Chapter 56 - Crom Gruach vs Issei Hyoudou

Two opposing dragons are the peak of battle as it pinned the two apex predators in the world. Issei stood unfazed from the decimated land from a mere punch. It was punch capable of destroying mountain range couldn't leave a scratch on him.

Crom Gruach stood up intently looking at Issei despite the distance he was instantly close the gap grabbed Issei's face then slammed into the ground causing a massive earthquake that cracks the sub-dimension.

Suddenly his instinct kicks in turn before being kick by Issei sending him flying then reappeared prepared another attack and Crom Gruach tolm the split second to redirect then spun around colliding his fist into Issei's skull.

However, Crom Gruach was shocked to see Issei was holding his fist with no damage looking with an emotionless gaze. He felt his desire for battle scream finally finding someone strong to quench his thirst.

"I didn't expect for you to be this strong. Hey you hadn't told your name."

"My name is Issei Hyoudou or Ise if you prefer."

"Issei huh? Sound familiar?? Hmmm well whatever lets resume!"

Both of them hover in the air while Crom Gruach prepare for another powerful punch Issei let go of his opponent's other arm and ready himself to do a punch. Their fist gathered dangerous aura with Crom Gruach black miasma and Issei with a Dark and red miasma. For a split second everything stopped then the instant their first collided.

BOOOOMMM!!

The sheer force had obliterated three hundred-kilometer radius of land from the impact. However, it was only the beginning as the two rage on doing an onslaught of punch and kicks causing the sub dimension to artificially create a thunder storm.

"Lets see if you can survive this!"

Crom Gruach took a distances always as his reveal being wounded by Issei instantly regenerate from his absurd power. However, his opponent is much more monstrous. Issei stood unharmed with his long crimson coat trailing with the wind. He wore inside dark shirt and carbon pants with combat boots.

It was clothes that he had usually used in the past and after being mostly fused with his past self had gained his tendency. Though he just liked how badass it looked.

Issei motionless at Crom Gruach who used his dragon Aura to create powerful projectile blasting them all to him. He returns the gesture by summons multitude of [Destruction Needle] then leap to attack Crom Gruach who evaded a planned strike.

Crom Gruach quickly blasts point-blank dark flames bursting into mountain size fire capable of melting anything.

"I didn't anticipate to put some 'effort. Well, it's expected since I had my seal."

The flames dispersed from a simple swipe of his revealing Issei's severely damage being incinerator by the flames that instantly healed by his Phenex Immortality. He had place seal inside him in order to keep getting stronger that once he remove his seal then his capable of defeating the outer gods.

This meant that he is a lot weaker than he should. Issei did this to ensure his precision in controlling his power more efficiently.

Crom Gruach felt the danger quickly getting a distance away but he was shocked to see his arm being severed cleanly. He saw Issei holding his hand casually looking at it.

"Here have this back and let's continue."

"Nah keep it. I didn't see anything from our meeting but it seem that I need to get serious."

"Oh I see well I'll do the same."

Crom Gruach increase his power by a hundred times as before while Issei summoned his Boosted gear then quickly transform not in Crimson Cardinal but rather his Diabolos Dragon God mode.

Their sheer power had create a massive crack in the fabric of Space as the two of them glances at one another observing their adversary.

"Now I understand why you seem familiar. You have the flesh of Great Red, the power of Ophis and the sacred gear of my Big sister, Irene."

Issei smiled since Irene had viewed him as her Little brother at the time when he met her and Albion fighting. The two had train him at the time before he and the heavenly dragon being sealed while the latter was unsealed.

Crom Gruach interest even more knowing that his Big sister host is his opponent. He desire to win burn even more than before increasing his power even further regrown his severed arm then spreading his pitch-black wings.

"Let's see what you can do. It's been a while since I fought a Boosted gear user."

"Hope you can handle my strength."

Crom Gruach crouch down as Issei appeared barely missing his fist by small margin. He spun doing a reverse kick on Issei face slamming him into he ground but it was block by his hand then used his fist breaking Crom Gruach legs causing him to back down.

He flew into the sky healing his injury as Issei infinity blaster charging then shot the beam towards Crom Gruach who took it head-on causing it to split.

The blast had caused the surrounding land into barren wasteland from the sheer force alone. The blaster died down as Crom Gruach remain flying despite his heavy wounded body.

"Hahaha, I never felt alive! You are far the strongest Red dragon emperor I have seen. This makes me go all out!"

Issei felt something and saw Crom Gruach pierce through his scale mail leaving a whole on his chest. He quickly removes his arm then did a barrage of punch that was too fast for Issei to keep up.

Crom Gruach's brutality attack issei not even give any time for him to recover. He repeated his action of endless attack cracking his opponent scale mail.

"Don't tell me this is all you got!? Come one I can see your bullshit from earlier!!"

His opponent suddenly moved colliding his fist with Crom Gruachand cancelling the force. Issei was just a bit stunned that Crom Gruach kept surprising him. Both of them remove their first and stood silently then punch their faces resulted in a cross dead lock.

BOOM BOOM BOOM BOOM!

Their fist were equally much canceling each other even with Crom Gruach, Dragon Aura bullet was easily countered by destruction bullets. They kept their onslaught on each other for a whole half hour with neither gaining an upper hand.

However, Crom Gruach was far more exhausted than Issei but still their power was equally match.

"Haaa…This…is..Amazing….though it's disappointing you held back…."

Crom Gruach's body slowly falls .d before it hit the ground Issei held him. He respected him due being able to withstand his power and did damage despite Issei's ability. He did sustain damages and wounds from him that were fatal if not for his immortality. If his younger past self fought him then he'd lose without a doubt.

Still Issei had countless advantages such his sacred gear [Ayin] and his tier magic that could easily assist him in battle.

"He did amazing facing you, Darling."

"Even in sealed state it's surprising his capable of lasting this long."

"Aniki, I saw you battle and gotta say I'm glad to see used that form again!"

Issei levitated the unconscious Crom Gruach and turn to the owner of the voices. They were Irene, Albion and Great Red who had spectate their battle when Irene had senses Crom Gruach.

Both her and Albion proudly watch Crom Gruach fare with their Husband who's capable of fighting them both. It was no easy feat to wound him even if Issei is sealed due to his battle experience.

They were proud that their little brother was able to survive his battle. Meanwhile, Great Red only watches because he was interested in Issei using her power after so long.

Issei remove his scale return back into his regular clothes. He glances to Crom Gruach expecting him to grow even stronger and help him protect his lovers. He touch his head then restore his memory since it was the perfect time.

"So are you planning on revive the two?"(Irene)

"Yes, they would prove useful to me as subordinate, and making them my slave will lower the chances of the enemy having powerful allies besides the dark apostle."

"Well just you know that the automata had spotted Irina and Xenovia in the area will likely visit you."

"I see, I'll leave it to you Crom Gruach, me."

Issei creates the clone to send the unconscious dragon to the guest room while Irene and Albion went with the clone and Great red went to watch some sports.

"Now then lets summon some subordinate!"
