(Your POV)
I was sent flying into a nearby hill with my entire chest cavity torn open, allowing [King's Body] to kick in and regenerate my body, covering it in golden scales in the process. I dodged another orb of black flames by using [Holy] to leave behind a clone of me to take the hit in my stead. I was currently fighting Estarossa, the former Commandment of love before he died sometime ago under mysterious circumstances. I knew his abilities, and it appears he knew mine as well. I'm going to blame that one on Ursula. To be honest, I'm only fighting this guy because I'm completely immune to his commandment's ability to neutralize people with hatred in their heart.

"You're holding up quite well." Estarossa complimented while I looked at my body, noticing that my entire right arm and chest were now covered in golden scales. "However, this here is a war, so you should let the big guys do the fighting. After all, you're only relying on your immortality."

"You should know better than to insult a king, you Mongrel." I said in a cold voice while golden colored circles of light began to appear behind me like a wall, surprising Estarossa. "Use skill: [GATES OF BABYLON]!"

The moment I said this, all my weapons peered from each individual circle, and if you didn't already know, having every video game weapon in existence and combining it with a skill that launches your entire inventory at your opponent tends to have massive effects. In sync, every single weapon shot it towards Estarossa, who gazed at the sheer amount of weaponry in horror, he managed to block two swords that were coming at him, but I wasn't exactly feeling merciful today. I weaved my hands into a series of hand signs and felt electricity flowing through my arms.

I used [Flash Step] to appear directly behind Estarossa to deliver a vertically aligned punch of the neck and lower back. Uptown contact, the Justu I used called [Magnet Style; Babylonian Target] magnetized Estarossa's Body, causing all of the metal weapons launched towards Estarossa like homing missiles. Estarossa began trying to use his sword to deflect as many weapons as he could, but a massive hammer caught him off guard and caused him to be sent flying back.

"[Ice Make: Draconian Pillar]!" I had my hands in the ice-make formation, causing a pillar made of blue ice to appear behind Estarossa, along with a serpentine dragon coiling itself around it. "[Ice Make: Finger Bullets]!

Estarossa landed in the pillar, causing it to dent a bit with a crater, the serpentine then wrapped its body to cover the hole like a barrier. While my hands were still in the ice-make hand sign, I pointed my upper pointer finger at Estarossa, then I mimicked a gun firing. A cluster of ice spikes suddenly appeared, piercing Estarossa's body as all the tips faced away from me. In my opinion, the move kind of looked like Todoroki's heaven piercer on a much smaller scale.

All of the metal weapons weren't stopping though, they were still heading towards Estarossa with murderous intent. Upon impact, my ice was shattered completely and the sound of metal closing could be heart. Shards of ice and frost covered the area, however, I still managed to feel a disturbance. I used [Seiryu] on the place where Estarossa supposedly was, and realized that he was impaled everywhere, yet he was still standing. That move should have killed him or at the very least severely injured him.

"Impressive, you managed to stab 4 out of 7 of my hearts." Estarossa complimented me, I took notice that the lower half of Estarossa's torso seemed unharmed. "So how I only have three left."

"I expected no less from the former Commandment of Love." I smirked and weaved my hands into another series of hand signs and activated [Helios] at the same time. "Use skills: [Disaster Style: Grand Tornado Warning] and [Helios: Ring of Fire]."

A tornado appeared around Estarossa, with the size of the tornado being the same as that skyscraper we came from. Around the tornado a ring of flames appeared, which was sucked in by the tornado I made to become a flaming tornado. I dismissed all of my weaponry and wrapped my cloak closer around me. The cloak's furs were rather comfortable, and the length of the cloak was able to cover my entire body. That's not to mention the other function of the cape, it managed to turn parts itself into chains that blocked a sword strike, I merely turned my head to see Estarossa was the one who slashed me.

"Nice try, but you call that a sword slash?" I asked while extending my arm a bit from my cloak to summon [Areadbhar]. "Let me show you how you swing a weapon, [Atrocity]!"

