<~~~~~~~~~~~~~~~~~~~~~~~~~~>

In the dark night that covered the school field at Kuoh Academy, there were several people seen fighting with someone who had 10 wings behind them, the person was wearing a black robe with detailed accessories and purple shoulder pads with gold streaks on the side.

"Don't mess around! I can't let you destroy my town. My comrades. President. And Asia. Just for your selfish motives! And I'm going to become a Harem-king! I would be troubled if you get in my way!"

A man with brown hair and red gauntlet on his left hand shouted at the person.

The others who heard the words from the man with brown hair could only stare at him with a strange look and shake their heads because they were used to his behavior by now.

But as they were discussing something, suddenly the man with 10 wings, or Kokabiel, stopped and looked at something.

Not only him, but someone flying and watching them also looked at something in the same direction as Kokabiel.

"Hey! Don't ignore me!" the man with brown hair seemed annoyed because Kokabiel seemed to be ignoring him and looking at something else.

"Issei, just be quiet for a moment!" the red-haired girl with a chest like a Draph said to the person named Issei.

Although the girl just a lazy otaku who only wanted to watch anime all the time, she still had good instincts.

The girl also looked at what Kokabiel was paying attention to and confused about what she was feeling at that moment.

Suddenly, cracks appeared in the air, gradually increasing. Each crack made everyone there shiver as they started to feel a strong aura.

Kokabiel looked focused and wondered who had an aura like this. Although he had been involved in the war between the three factions before, he had never felt an aura like this before.

But suddenly the pressure of the aura they felt disappeared as if its aura had never appeared from the beginning.

They all remained silent and watched the dark place appear after the crack broke.

And then they saw someone emerge from that dark place, the person had white hair and looked like a human(?) And wearing some kind of cloak?.

After the person came out, he began to check his surroundings but when he saw their faces, he looked surprised.

"What the fack!" They all heard the person speak.

<~~~~~~~~~~~~~~~~~~~~~~~~~~>

Currently, Rei is confused when he looks at the faces of the people around him.

Initially, he wanted to open a portal to his world after fully obtaining Lucilius's power and it had stabilized, but he ended up getting lost in another anime.

When he saw who was around him, he remembered that the characters were from the anime Highschool DxD that he had watched years before. He didn't really follow the series and stopped at season 2, but he still remembered this scene where Issei and the others fought Kokabiel, who wanted to start a war again by killing Rias and Sona to anger their Brother and Sister, who held the title of Satan, and start a war.

He immediately wanted to go back through the portal he had created and leave this strange world where almost all the women had chests like Draphs, but before he could enter, he heard someone speak.

"Who are you?"

He heard Kokabiel still floating and speaking to him, but he ignored him and wanted to enter his portal because he didn't want to be there. Suddenly, he was bumped by someone who also wanted to leave the portal.

They saw that the person who bumped into Rei was a girl wearing the same cloak as the person, but she didn't cover her body and only covered her head.

"Ouch!" the girl fell because she didn't expect to bump into Rei as she exited the portal.

Rei immediately helped her up and apologized to her.

Issei, seeing the girl's chest as large as Rias's and she didn't cover most of it, immediately had a nosebleed and started mumbling something that some of them heard, "Oppai~ hehehehe~"

"Why do you want to go back in, Rei? Don't we usually want to check first whether this world is yours or not as usual?" The girl spoke to Rei.

Rei heard this and shook his head while saying, "No, no, this is not my world Sturm. By looking at their faces here I'm sure, because in my world there are no people like this."

Rei immediately pulled Sturm's hand and tried to bring her back into the portal to search for his world again, but Kokabiel, who was being ignored, became angry and threw a spear of light at the two of them.

The spear of light aimed at both of them, who was turning away from them all to return to the portal.

"Watch out!"

Rias and the others panicked and tried to help them, but their bodies were still weak from Kokabiel's attack, and some of them were shocked after hearing that god is already death.

But the spear of light thrown by Kokabiel suddenly stopped when it was about to hit Sturm.

They all started feeling the pressure that they had felt before, but this time it felt stronger.

Kokabiel, who was at the center of the pressure Rei was emitting, started trembling and finally fell because he couldn't handle the pressure.

"Ugh...." Kokabiel tried to get up after falling, but his body continued to tremble, making it difficult for him to stand up.

Rei turned towards Kokabiel and they all could see his eyes covered by the cloak glowing blue.

"You!" Rei looked very angry when Kokabiel was about to attack Sturm.

