Chapter 52: A heart breaking farewell. Live on for the future!

Hello to all my amazing readers, both long time and newcomers. We are sadly approaching the end of this story, with only two chapters left to go. After this story is finished, I will be taking a break from writing High school DxD, and returning to my other projects. Then I will return with a third addition to this story. Making it a solid trilogy. Now please enjoy the next chapter.

Red, yes that is the colour that the sekiryutei sees before him. A tainted, twisted shade of red mixed with a heartless blackening liquid, dripping from the empty hole in the super devils chest.

The Sekiryutei's hands are stained with this revolting liquid, their stench lingering endlessly on him as if to proclaim...

This was not in fact the end of the nightmare. That the sekiryutei will end up spilling more blood in order for this war to be finalised.

Issei stared at the corpse of his vanquished foe. Its eyes wide open, and its body still remaining on its knees. His face curled up into a mischievous grin, as if he was readying himself to rise again. To plague Issei with one last fragment of despair, before he was ready to depart.

Issei's fists remained tightly clenched, his heart was beating at a rapid pace.

All was silent within the area, only the sound of the wind, and the exhale of Issei's breath could be heard.

A maniacal erupted laughter set Issei on edge, washing over him a wave of unease.

"You're a fool sekiryutei." the corpse uttered, its second coming becoming apparent and obviously painful.

Blood dripped down the super devils chin, much like the way a baby would during its meal times.

"What are you talking about?! Tell me now!" Issei said with his hand tightly clenched around Rizevim's neck.

"It's true, I admit that you have won this battle. I can feel my organs are beginning to fail, I'm just barely holding on.

But even though you may have won the battle... you have lost the war." Rizevim said which only resulted in Issei tightening his grip on the super devils oesophagus.

"Get to the point! It's not too late for me to make your death even more painful!" Issei said in an enraged state, having a bad feeling that there was in fact a level of truth in Rizevim's words.

"The forbidden beast, shall rise again. And you just unlocked the last seal." Rizevim said with a disturbing smile.

Issei let go of his enemy's throat from the shear shock and horror his anger had led to.

"No. That can't be true!" Issei yelled.

"Oh but it is! It was all your fault. You held the last chains heart in your hand, crushing it right in front of them. You've signed the death warrant for everyone that you love. This is all because you selfishly gave in to your anger and refused my plea of mercy. Trihexa is now free!" Rizevim declared feeling incredibly triumphant despite the pain and agony he was going through.

"What have I done?! The forbidden beast will destroy everything!" Issei said his actions heavily coming back to haunt him.

"Ha-ha! Your death is imminent Sekiryutei! Your weak and heroic self has finally been shown for what it truly is, a lie! The end of existence! What would mummy and daddy think of their noble son now?!" Rizevim mocked holding nothing back.

"SHUT UP!" Issei roared slamming him fist against Rizevim's skull.

Issei's inner ferocity and remaining power channelled into that punch, severing the super devils disastrously mocking grin from his broken and dead body.

The murdered super devils face, still mocking the sekiryutei with its joyful and malicious grin.

Issei breathed heavily, as he collapsed to his knees. His body suddenly feeling incredibly heavy.

"What's wrong with Issei?!" Akeno said her question quickly answered by the Hakuryuukou.

"It must be the after effect of his infinity drive. He's forcibly been grounded.

Before Akeno could reply to Vali's accurate explanation, the ground and the world that the devils inhabited, began to shake and tremor. Followed by a thunderous roar which coursed a chill through the spines of everyone there.

"What is that noise? My head hurts!" Asia cried out suddenly collapsing to her knees, her hands clasped to her ears.

"Damn it! Move! Why won't my legs move?!" Issei said as he inevitably struggled to stand up again.

"Such frightening magic power….. Is this even real?" Akeno said unable to comprehend the all-powerful petrifying energy signature.

"I've read about it in books, but I've never seen it before in person… TRIHEXA!" Issei yelled seeing this mind boggling creature appear in a huge magic circle.

"What should we do Rias?" Akeno said feeling like the frightened little girl she used to be.

"There is nothing we can do… Trihexa's only nature is destruction. It will destroy the underworld, the human world and even the heavens. I don't think we can do anything to stop it…" Rias said as she observed the frightening majesty of the forbidden beast.

