(Your POV)
Today was the big day, today was the day Rias would face off against Riser. So me and my peerage decided to watch, and by 'watching' I mean we illegally trespass onto Hell territory and threaten anyone who questioned what we were doing with extreme violence. Of course, it was all for the intention of watching Rias and Riser duke it out, and hopefully watch Rias wipe the floor with Riser. After all, a 20% critical hit rate is pretty high.

In any case, me and my peerage casual tread our way over the stands, with my having [Areadbhar] and [Lostvayne] in my grasp, since my spear does more damage against devils and demons. As me and my peerage made our way down the grand halls of the supposed arena the two devils will be fighting in. That was until I caught into a familiar scent in the air, which led to a closed doorway.

Not having much respect for hell, I kicked open the door to see Sona scream in fright after seeing me, causing me to give a light wave to her and Tsubaki. I signaled for my peerage to follow into the room, which looked to be a broadcasting room. There was a main computer, which Sona was sitting at, and many other screens around the room, all of which gave a different angle to the area.

"What's up fuckers!" I shouted into the room, kind of annoying Tsubaki and Sona as I did so. "Okay, I have no idea who Inosuke does this all the time. In all seriousness, hey you two!"

"(Y/N)?!" Sona asked, obviously terrified out of her mind thanks to the sudden intrusion. "What are you doing here?"

"Aside from resisting the urge to stab Riser multiple times, we came here to watch Rias' fight." I answered, noticing Sona's gaze kept on averting to Khun's brief case, Manbarondenna. "Hey, my eyes are up here."

"Sorry, I just noticed more magic energies in the room than meets the eye." Sona was now suspiciously looking at Manbarondenna, which she was about to go up to before I suddenly spun [Areadbhar]. "EEP!"

"Sona, please don't tell me you support this whole marriage agreement." I asked, bringing attention to my spear as I asked this, leaning closer to Sona's face. "Cause if so, that would make us enemies, and you know what we dragons do with our enemies..."

"N-No sir, we're 100% on your side!" Sona stuttered as he started to sweaty signaling that I should maybe lay off the intimidation.

"Good, because we need a place to watch the match!" I switched over to a gleeful attitude dismissing both of my weapons. "Hope you don't mind if we crash here!"

"O-Of course, stay as long as you'd like!" Sona breathed a huge sigh of relief as me and my peerage sat on a series of seats that were lined up behind the screens.

"Khun, pass the popcorn." I ordered my pawn, who rolled his eyes and reached into Manbarondenna to pull out a king sized popcorn bag before tossing it to me. "Thanks!"

After getting my popcorn, I got comfortable in my seat while Sora and Sujin sat on either side of me, both of whom were eyeing the popcorn. I sighed and let them have some, knowing full well how gluttonous they can be. As the two ate my pop-corn, the screens flash to life in front of me. They revealed they were fighting in an area unfamiliar to me.

There were two main buildings, one of which was labeled as 'old school' building and the other was called 'school building. Dividing the two buildings were a gym to the right, a track on the left, and a forest between the track and gym. There also looked to be two main bases, with Rias' being the old school building, and Riser's being the new school building.

There was a brief intermission, with Rias' peerage's familiars setting up traps in the forest to force Riser to use the other two pathways. Inside Rias' base, everyone in her peerage looked determined and battle ready. Kiba had his sword out, Koneko had a pair of gloves with cats on them, and Issei had his Sacred Gear already activated and boosting his power. This completely contradicted Riser's base, where no one looked to be taking this game seriously. Riser was simply staring at his peerage members while a tent forms in his...how do I hate this guy even more than I originally did?

In any case, the buzzer went off, signaling the rating game has officially begun. Rias sent Koneko and Issei through the gym Path, while keeping Asia, Akeno, and Kiba behind for defensive purposes. As Koneko and Tanjiro ran into the gym, they encountered four of Riser's pieces, whose names are Xuelan the rook, Mira, Ile, and Nel. Mira had some kind of bo staff in her hands, while the twins had...freakin chainsaws? Koneko took on Xuelan, starting the fight up with a Bo-Bup to get behind Xuelan and deliver a devastating kick, sending the girl away from her teammates.

"Hey, I taught her that!" Mori cheered excitedly as he started clapping his hands.

Shortly after, Issei used his gauntlet to deliver a punch to the ground, sending a shockwave throughout the ground that caused the three pawns to leap back to dodge the strike. Ile and Nel quickly recovered and revved up their chainsaws, then charging at Issei from both directions to try and cut him. Issei kept back to dodge the chainsaws, but Mira recovered and delivered a solid punch to Issei's stomach, sending him crashing into the wall.

Koneko on the other hand was dodging kick after kick from Xuelan, even delivering a couple solid blows from time to time. That was until Xuelan managed to deliver a flaming kick upwards, scorching Koneko's chin. However, Issei was nearby thanks to the blow from earlier and managed to deliver a right hook on Xuelan, sending her stumbling into Mira.

Keeping up the momentum, Koneko and Issei gracefully dodged the chainsaw swings from the twins, followed by Koneko delivering a power knee to the stomach to knock them out. As if on cue, Koneko and Issei left the gym, allowing Akeno to destroy it with the giant lightning ball she's been charging up since the beginning of Issei and Koneko's fight.

