["..."] Talking through the Sacred Gear

['...'] Talking in the Host mind

[...] Sacred Gear Actions and modes

When Issei turned around he tensed up as his blood started to run cold.

There they were, his ex-peerage who he shared so much with. The girls who once mesmerized him and held such a prominent place in his heart, the guys who he considered to be good friends but no longer they were those things. Now they were all people who took part in finally breaking the brunette's heart completely.

Issei wanted to be mad at them, to lash out at them, but the feelings of sorrow and anguish overtook the rage in his heart that was boiling with each passing second.

He averted his gaze to the ground; Not being able to look at the faces of the people who caused him all this pain while struggling to keep the unshed tears at bay; Making him start shaking slightly.

Vali and the rest of the team looked at their pained teammate in pity and sympathy as they knew very well the amount of pain that the people who stood in front of them caused him.

"I-Ise...Why are you with them? They are a part of the Khaos Brigade," Rias said in a hollow voice as she and the rest of her peerage kept looking at Issei and his team with wide eyes.

Issei flinched upon hearing the question but chose not to answer the redhead's question; Keeping his focused stare on the source of all his pain as his mind was overcome with the feelings of anguish.

'Why did she reincarnate me? She should have left me to die instead of causing me more pain,' Issei asked himself in sadness as he thought about the fateful night when he was given a second chance by Rias after his death by the hands of his first girlfriend; No longer seeing it as a good thing. Instead, he saw it as nothing more than a curse meant to cause him nothing but pain.

['Partner stop this!'] Ddraig roared in fury within his partner's subconscious after hearing the brunette's thoughts; Making Issei winch from the power behind his partner's roar.

Ddraig for his part was seething right now. At first, the Dragon loved the Gremory peerage as he thought that they would be good for Issei, and he was confident that they would be able to mend his heart and vanquish his fears after Raynare, but he was gravely mistaken as those who were supposed to be the glue for his heart ended up being nothing but a hammer that broke the remaining pieces into nothing but mere shards.

The Dragon, of course, was not really surprised as he already knew the vicious nature of the Devils due to some of his past possessors being Devil's themselves or associating with them but that didn't mean that Issei deserved it. Unlike the previous wielders of the Boosted Gear, Issei was considered to be the best wielder to date by Ddraig and he cared for the brunette a lot despite the torment he was being put through thanks to his wielder's perversion which to his luck was no more.

Fearing that his partner's despair would worsen even to a point of no return Ddraig wished to prevent it so he chose to do something that he wasn't sure he would be proud of. He released all his rage and killing intent into his partner so the latter as an attempt to snap him out of his despair and make him fueled by the anger he was supposed to feel towards the Gremory peerage.

Issei was still deep in his state of depression when all of the sudden he felt like his soul was consumed with intense rage and killing intent that were aimed at none other than Rias peerage who looked at him with their jaws dropped in response to the emotion spike that occurred within him. Issei gasped in shock at the sudden change before he noticed that his Boosted Gear appeared on his hand while he was still in his stupor but before he could react to it he was enveloped in a golden light.

[Welsh Dragon Balance Breaker!] Ddraig's voice boomed through the Boosted Gear sounding angrier than usual; Making the Gremory's peerage to cringe.

Issei for his part was more than shocked when he found himself clad in his scale mail. He had no idea where those intense rage and killing intent coming from but after spending a minute to think about it Issei realized that it was Ddraig who flooded him with his own feelings; Making the Boosted Gear to respond to his feelings and force him into Balance Breaker.

When he gazed at his ex-peerage again, he could feel that something was definitely different from how things were just mere minutes ago. Sorrow and anguish were replaced by boiling rage and intent to kill aimed at the peerage who now had looks of utter horror from the sight of Issei in scale mail looking ready to kill them.

Seeing Issei like this made them shiver as this was not the brunette who they grew to love. No, this was the result of the now broken brunette who they along with Raynare helped to create.

Issei's team stared at him in awe after they sensed the spike of rage and killing intent before he was suddenly clad in his scale mail. All of them having the same thoughts in their minds.

'We need to back off and let him do his own'

Rias who was the first to recover from the shock they were all feeling knew that her peerage was in danger so in response to the will to protect her peerage along with the swirling emotions that she felt after seeing Issei her Power of Destruction flared up and enveloped Rias who was now releasing an impressive aura on her own; Making the rest of the peerage recover from their shock to and prepare for the imminent battle despite how much they didn't want to fight Issei.

"Ise, please! We don't want to fight you so, please stand down," Rias said with hope clearly evident in her voice; Hoping that the brunette still had feelings for them other than hate and anger.

Much to Rias and her peerage dismay Issei did not respond and instead stood still for a few seconds before he suddenly vanished; Making them to panic and look frantically around them.

Xenovia who was stationed near Irina at the back suddenly saw Issei appear behind the letters back ready to deliver a lethal kick to her back. Xenovia who knew that one of her best friends were about to be severely hurt did the only thing she could and rushed to block Issei's attack with her Durandal.

