Chapter 1 : Back in the wrong situation and time

Underworld, Capital of Lilith.

Issei was in his dragon form a while ago, not used to that huge body yet so he needed help from his Mitra, who was the original Dragon formerly nicknamed Red Emperor Dragon. Welsh Dragon Ddraig.

The phenomenon that Cao Cao did before was incomprehensible to Ddraig who had lived for more than a thousand years, this was the first time he had seen this incident.

[I've been hopping between hosts from different eras, also frequently encountering other Sacred Gear users. Including the True Longinus that he wields. But that power just now isn't from the Sacred Gear but the Holy Lance, Longinus itself.]

His explained in Issei's mind. He said after seeing and analyzing the power that was emitted that caused someone to be summoned.

'If it's like that, then this person must be something dangerous.'

[I agree with you, Partner]

After going on a short conversation, Issei managed to make good relations with Ddraig, the nature of Dragon is usually arrogant while Ddraig is the Dragon Emperor who is not only arrogant but with a slow approach that he does so that Ddraig thinks of Issei not as his host anymore but His friend.

After saving their curiosity for a moment, and focused on the one who had been summoned by Cao Cao with his life.

The man who was called, was still very young judging from his fit body and handsome appearance. and the angry expression on his face. His long hair reached his shoulders and was left loose.

His attire consisted of a leather vest, left shoulder guard, and animal hair wrapped around his waist that made him look like a hunter in ancient times.

"Damn you, Oberon!"

He shouted which made all attention focus on him, he looked up at the sky and screamed in frustration.

"Getting me stuck in sub-space like this!...come here, you coward!"

The man's scream had a negative effect. Rias felt trembling even Issei felt his adrenaline rising to make him want to go berserk.

That man is Takashi Akio, he is an unlucky human being sucked in by the spatial distortion that occurred 10 years ago.

He stopped drowning in anger and looked around to sort out the situation he was in now.

When his gaze ran and processed the information in his brain, he immediately concluded. what was happening to him right now felt real and not an illusion created by his rival.

Then his attention was locked on the lying corpse, the corpse's condition was so severe that the body slowly decomposed very fast and the black stain which was the poison continued to spread even after the person died.

so on, Akio walked towards the corpse but before reaching his, he nudged something at his leg, when he saw there was an almost broken spear.

Picking up the spear and turning Akio's attention to the spear and the lying corpse, then he got a little explanation from that.

"You are the one who called me?"

He muttered, then approached the corpse and knelt while turning the corpse's position to a normal position. He joined his hands together and put the spear back on his chest. while the other hand closed Cao Cao's eyes slowly.

"Anoo... who are you?"

Issei dared to ask Akio who was reminiscing about something, after finishing cleaning up the corpse. he stood up and turned to face Issei in his dragon form.

"Me?" smiled faintly and brandished his sword towards Issei.

"Human"

...

The chaos created by Cao-Cao has destroyed part of the capital city, then on the outskirts of the city, there are giant monsters that are clashing with the Devil's army led by the assistant and the strongest queen of the underworld at this time.

Grayfia Lucifuge. along with other comrades, held back the advance of the monster called Jabberwock which was 200 meters in size. continued to ravage the city with its large size and the ability to make smaller copies of itself making the situation worse.

Not only that. The monster named Bandersnatch, which was 150 meters in size, smaller than the Jabberwock was doing damage to the other side of the city. That made the capital city, Lilith now under attack a two-pronged attack.

As for the Bandersnatch, there were 2 Demon Lords who were fighting it and managed to bring the monster's movements to a halt, however. The smaller copies of the monsters were still scattered making the two Demon Lords have to prioritize civilians first and couldn't help Grayfia who was against the Jabberwock which is much larger than the Bandersnatch.

Although not assisted by the two Demon Kings, Grayfia. gets help from a very large dragon. its size is very large, exceeding the size of the Jabberworck Monster. even that shadow of the dragon covers the entire capital city of Lilith. However, the help received by the Devil's side is very small because the dragon only gave small attacks to the Jabberwocky, and only made the monster's movements stop for a moment. even though it was a small help, it was very meaningful for the Devil's side to prepare for a large-scale attack.

But amidst the fierce battle from all directions, an extremely conspicuous phenomenon grabbed their attention as well as an extremely stifling presence. Just his screams could be heard by everyone who was fighting within 5 kilometers. Those who were experienced in fighting would understand, if The only creatures that could make that roar were Dragons and Calamity-grade Monsters, like the ones they were facing right now.

"Tch!... Did another monster appear again?!"

Grayfia couldn't focus because the roaring sound came from her young lady, who had a close relationship with her. Even though their status was only master and servant,but she love her ;ike her own sister.

She is Rias Gremory, she at moment with the Sekiryuutei facing a new, more dangerous threat from the two monsters that are wreaking havoc on the capital now.