"Oh god! Please save us!" Xenovia and Asia begged, knowing full well about this diabolic threat to humanity, the beast sealed by god himself. 666.

"I'm not giving up…. I will protect everyone!" Issei yelled trying to stand again.

Trihexa's appearance was a frightening illogical sight to behold.

666 has the appearance of a large beast 666 has the appearance of a large beast with characteristics coming from different animals a lion, a leopard, a bear, a dragon, etc. It has seven necks, seven heads, with ten horns, as well as seven long thick tails of different shapes. It also has four stout arms and two legs that are even thicker than its arms. Its main body is that of a primate leaning forward and is covered in black fur and what appears to be scales all over its body. There was no sense of unity. Its body had a variety of features from the different creatures, and it gave off a foreign sensation from its body. Its size is well over several hundred meters, making it significantly larger than even Great Red. With the numbers 666 on its seven heads, it was an overly powerful beast.

"Gooooooooooooooooooooooooooooooooonnn!"

It was just a roar, but it felt as though even their souls were being tightly clenched!

Rias and the other devil's had become awestruck, frozen in time. Visions of their deaths, racing through their minds.

"It's over…." Rias said completely defeated.

"Don't be afraid! It's not over yet!" Issei yelled making everyone come to their senses

"Issei?" Rias said suddenly out of her trance of despair.

"I don't care if it has infinite regenerating abilities, legs or no legs, I destroy it!" Issei roared still failing to stand up.

"Don't do it Issei-kun! It's too reckless!" Kiba warned but it was already too late.

"Let's do it Ddraig!" Issei yelled finally standing up again.

"Partner it's too dangerous!" Ddraig warned noticing Issei's diminishing life force if he went through with a full transformation again.

"I just need the chest piece! I just need the cannons!" Issei yelled ordering Ddraig to create a partial diablos dragon form.

By Issei's command, Ddraig gave his master the chest piece and the wing cannons needed for one final attack.

"Take this apocalypse beast! Infinity blaster!" Issei roared firing his most deadly blast attack.

A beam of crimson and obsidian launched from Issei's powerful cannons.

However, without the rest of the armour to support him, Issei fell to the ground head first, the impact giving him an immediate concussion.

Regardless of this self-inflicted injury, Issei's attack still hit its target dead on.

With his eyes barely open, and the dizziness overriding his system, Issei looked up at Trihexa, observing the battle damage of his all-powerful blaster.

To the Sekiryutei's delight and relief, the apocalypse beast had in fact lost one of its heads.

"Good, that's one down." Issei said the second his fragmented armour dematerialised, his body hitting the floor again.

All of a sudden, Issei's moment of success, shifted to one of despair and suffering.

Trihexa instantly regenerated itself.

"That's not possible…." Issei said, now unable to move his body any longer.

"Gooooooooooooooooooooooooooooooooonnn!" The mighty beast roared again.

"I can't move!" Issei yelled the beast now reverting its sights towards him.

"ISSEI!" They all yelled as the beast prepared to end the immobile Sekiryutei's life.

A flash of blinding crimson light blocked the ferocious beasts advance, shielding the Sekiryutei from imminent danger.

"Big brother!" Rias said noticing the swaying crimson hair draped over her beloved.

"Lord Sirzechs?" Issei said titling his head up towards his saviour.

"You did great Issei-kun. Now leave the rest to us." Sirzechs said gesturing to the other figures who had come to assist him.

"Us?" Issei said now looking over towards Sirzechs' reinforcements.

All members of Lucifer's peerage had assembled. Including Grayfia herself.

Along with Sirzechs Lucifer's peerage, some even more impressive beings had gathered to help take down the fearsome and ferocious beast.

Falbium Glasya-Labolas, was the Satan Asmodeus who was in charge of Military Affairs.

Along with this man, he was accompanied by various other mythological leaders, Serafall Leviathan, Odin, Arch-angel Michael, Azazel and Zeus himself.

"Quickly Sirzechs, we must implement the barrier before Trihexa has a chance to split its body up!" Arch-angel Michael ordered implementing his own magical power.

"Lord Sirzechs, what's happening?" Issei said unable to move nor comprehend the situation at hand.