I forcefully swung my spear, leaving behind a glowing red slash mark complimented by black lightning. Estarossa's arm was cut clean off, and the terrain behind him wasn't unaffected either. The ground up to 10 meters away was also cut. However I wasn't done, I used [Ryokuryuu] to turn my right leg into a dark green dragon's claw before delivering a surprise sweeping kick to knock Estarossa off his feet. Unfortunately the demon managed to dodge and deliver a knee to my face, one that was strong enough to snap my neck and displace the bones of but. Luckily, [King's Body] managed to repair the damage in an instant thanks to [Ouryuu], it also made my neck a lot stronger.

I used [Warp] to turn myself into light and reappear behind Estarossa before biting my thumb to let some blood out, I then used the blood after weaving a series of hand signs to use [Summon: Alatreon] by slamming one hand on the ground. A blue smoke covered the area we were standing at before I felt myself get elevated. When the smoke finally cleared, it was revealed I was standing on top of the head of a alatreon. The alatreon roared loud enough for the entire battlefield to hear, even though everyone else was around 50 meters away from us, I'm sure they heard it.

"So Estarossa, do you have a moment to talk about our lord and savior?" I asked with my eyes closed in pride.

"Um, no..." Estarossa was obviously confused. "Why?"

"Cause you're about to see him soon." I opened my eyes and used [Seiryu] to attempt to paralyze Estarossa. "Alatreon!"

Alatreon dived down towards Estarossa whilst covering itself in electricity, forcing Estarossa to dodge by jumping into the air and staying there. I summoned [Chastiefol] and sent the spear towards the demon, surprising him because I was using such a familiar weapon to him. Still, he managed to deflect the spear with his sword, but he didn't expect me to use [Chastiefol, Fifth Configuration: Increase] to split the spear into many small blades to begin circling around him. While he was distracted with the blades, I was beneath him  and began charging up a breath. I faced my head upwards and used [Ocean D.D.G Slayer: Dragon God's Devil Call] to send a powerful breath attack towards Estarossa. The breath attack was mainly composed of highly pressurized water encouraged in black lightning and had shards of purple ice in it.

The breath attack hit Estarossa dead on, making him disappear in the water while Alatreon dashed upwards in an attempt to bite Estarossa. Surprisingly, Estarossa only came out with some minor cuts from the initial attack, maybe I actually will have to go all out with this guy. I activated [Ryokuryuu], [Hakuryuu], [Ebony Skin], [Jack the Ripper Mode], and [Armiger Variant: Seven Deadly Sins]. [Armiger] and [Gates of Babylon] were two of my most developed skills, and they had variants based on what weapons I used. Like Armiger Variant: Seven Deadly Sins makes the sacred treasures circle around me like normal weapons would. Anyways, I used my enhanced speed and strength to move around the arena while Estarossa was busy with Alatreon's elemental attacks. When the demon realized I was missing, it was too late, I used [Divine Axe Rhitta] to cut Etsarossa's arm off. My opponent tried using his own full counter, but I delivered the attack before he could even react.

"You know buddy, now you can just surrender." I suggested as the weapons still circled around me. "Over the past three years, I've trained under all the (L/N) clan peerage members,except for my own, and now I'm fast enough that even they can't keep track of me. That includes Kars and Meliodas, even though the latter is just freeloading."

"So you know Meliodas, that explains the familiar fighting style." Estarossa commented as he prepared his sword. "Enchanted hellblaze."

"Use skill: [Water Style:Great Pyramid of Atlantis]." I countered Estarossa technique by engulfing the two of us in a massive pyramid made of seawater, and the size of the pyramid is comparable to a pyramid in Giza. "By the way, Alatreon can breathe underwater."

"Huh?" Estarossa turned around the see the dragon in question generating some electricity around it's body before breathing a massive amount of it towards Estarossa.

"Use skill: [Fish Man Karate: Samegawara Seiken]." I punched forwards, causing a shockwave to appear from my fist, then Etsarossa's body started moving like it was being punched in all directions.