"Ojou-sama...hope you are still okay"

Even though she wanted to meet her immediately, Grayfia couldn't do that because the Jabberwock monster hadn't fallen yet. She could only hope that the Sekiryuutei could protect her.

"Miss! We have to freeze this monster! before he wakes up again"

Shouted her partner who immediately woke Grayfia from her reverie. Immediately she did her job again, which was to paralyze the monster.

...

Back at the same place. At this time Issei received a warning from his partner if he had to immediately attack the person in front of him at this time. But Issei hesitated because this man looked harmless. For now, he had to make Rias away from that place.

"Rias-san"

"Um?"

"Could you please stay away from here...please"

Issei even begged Rias to get away from that place immediately. Rias's response was initially hesitant to leave him alone but seeing he was serious, Rias complied.

"Be careful...I just got you again and I, no...everyone doesn't want to lose you again. Issei-kun"

"Hmm...I see"

Even though it was hard to leave Issei alone, she had to stay alert from a distance, monitoring the situation of her lover who had just returned.

After Rias flies away, the tension is now between the two creatures. Even though Issei has just returned from death and gained a new form and strength, as a Dragon. He is still not used to it and relies on his partner to teach him to fight in his Dragon form.

The current war situation is dominated by Devils, so most of the terrorists have lost their respective battles. It is only Akio who has just realized his current situation and must immediately make a choice. Help the terrorists or negotiate with the devils. Because he is an outsider who happened to be dragged into this matter.

However, Akio had already made a choice. When he saw the lying corpse and the nearly broken Holy Lance It gave him a purpose. Why was he summoned by Cao Cao with his life?

In a state of calm and full of vigilance, Akio moves his sword that has been implanted by Aura. So that the sword slash has great damage.

*SRIIIIING!*

The attack was so fast that it made Issei's response slow down, plus he wasn't used to such a big body yet.

"ARRRRRGH!"

He managed to dodge, thanks to Ddraig. However, one of his wings snapped off, causing a shriek of pain that was heard by everyone within a one-kilometer radius.

"Issei!"

Rias felt horror again when she saw her lover's wings break. She didn't want to feel that feeling anymore. She didn't want to lose Issei again for the second time. Then she ignored Issei's orders and threw a large-scale attack on Akio.

[Power Of Destruction] bloodline power goes berserk so that it destroys objects around Rias. She attacks Akio with that power.

However, something unexpected happened, when Akio attacked that attack with the same force that severed Issei's flank.

[Vertical Slashes!]

The slash cut Rias's [Power Of Destruction] into two pieces and allowed her to escape destruction. The attack destroyed two sides of the ground from where Akio was standing.

The attacks didn't stop, though Rias was surprised by the fact his [Power Of Destruction] could be slashed by Akio. That gave Issei a chance to attack him from his blind spot.

*KLANG!*

The clash of metal, and dragon claws was inevitable. Akio was pushed back by Issei's immense power so he backed up a few meters. But, He attacked again with another large-scale attack.

[Canon's Aura Blade!]

His piercing technique possessed unreasonable power. Issei almost lost again but luckily he maneuvered well, he was getting used to his dragon body. However, he didn't have time to be happy for a moment, because the sight of Akio's attack took him by surprise. Stab crossed the city killing many people in one go, and the trajectory of his attacks seemed endless.

Seeing that, Issei exploded in anger and attacked Akio blindly, not only Issei exploded in anger, Rias who was watching the scene was angry that Akio destroyed the city and brought suffering to its inhabitants.

Rias could hear the suffering the civilians were going through. Screams for help and cries added to her anger. This time she focused her attacks on a single point. Her technique would completely devour Akio due to the wide scale of the attacks.

But it wasn't just Rias, when Issei managed to catch Akio off guard with his tricks, he took out his best attack.

The mechanical voice kept saying the same words.

[BOOST!] [BOOST!] [BOOST!] [BOOST!] [BOOST!] [BOOST!] [BOOST!] [BOOST!] [BOOST!] [BOOST!] - - - - - - - - [BOOST !].

In a short time, Akio felt that Issei's strength had increased drastically in a way he had not yet known.

"FEEL THIS!"

Rias and Issei shouted simultaneously, while their strongest attack was thrown at Akio, who was ready to deal with the attack.

[Longinus Smasher!]

The combination of these two powers creates an attack with a wide area when it reaches the target. In front of that attack, Akio focuses every energy flow in his body, on his sword blade. So the sword's blade emits a bright blue light.

[Grand Chariot: Seven Star Power]

[First Star: Dubhe]

After muttering the name of his technique, Akio swung the sword was already compressed by power. Then a beam of light rose until it clashed with the combined attacks of Issei and Rias. It made the sky of the capital light up in an instant.