The spear of light floating near Sturm began to floating towards Sturm backs to protect her, while Sturm just smiled seeing Rei like this.

Every time Rei gets angry because she getting hurt or someone wants to hurt Lyria or Djeeta, it always makes her face warm and her heart beat faster.

Rei raised his right hand towards Kokabiel and pointed towards him using his two fingers.

"Axion."

Two light beams came out of his fingers and went directly towards Kokabiel. This attack was only meant to harm Kokabiel because he knew Azazel wanted to bring him back alive and Vali was watching them.

But they all didn't know that what they felt from Rei's attack was *Death* so suddenly they heard a voice.

[Divide]

Rei's attack seemed to shrink and its light diminished, but the attack still went towards Kokabiel and finally hit him.

"Aghhh!" Kokabiel felt like his body was burning when the light hit him.

Kokabiel writhed in pain, the feeling of burning not dissipating.

Suddenly, someone landed near Kokabiel. This person was wearing white dragon armor with blue wings behind them.

They checked Kokabiel's body and apart from the wounds from Rei's laser, they didn't find anything.

But strangely, Kokabiel was still writhing in pain, and finally the person in armor turned towards Rei.

"I know this person almost attacked your friend, but can you stop this and let me the one that deal with him?" They heard his voice as He said that to Rei.

Rei, hearing this, just shrugged and snapped his fingers, and finally Kokabiel stopped writhing and lost consciousness because the pain he feel is exceeded normal pain he usually feel and even the one he feel before.

Rei then turned back and returned to Sturm and wanted to enter the portal, but the person spoke to Rei again.

"I have never seen someone like you... and from this feeling I know you are very strong. Do you want to fight me?" He said to Rei.

Rei started to remember that the person wearing the white armor was Vali Lucifer, who is a battle maniac and always tried to fight against someone strong, even gods who were in other place.

He about to refuse him but suddenly he saw Sturm nodding with her eyes filled with excitement.

Seeing Sturm like that made Rei's eyes twitch because he knew Sturm wanted him to accept Vali's offer to fight because she wanted to see Rei serious and unleash his black wings.

Since Rei mastered the power of Lucillus, he rarely used his black wings and only used his white wings, so Sturm wanted him to occasionally use his black wings.

Rei sighed and turned towards Vali, saying, "Alright... but just for a short while, okay? I'm a bit busy and want to return."

Hearing that, Vali nodded and asked Rei, "So, do you want to fight in the air or just on the ground?"

"Since my fiancée wants to see my wings, it doesn't matter if it's in the air," Rei replied.

Upon hearing the word "wings," Rias and the others became convinced that he was not a magician but definitely supernatural creature.

Suddenly, Issei's gauntlet began to glow and something spoke from it,

[Have you forgotten about me White?]

Upon hearing this, Vali's wings also began to glow, and he responded,

[Red? It seems you're awake now, but judging from your user, it looks like this time you have a troublesome one].

[Hahaha, even so, don't underestimate my user; despite his quirks, he has a strong determination like a red dragon user should. Although his behaviors is a bit strange.]

Issei looked annoyed because admiring oppai is not strange but rather something beautiful.

"Enough, Albion, let's focus on the person in front of us. The red dragon user is still very weak and cannot fight with me right now," Vali addressed Albion, focusing on Rei, before flying up and waiting for Rei.

Rei saw this and finally took off his cloak and handed it to Sturm.

They were all shocked to see Rei's handsome face and beautiful white hair.

Meanwhile, Issei was getting more annoyed as he saw someone so handsome like Kiba. "Damn... that handsome face, Kiba," Issei grumbled, while Kiba, standing next to him, could only look at him with a blank expression.

Rei turned his gaze towards Vali, who was waiting for him in the air, and finally unleashed his 12 black wings that Sturm wanted to see.

They were all even more surprised to see Rei's 12 black wings. Rias and the others had never seen 12 wings on a fallen angel besides Azazel and were curious about who this person was.

Rei flew up to be level with Vali, who was waiting for him.

"You? Are you a fallen angel? I have never seen a fallen angel with 12 wings like you other than Azazel... Who are you really?" Vali asked, looking serious as he stared at Rei's wings.

"Who I am isn't that important, and besides, you have already heard my name from my fiancée. You can call me Rei," Rei replied.

"And you just want to try fighting me, so I'll entertain you. So, are you ready?" Rei asked.

Vali heard this and removed his armor mask showing him smile. "You're right, who you are doesn't matter to me. What's important is that you fight me seriously!"