Not only was Estarossa being attacked from all directions but he was also getting electrocuted by Alatareon's breath attack. I couldn't see the demon anymore, and I was getting annoyed with the electricity damaging me too. When Alatreon finally stopped, it revealed a charred Estarossa was now floating aimlessly in the pyramid of water. I had assumed he was dead, but then a blue orb flew out of Estarossa's chest and started flying away, supposedly back to Ursula.

If this is a sign of how the war's gonna go, then my plan is gonna need some adjusting.

(Scene change brought to you by Alatreon breathing flames into the camera)

(Author POV)

Yoshino and Chaos were both taking cover behind a concrete pillar to avoid the icy wind that was being sent towards them by Doma. Yoshino was pretty much immune to Dona's powers, but she knew Chaos had a limit to how much cold he could tolerate. Plus Chaos was more of a utility and support piece than a fighter, plus his only method of fighting was with a hammer that he made to resemble Nora's, complete with a built in railgun. Plus she was also dealing with Akaza, who managed to deal some heavy damage to Chaos' body.

"My my, hiding are we?" Doma suddenly appeared above the duo with the usual smile on his face being covered by his fan. "I must say I feel awfully bad for killing a couple of children, but I'm afraid Ursula ordered us to, so be a dear and go silently."

Yoshino grabbed Chaos' hand and pulled him out of the way of a series of ice needles that were heading towards him, then she began running in hopes of finding at least one of (Y/N)'s servants to help them out. Yoshino knew she could easily take on Doma and Akaza by herself thanks to her father's training, but the downside of her angel is that she fears it would hurt Chaos. All she needed was an opportunity to release Zadkiel without harming Chaos.

"There's no point hiding!" Akaza appeared above Yoshino with his foot raised, making the small girl freeze for a moment in fear before an audible roar could be heard. "Huh?!"

In that moment, Akaza was distracted by the sound of the roar, allowing Yoshino to not only keep running, but also find a safe spot for the severely injured Chaos to take a breath and recover. Yoshino leaned the boy's back against the cover before the teenaged girl stepped out to face the two resurrected demons before her. Yoshino summoned her astral dress, which remained almost the same, and the only difference now was that the size of the outfit matched to suit her new height. Compared to the girl that (Y/N) once met, Yoshino was unrecognizable. She still had some of the same quirks, but now she knew not only how to protect others using her power, but why she's fighting.

"How brave of you, taking on the two of us all by your lonesome." Doma attempted to shake Yoshino's nerves, a trick that the spirit is immune to because of her experience with the AST. "In respect for you, I'll give you a quick death~."

"With all due respect, your ice is warm compared to my own and nothing to my father's." Yoshino brushed off the cold like it was nothing before raising one of her hands to the air. "Zadkiel!"

Zadkiel suddenly appeared, causing the area to be engulfed in a freezing cold mist, but something was different about the giant rabbit puppet. For starters, now it had armor made of ice and Yoshino was controlling it via blue strings from her fingertips. In an instant, Akaza charged towards Yoshino, making the girl summon a series of ice spikes on the ground below the two demons, forcing them into the air. Now that Akaza and Doma were in the air, Yoshino opened Zadkiel's mouth to fire a beam of white light from it, Doma attempted to block it using his fans, but then he was shocked by lightning.

"Not this time." Chaos shouted from his cover, all while he held some kind of device that looked like a lightning bolt, when in actuality it was a grenade. "Yoshino, duck!"

Yoshino, who was riding on top of her puppet Zadkiel, ducked and made the puppet jump back to avoid Chaos' thrown grenade. The grenade landed directly in front of Doma and Akaza, neither of whom have seen a grenade before and accidently let their curiosity get the better of them. Well, Doma was going to try and shoo it away, but Yoshino's beam managed to freeze his arms in place. The grenade suddenly blew up in the demons' faces, causing something like a lightning strike to appear on the spot.

While both demons were phased by the blast, Yoshino summoned a series of icicles above Doma and Akaza. However, Akaza managed to snap out of his initial shock and jump into the air to kick the icicles away with a flurry of kicks. At the same time, Akaza managed to use his blood demon art to make several ice clones of himself to attempt to surround Yoshino. However, all of the clones were blasted away by a series of familiar blue arrows of mana, everyone raised their heads to see Jihan calmly soaring above everyone with his staff in hand.

