.
"But you respobilties..."
"Oh!"
Finally understanding why she was sad his expression darked.
He, currently wasn't Envy that position was now held by Ciel meaning everything going forward, his responsibility, his position everything will have to be handled by the poor girl.
"I'll help don't worry.", he assured.
It wasn't just out of pity he said that but because he knew she would messed it up without guidance.
Her expression brighted up as she heard his words.
"Ok can you start by teaching me mystic aura."
Normally two different people couldn't use the same mystic but for some reason Ciel could used her mystic even while he currently had the position as its owner.
She probably wouldn't be able to use the miracles again but he had a nagging feeling she might be able to use mystic aura.
"Hand me the sword then."
So he decided to teach her after all she was going to need during the fights ahead.
------------
"Remember do not used it in continuous sequence otherwise you end up killing yourself!"
Recalling the warning Envy had given her before he passing the knowledge of mystic aura to her, she began enveloping the silver aura around her sword through her arms, veins and bones.
Familiarizing herself with the feeling she quickly cutted of her connection and began to ran forward.
"As a devil always released the aura moment before the attack connect."
Meeting her advance, one of the figure a human made of stone, manifest a stone spear within its arms and thrusted it foward but she swiftly manveared her away under the strike and delivered one of her one.
Her sword traced her silver light through the air and just as it connected with the body of the stone human, its shine intensified and ruthless slashed the stone human in two.
As its crumbled into nothingness another lunged towards her from behind this time she swifty spuned her body around and delivered a roundhouse kick straight into its jaw.
It's shattered upon impact as a third one followed which she quickly dispatched by delivered an axe kicked down with her raised leg.
Then another and another....another....
She met sword strikes with hers, she evaded the thrusted of the spears and clubs, she shattered and deflected the arrows and javelins.
Three kills become four, then five.....then ten....then twenty.
Her body began to heat up, her heart began to pound within her chest, her gaze sharpered and narrowed.
Ducking underneath the thrusted of five spear from all sides, she quickly sweeped her attackers of their feets and with the force she carried they shattered and crumbled apart.
Not wasting any time, she got on her feets and rushed towards the dozens of stone humans approaching her.
The marched with violently intent with each of their stomps erupted a tremor through the streets.
As she neared them she leaped into the air, soaring pass the vanguard and dropping onto their body with the force of an hammer that shattered the stone human she landed on.
Surveying everything around her she slightly crounched and holding her sword in a quick draw stance and let out a deep breath.
Sharping her gaze to astronomically height, her vision grew red as the world seem to came to a stop.
With that she shifted her right foot foward and with a single fluid swing, her sword pulsed with a blinding light as a crescent shaped slash tore through everything infornt of her but she wasn't satisfied a she suddenly gripped her sword with both hands just as her swing was about to end she gracefully spuned around as the crescent formed into circular strike that destroyed everything within a 360° scope.
As the slash expanded and kill everything around her she fell on her knee and stabbed her sword into the ground.
"So...tired."
She panted relentless as her boys now drenched in sweat had mist coming out of it
"Conviction... conviction.... conviction...."
Repeatly chanting that world she rose up ones more this time her steps where weak and it seemly liked a single misstep will end with her on the ground but to her,right now such mistake couldn't be made so fueled by the determination to find Envy she gazed up the mist fuel sky as hundred more stone humans challenges her ones more.