"This is it. This is the final means of those of us in the top brass. According to our calculations, defeating Trihexa will require an enormous amount of time. Of course, being able to completely seal it would be best, but…it is unfortunate that that will also take a lot of time and is not the conclusion that we need." Sirzechs explained causing Issei to become distressed.

"What are you saying?" Issei said not really wanting to hear the answer.

"Regardless of whether we defeat it or seal it, either method is extremely time-consuming. And Trihexa will continue its destruction in the meantime. If that continues, the world will be completely destroyed. Our combat strength is also limited. Once, or twice, we may be able to hold it back, but there will come a day, when our strength is exhausted. Just like before, you saw what kind of a monster the opponent is, Issei-kun. It is a true monster that will completely regenerate no matter how you try to defeat it."

Issei didn't say another word, he just allowed Sirzechs to continue.

"Serafall, Falbium and I, as well as my peerage will depart from here to the 'Isolation Barrier Field' that was created by Azazel and the others specifically for use against Trihexa. We will also seal the original body and the core within that field. And be confined together with it. The higher ups of the other factions have also agreed to this plan."

"Then let me come with you! I can help you defeat Trihexa!" Issei stated, unable to move his body.

"You have done enough Issei-kun. Let the higher up's take care of the rest." Sirzechs said expecting Issei's resistance.

"Bu…" Issei went to say, but alas, Sirzechs didn't allow any more interruptions.

"Hush Issei, please, just listen to what I have to say. I am so proud of you. I'm proud of how you have continued to exceed all of my expectations. You're like a son to me and I am so proud, of the man you have become. I can't ever begin to repay you, for all you have done for me, and for Rias. For my family, I could never thank you enough, but there is one thing I can do…. I can seal away this imminent threat, and allow you and everyone else to live on in peace." Sirzechs said.

The proud maou took Issei into his arms and embraced him warmly.

"I'm proud of you Issei. I believe you of all people, can make a difference. You can live on for the future, keep the peace within the underworld, you could even become a maou one day. Not now maybe, but some day." Sirzechs said now letting Issei's body hit the floor again, as he returned to the portal of the isolation barrier.

"Sirzechs, please don't do this!" Issei said tears streaming from his eyes.

"Take good care of Rias for me, and of my adorable nieces and nephews okay? I hope to see plenty more little Issei's running around by time I come back." Sirzechs said now approaching his wife and queen Grayfia.

Sirzechs faced Grayfia, who lifted her head, and then created a magic circle which released some kind of technique towards her.

"Huh!? Sirzechs-sama, what are you trying to do!?" Grayfia said as Sirzechs mysteriously looked into her eyes.

Grayfia instantly fell to the ground. As if her power had been siphoned away.

"This is the special hypnosis technique that Azazel taught me. I thought that it would be useful on you."

"…W-Why would you do such a thing…?" Grayfia said as she struggled to keep her eyes open.

"I'm sorry, Grayfia. I hope that you can remain here."

"…You…really are…too cunning, Sirzechs…! …We clearly swore…that we would be together forever…!"

Grayfia's consciousness gradually faded, and she cried as she faced her husband, the person that she loved. Sirzechs also spoke with a tone of sadness

"For Millicas, in the days ahead of him…a mother is necessary." Sirzechs said as Grayfia collapsed into his arms.

Sirzechs walked over to Rias and gave her the unconscious body of his wife.

"And please look after Millicas and Grayfia for me, okay? Don't judge Grayfia by her appearances, she'll actually be very lonely, even more so than Rias. …When I'm not around, I hope that you can be there for her." Sirzechs said as he returned to the entrance of the isolation barrier.

"Please… Please don't do this." Issei said noticing that he couldn't do anything to stop the maou from making such a sacrifice.

"Goodbye Issei. My friend, my son." Sirzechs said disappearing in a flash of light, along with the rest of his comrades and warriors.

"SIRZECHS!" Issei yelled passing out, his energy finally giving out, his body fading, losing consciousness.

So Sirzechs like in the light novel, has sealed away the apocalypse beast Trihexa, sending a breathe farewell to his loved ones and his family. The next chapter will be the final chapter. Chapter 53: I promise to protect you all! The rise of the dragon children!