"Sorry for making you two go through that." Jihan landed on the ground and summoned a sphere of spinning mana in his palm. "You two can get out of here."

"Thank you for your help, but I'd like to fight these two with Chaos." Yoshino said, causing Jihan to look at her in a surprised manner, she certainly wasn't the same spirit three years ago. "I'm tired of running and hiding, we're in a war now, I want to help my father."

"Who are you and what have you done with Yoshino?!" Jihan shouted and pointed a finger at the girl, who sweatdropped and smiled a bit. "In all seriousness, let me heal Chaos first..."

"Not happening!" Akaza appeared behind Jihan and attempted to deliver a kick, but a wall of solidified mana so thick you couldn't see through it suddenly appeared to block the kick. "Huh?"

"Look buddy, not only am I level 936 now, but I also trained under Leader of the Mana Mafia and Lolikano for three years, I'm way out of your league." Jihan then places a hand on the barrier, causing blue mana to erupt from the other side of it. "Use skill: Mana Overdrive."

"What on Earth!" Doma shouted in fear at the sight of the amount of mana, which looked like enough mana to engulf a one story building. "At least Akaza's gone, he was annoying."

"I'm still here..." Akaza regenerated from the overwhelming amount of mana while Jihan walked off to heal Chaos.

With that said, Yoshino used her angel to jump into the air and attempt to deliver a slam onto the ground, forcing the two demons to separate in order to stay uncrushed. Akaza landed to Yoshino's right before the sound of a beep could be heard, Akaza looked down at his feet to see that he landed on a landmine. Akaza thought he could regenerate from it, but when the mine blew up, Chaos pulled a rod of iron from the rubble and ran towards Akaza. Akaza was obviously confused by this as he blew up, and his legs were about to attach back onto his body before Chaos cauterized the wounds on the legs.

Catching onto the idea, Akaza tried using blue bursts from his torso to get away from the blonde, but it was too late, Chaos was using his gauntlets to heat up the metal. The reason why Chaos wore those gauntlets was because they were basically the closest thing to a utility belt he had, and they provided a series of uses such as heating metal, shocking people, and more. Akaza's arms were now all cauterized, leaving the torso to fend for itself while Chaos walked towards the demon.

"You fought well against the embodiment of chaos, now rest up." Chaos plunged the metal bar into Akaza's forehead, causing it to appear on the other side. "I couldn't afford to lose, I need to protect someone close to me."

On the other hand, Yoshino was holding out fairly well against Doma, after all, she did train with Kurumi and her father over the years to get better at using her spirit abilities. Yoshino summoned several pillars of ice around a confidently laughing Doma, then Yoshino clenched her hand, causing the ice pillars to crush Doma. Surprisingly, the demon jumped into the air and sent several ice needles in front of the girl. Yoshino barely reacted before turning the ice needles into water she was able to freely control.

Taking a deep breath, Yoshino turned the water around her into ice spikes that were roughly the size of Doma before sending all the spikes towards him. Doma deflected all of the spikes flamboyantly before bowing before Yoshino to taunt her. Doma raised his head with a smile, but it quickly faded upon the sudden realization that the girl was nowhere to be seen. Doma looked up to see Zadkiel was crashing towards him, so Doma jumped back and into the air to prepare his fans. Once Zadkiel crashed onto the ground Doma used his fans to send a powerful gust of wind towards the puppet's back, but he couldn't see it's back because of the dust.

"You fought marvelously, but there are some things even spirits can't do." Doma complimented before clapping his fans together, creating a metallic sound to them.

"I can say the same thing to you." Yoshino revealed herself behind Doma, shocking the demon but he couldn't react, his limbs and torso were all covered in ice. "You would have beaten me, but my angel is far superior compared to your blood demon art."

"My my, I heard you were a sweet little girl, whatever did happen?" Doma asked with a laugh, despite his deadly position. "Don't tell me the war changed you already?"

"No, after the fall of Sacred King's, I realized that I'm just wasting my abilities." Yoshino recalled as the ice started crawling up Doma's neck. "I'm a spirit, not a coward, so I figured I should act as such. I had Kurumi and my father train me, and now I can not only defend myself, but protect others too."