Upon hearing this, Rei called his sword, and suddenly a golden light appeared in his right hand, summoning a golden sword that he held immediately.

[Uh-oh, Vali... I can feel a very strong aura from that sword. If you get hit by its attack, I suspect this armor won't be strong enough to withstand it].

Hearing Albion's comment, Vali smiled and looked eager to fight such a powerful opponent, preparing himself.

Rei continued to observe Vali and began to think that he wanted to end this quickly using his ability Phosphorous.

Phosphorous was his sword ability that nullified and negated any statistic amplifications and some abilities.

This way, Divide would not be useful against Rei, but he wanted to play a little longer so that Sturm could see his wings for a while longer.

Rei began to emit his aura, causing everyone to feel a sense of pressure, except Sturm who seemed very happy at the moment.

Rei lifted his sword and pointed it at Vali, while Vali put on his armor helmet again and assumed his stance.

They both continued to gaze at each other, waiting for one of them to make a move.

Suddenly, Rei disappeared, startling Vali as he didn't see Rei move at all.

Seeing him vanish, Vali sensed danger and swiftly dodged by flying to the side.

Rei swung his sword at Vali's previous position, creating a strong gust of wind felt by everyone witnessing their battle.

"Ughhh," Vali felt the strong wind, trying to hold on to avoid being thrown off.

"Wow... I didn't think you could evade that, it seems like your instincts are good," Rei turned towards Vali.

Though he said that, he was certain Vali could evade his attacks because Vali was a battle maniac who loved to fight, So Rei believes in Vali's instinct to avoid his attacks

Feeling the swing of Rei's sword, Vali grew more excited and began attacking Rei, but Rei kept evading.

Vali still hadn't used Divide, as he wanted to see how strong he was compared to his opponent.

After a while, Vali still couldn't land a hit on Rei and finally used Albion.

[Divide]

Rei heard the voice of Albion and allowed him to cut his power in half, but then Vali who was attacking him suddenly stop moving.

[Overload]

"Eh?" Rei was confused as he didn't remember this overload.

Vali's body was filled with energy, and before Albion could release some of it to prevent an overload, Vali's armor disappeared.

Vali's body was pulsating, unable to contain the power he absorbed, and he started to fall.

Rei caught Vali before he fell, realizing that he had passed out and his body was starting to deteriorate from within.

His body was bleeding profusely, and if left untreated, he could die. However, Rei eventually used his energy from Lucifer ability to heal Vali.

He sighed, feeling a bit anticlimactic, and he was sure Sturm would be upset with him.

After that, Rei slowly descended while carrying the unconscious Vali and laid him on the grass.

He then looked at all of them who seemed to be watching him cautiously because they thought he was a fallen angel, especially after easily defeating the white dragon emperor.

Rei then sighed after seeing their expressions, but suddenly he stopped staring at them and looked towards Ddraig, who was in Issei's left hand.

Rei thought maybe he could create a primal beast with the ability to boost and divide like Ddraig and Albion to give to others in the sky realm.

Issei, seeing that the fallen angel was paying attention to his Sacred Gear, started to cover it, thinking he might try to take it like what happened with Asia.

Seeing his abilities when fighting the white-haired man that Ddraig said was his rival, Issei knew he was not his opponent and he could easily kill him.

The others also realized that Rei was looking at Issei's Sacred Gear and hoped he was just curious and did not want to take it.

They were all beaten up and tired because of the incident with Kokabiel, so it was impossible for them to stop Rei if he wanted to take it.

Rei then looked up and saw the barrier created by Sona and her peers to minimize the damage during the fight against Kokabiel was starting to disappear.

After this, he knew Sirzechs and Serafall would appear, and maybe Azazel would also appear because he must have known Vali was unconscious after sending him to bring Kokabiel.

He then began to make the 12 black wings on his back disappear and quickly walked towards Sturm, who was pouting at him because the fight between Rei and the man in armor ended too quickly.

"Sturm let's go back to the portal before the portal I created closes and we got stuck here," Rei grabbed Sturm's hand.

Rei needed a lot of energy to create a portal to another dimension, and if that portal closed, he would need time to create another portal to a different dimension.

Hearing that, Sturm nodded, and the two of them started walking towards the portal before two Satan and the leader of the fallen angels appeared, and Sona and the others too.

He didn't want to be stuck in this strange world and wanted to return to the sky realm quickly.

"!?" Suddenly, Rei felt someone grabbing his left hand and trying to stop him from returning to the portal.

Rei then turned to his left hand and saw Rias holding onto it while trying to stop him.