The rest of the peerage gasped when they heard the sound of metal clinking with each other and quickly turned around to find the source only to find Xenovia struggling to block a kick from Issei with her Durandal.

"Xenovia!" They all shouted in worry and were about to rush to the bluenette's side to help her with blocking Issei's attack when Koneko who was the closest delivered a fist to the defenseless Issei; Sending him flying across the street and into a nearby building.

"Xenovia! Irina! Are you ok?" Rias asked in worry as she reached them to which she was answered by a set of two reassuring smiles and nods from the girls; Making her exhale a breath in relief.

They all turned their gazes when they heard the sound of rubble being moved before Issei came out of it looking unscathed.

Quickly they all charged their attacks and aimed them at Issei when all of a sudden he disappeared once again; Making their panic from before to return as they began looking for him once more.

They couldn't find him no matter how much they looked and they were about to stop looking and just wait for any sign of him when they heard something that sounded like energy being charged.

Before they could even react to the sound, they heard Issei yell something that made them shake.

[Dragon Shot!] He yelled as he directed the attack onto Koneko who took it heads on as she was unable to deflect it; Rendering the Rook unconscious and severely wounded.

"Koneko!" They all yelled in terror before Asia who rushed to her aid reassured them that she was alive but severely wounded; Making the blonde Bishop start healing her immediately.

"Why did you do it Issei-kun? Koneko was your friend!" Kiba asked in anger, but to his dismay, the brunette did not respond; Making the blonde Knight shake with fury before he rushed at the one who he once considered to be his best friend.

While Kiba and Issei were engaged in an intense melee battle, Rias and the rest took this chance to regain their thoughts and come up with a strategy so they won't end up being dead; Believing that Kiba will be capable of fending off Issei in the meantime.

While Rias and Akeno were supposedly stronger than Issei they knew that when a sacred gear host is fueled by intense emotions such as anger the sacred gear would correspond to its possessor feelings meaning that any advantage Rias and Akeno had over Issei in terms of power was no longer relevant as they didn't know the extent of the strength Issei could receive from his Longinus.

After they had come up with a strategy, they turned around and gasped at the sight they beheld.

Kiba who was on one knee was panting while holding his hand that like most of his body bled while Issei looked unaffected except for a few scratches on his scale mail; Meaning that Kiba managed to slightly damage the armor.

Much to their horror Issei approached Kiba and kicked him in his abdomen; Sending him flying backward into Rias and the other's direction.

Akeno who was the closest to Kiba checked him and informed them all that he was still breathing, but if he wouldn't get any medical treatment soon he won't make it; Making the remaining members of the peerage shake in fury from almost losing another precious friend.

Any feeling of doubt about fighting Issei disappeared from the all of them and they quickly charged their power again and started fighting the brunette who looked unfazed from the display of power.

Xenovia rushed to Issei with a loud battle cry in an attempt to land a decisive blow on his head with her Durandal, but to her dismay, Issei blocked it with his hands at the last seconds although she smirked when she saw that his hands were damaged in the process.

Her happiness did not live long when suddenly she felt like her stomach was torn open and was forced to exhale all her air; Making her snap her gaze down only to see Issei's knee striking her stomach with an intense force that sent her flying to a nearby tree.

Much to Issei surprise Xenovia stood back up although barely and rushed in his direction with a fierce battle cry once again, but to her dismay, Issei managed to grab her face and slam her into the ground; Generating a crater in the process.

The remaining members of the Gremory group who consisted of Rias, Akeno, Irina, and Asia paled from the losses of their friends.

They started to shake once again only this time it was from fear, fear of not being able to escape this fight alive.

With each loss, they received Rias Power of Destruction increased in strength although she wasn't sure her powers would even be useful against Issei but at this point, she had no choice but to believe that it did.

"Asia, how are everyone?" Rias asked her Bishop who looked like she was about to collapse from the strain of healing the downed members of the peerage.

"Th...They are fine for now Rias-onesama," Asia said in exhaustion.

"I see. Thank you, Asia," Rias replied with a grateful smiled aimed at her Bishop and one of closest friends who without her the downed members of the peerage would have been no more.

Rias glared at Issei halfheartedly when she averted her gaze from Asia to him.

"How could you Ise? Those were your friends who you almost killed. I thought you cared for us!" Rias said with tears now cascading down her cheeks.

Even after what he did Rias couldn't find it in herself to hate Issei because deep inside she hoped that the brunette would forgive them despite how little that hope was.

Right now, despite her unwillingness to fight Issei she had too. She had to make sure her peerage and dear friends would live to see another day, and she wasn't going to give up even when the person who she was fighting held a special place in her heart.

Rias widen her eyes when she saw Issei prepare yet another powerful attack aimed at her direction that unlike the last attack was much more powerful.

Seeing no other way she charged her Power of Destruction and shot a powerful beam at Issei at the same time he released his own attack.