With that said, the ice finally covered Doma's entire head, Yoshino snapped her fingers and the ice suddenly shattered apart. Almost in sync, Akaza and Doma's remains summoned a blue orb that suddenly flew off in the distance, back to Ursula. Yoshino suddenly remembered Chaos' condition and quickly began running towards the boy while dismissing her angel and astral dress, leaving her in her usual outfit. To Yoshino's surprise however, Chaos ran up to her and embraced her into a tight hug, making the spirit blush.

"Yoshino don't go fighting someone like Doma on your own!" Chaos ordered the girl, who was still speechless because the one she loved was hugging her right now, but the hug was cut short by Chaos growing shy too. "E-Even If y-you are a spirit, you're still a princess!"

"I can say the same to you!" Yoshino learned to get over her shyness via (Y/N)'s training, which was far more survivable than Saorise's, but was still mildly uncomfortable and annoying. "You may be a pawn, but you shouldn't throw yourself into the face of danger!"

"My my, is this a lover's quarrel?" Arden appeared between the two via unknown means, but his statement still made both Yoshino and Chaos cross their arms before looking away with red faces. "Go on children, don't be shy. You can trust your Uncle Ardyn."

"What's going on over here?" (Y/N) appears with the alatreon following close behind like a dog. "Is someone bothering you two?"

"N-Nothing, Chaos and I just managed to take on Doma and Akaza on our own is all." Yoshino says proudly, this made (Y/N) go pale for a minute before proudly headpatting Yoshino's head. "Hey! I'm not a kid anymore!"

"EH?!" (Y/N) looked genuinely shocked and even recoiled at the sight of a pouting Yoshino. "But everyone likes headpats! Why gods, why does my little girl have to grow up so fast!"

"She was even having a lover's quarrel with Chaos over here!" Ardyn went on with his usual mischievous smile, causing Yoshino to try and signal to the immortal for him to shut up.

"I'm sorry, come again Ardyn?" (Y/N) smiled as some of his hair casted a shadow of his eyes, followed by a storm suddenly appearing in the sky, signaling that he was in a bad mood.

"He said a brother's quarrel!" Yoshino lied whilst covering Ardyn's mouth with her hand. "You know how I see Chaos as a brother and all, since he's the guard you assigned to watch over me."

"Aw..." Chaos' head hung low despite his victory, he thought the girl he loved brother zoned him.

"What do you mean 'aw'?" Ardyn teased the boy with an amused smirk, somehow escaping Yoshino's grip in the process.

"That's good to hear." (Y/N)'s smile returns as the storm above them suddenly disappears, confusing Alatreon. "Back to the matter at hand, I guess we're officially at war with the western gods."

"Indeed, it would be best for us to help our allies so they can help us as soon as possible." Ardyn suggests before he tilts his head in confusion. "By the way, why weren't there any other god representatives in the meeting?"

"Like I said, everyone's doing their best not to get invaded." I reminded the immortal as Sung, Coyote, and Jihan walked over to me. "The gods from India are the most powerful because they're still practiced, so they should be fine. Still, they're playing it on the defensive because our enemy also has British myth on their side. European gods' specialty is invading other countries."

"So what's the plan boss?" Sung asked as he dismissed his dagger in a flash of light blue electricity.

"Like I said, we're gonna find spirits, eradicate grimm, and support our allies." I said with a confident smirk, watching as the sun set off in the distance. "Plus I have my secret part in the plan, but that doesn't really affect any of you...so I'm gonna keep it a secret!"

(A/N: Yes, (Y/N) can canonically falcon punch people. I hope this version of (Y/N) is powerful enough for you guys, even though this book won't consist of him one shotting people. However, this book will focus on the date a live spirits, the shonen big three, DxD (the alliance not the show), and whatever the fuck is up with Doctor V and Xemnas. Funny thing about that last one, it actually reveals how I actually started off coming up with this series a couple years ago. Best part of that is that NONE of the sources or even my OC's were the original reason.