[Dragon Shot!] He shouted with so much anguish and fury that made Rias slightly quiver while sadness filled her; Knowing that she and the rest were the cause of those feelings.

When both attacks collided with each other a bright light enveloped the entire area; Vali's team and the remaining members of the Gremory group to get blinded. Fear was filling them for their friend's fate as each attack battled for superiority.

When the light has faded Issei and Rias were both panting as they were both starting to be overtaken by magic exhaustion; None uttering a single word to each other as they slowly recovered from their fatigue.

Much to Rias luck the battle for superiority ended up in a tie at the last second, and she managed to escape physically unscathed but also substantially exhausted from the effort to fend off the attack that would have surely killed her.

"Rias!" Akeno shouted in worry as she rushed to help her best friend and king before she will collapse from exhaustion.

Much to their dismay, Issei managed to recover from his magical deprivement thanks to his Boosted Gear that kept boosting his powers; Being ready to continue fighting in no time much to their horror.

Akeno who saw Issei preparing to fight again quickly flew away while supporting Rias and landed near Asia; Hoping that the Bishop could help Rias to recover quickly.

After Akeno had asked Asia to help Rias with her exhaustion, she flew back to the remaining debris of the place where Issei and Rias attacks fought for superiority.

No longer seeing a point in trying to reach the brunette with talking Akeno instead reluctantly decided to attack Issei with as much power she could muster.

Clad in her priestess uniforms Akeno started preparing to attack Issei. She knew that attacking with all her powers focused on a single attack would be fruitless after what happened to Rias so instead, she decided that she'll try and exhaust Issei once again so she could strike him when he isn't able to defend himself so he'll go unconscious which would give them enough time to retreat.

Issei, still in his scale mail that was cracked in several places has already started showing signs of physical fatigue, but despite his fatigue, he refused to give up and so he quickly charged up and began to battle Akeno.

Issei and Akeno were clashing in the sky with speed that even a Devil couldn't catch sight on; Both fueled by the intense emotions they were feeling.

Akeno who kept attacking Issei with her Holy Lightning managed to strike the latter a few times; Making her hopeful.

Issei for his part managed to land only a single Dragon Shot on Akeno although the attack was weak it still did quite some damage.

They kept fighting for a long time, both sending powerful attacks towards each other; Both hoping that the other would be the first to give up.

While Akeno regained her breath after releasing yet another powerful Holy Lightning Issei looked down and saw that some of the peerage members who he's struck down have started to slightly recover after Asia healed them; Making Issei realize that it won't matter if he will defeat Akeno as long as Asia still standing and healing them all.

Deciding to take advantage of the small break he received to turn the battle in his favor Issei quickly dived down before Akeno finished regaining her breath; Making the latter to gasp in horror as she saw the direction he was heading at.

"Asia!" She yelled from the bottom of her lungs in an attempt to warn the blonde but to no avail, as she was too far from her so instead she quickly dove down after Issei as fast as she could with one purpose in mind. Stopping Issei before it's too late.

Asia who was focused on healing her fallen friends gasped in surprise when she heard something stopping in front of her.

Looking up to see what it was she widened her eyes when she saw it was Issei who was standing in front of her.

"Issei-san," Asia shyly said as she began crying, but much to the girl's horror Issei ignored her and instead retracted his hand as he prepared to deliver a lethal fist aimed at her.

"Issei-san, please don't do it," Asia pleaded in hope as she was now sobbing uncontrollably but to her dismay, Issei showed no signs of stopping so instead she prepared for the upcoming killing blow while believing that if it was God's will, then she will accept it.

Asia! Get away fast!" She heard Akeno say from afar, but she kept still.

Irina along with Asia and Akeno was the last standing member of the Gremory group who stood away from Asia snapped her gaze to the blonde's direction and gasped in shock as dread filled her; Not being able to mutter a word as she was overtaken by the shock of the sight she beheld.

Asia flashed Issei one last smile before she closed her eyes and waited for his attack that would end her life.

"I'm sorry for everything Issei-san, Goodbye and thank you for being my first friend," She apologized in a whisper before she felt his fist coming closer and closer to her face.

Asia no!" Akeno and Irina shouted in anguish as they witnessed their beloved friend's death; Both too late in helping Asia.

Tears started to cascade down their faces as they felt a piece of their heartbreak, but the thing that happened then made them gasp in awe and disbelief.

There stood Issei with his fist just mere inches from Asia's face.

"I...I can't do it," Issei spoke in agony for the first time since the battle begun.

"Issei-san. Thank you," Asia tenderly thanked as she slowly opened her eyes.

But before Issei could do or say anything he was quickly struck by lightning; Sending him flying into a nearby building.

Akeno who launched this attack quickly grabbed Irina's hand and dragged her with her near the others before she prepared a magic circle that would teleport them away.

AN: OK now I guess a lot of you are greatly confused as to why Issei stopped his attack midway and said he couldn't do it and that will be explained in a future chapter,

Ok, that's it for today. Don't forget to Follow, Favorite, and Review! :) I'll see you next chapter!