Now with the gym destroyed, four of Riser's pieces were now out of commission, but my attention was now more focused on the new player here, Yuebellena. Yuebellena appears to go by 'Bomb Queen' in the underworld, which is basically screaming that she uses explosive magic. With that in mind, Akeno and she exchanged a few words, followed by Koneko attempting to use Bo-Bup on Yuebellena, but the Queen simply delivered an explosion to the face.

Akeno and Yuebellena immediately began fighting with lightning and explosions respectively, while Issei rushed over to Koneko's side and attempted to carry her back to the base. However, Koneko told Issei off and forced Issei to run into the forest for some reason. As she did so, Akeno got hit with a massive explosion from Yuebellena, and got out shortly before Koneko did as well.

Issei was then thrown into a fight between Kiba and some of Riser's pieces. Kiba gracefully fended off each of the three pieces, who were Shuriya, Burent, and Marion. The three pieces kept on getting more cocky as time went on, but that was until Kiba sheathed his sword and walked away like he owned the pal e. Understandably, the three pieces were confused.

That was until all three pawns started moving frantically like they were being hit by a wooden sword, that is until Kiba was finally out of sight. Once Kiba was out of sight the three pawns collapsed in the ground, exhausted and confused before the announcer said they retired. That's when I realized Kiba used Moonlight sword style, the marionette technique that makes the opponent dance like puppets.

Kiba and Issei met each other at the track to take care of the final group, this time, there were both knights, both bishops, a rook, and two pawns. The knights were named Karlamine and Siris, Siris had a greatsword and Karlamine had a long sword. One of the bishops didn't look all that special, but the other bishop was Riser's little sister, Ravel. The rook also didn't look like much, but the pawns looked to be...cat girl twins?

I just watched as Karlamine tried using her longsword on Kiba, who blocked it with one hand before using the other to try and slash at her. Karlamine managed to block the slash, but she was caught off guard by Kiba's follow up slash. Issei on the other hand was handling the two girls he was facing off against perfectly fine, then I noticed that Issei had a glowing red energy sword with a matching shield...

"(Y/N), don't worry, that's his shinsu quality." Bam explained as he created an orb of water in his hands. "For example, mines a water orb I can use to control water. Issei's is not different, but his shinsu is sword and shield shaped."

After Bam's explanation, I continued watching the match to see Issei already managed to take out the cat girl twins, Ni and Li. Issei was now facing off against Mihae, the bishop no one notices that often. Mihae tried sending flares at Issei, but Issei's shield suddenly grew inside to absorb the energy before suddenly turning into a shield made of fire. Issei took advantage of this and charged at Mihae, igniting her clothes on fire as he boosted his power more and more.

Ravel tried sending two fireballs at Kiba, but the knight simply dodged with little effort after he knocked out Siris, shortly before blocking a swing from Karlamine. Kiba then kicked Karlamine's chest to knock her out. Kiba was on absolute roll until Isabelle, Riser's rook, held Kiba in place, allowing Ravel to land three solid fireballs onto Kiba, knocking him out of commission.

Ravel looked at Issei, who now glared at both she and Isabelle, seeing him as no threat for some reason. Ravel then proceeded to summon her wings and fly off, leaving Issei and Isabelle to fight on their own. Unfortunately for Isabelle, Issei had a secret weapon, a weapon he decided to use as he and the rook charged at each other. His secret weapon worked by Issei placing Ddraig on a piece of clothing, sending power through the fibers. The clothes fibers can't handle so much power, so they break.

In short, Issei's secret weapon is to strip his opponents.

Isabelle retired shortly after Issei destroyed his clothes, while Issei looked in the direction of the new school building and charged towards it.  On another screen, we saw that Rias and Asia were now making their way to Riser's base, while the king in question looked more annoyed than worried. Yuebellena also showed up to the room and started talking, but her little talk was cut off by Riser punching her cheek and forcing her to shut up.

On the roof, Rias, Issei, and Asia all managed to come face to face with Riser and Yuebellena. Rias was at a huge disadvantage in terms of power, but she can use Issei's Sacred Gear to boost her own power and/or Issei's shinsu quality to take care of enemy spells for her.

However, Riser used his fire magic to summon two flaming wings and charge at the trio, while Yuebellena sent explosions towards them. Issei got in front of them and expanded his shield to take the impact, which worked for a couple seconds. Sadly, Issei's shinsu seems to have a limit, since the shield quickly blew up in his face and sent him back.

Rias tried sending four explosive orbs at Riser, all of which Riser took dead on. There was smoke thanks to the explosion, and Rias got confident for a moment, but her hopes were dashed when Riser emerged from the smoke, seemingly unscathed. Riser then delivered a flaming uppercut to Asia, causing Issei to go berserk.

Issei was constantly boosting his power with Ddraig, somehow increasing the size of his sword. Issei tried slashing at Riser with the sword, but Riser dodged it only to be met with an uppercut from Issei. Yuebellena attempted to blow Issei up, but the pervert cut the spell in half and absorbed the magic energy to set his sword ablaze.

Issei constantly fought back Riser with all his might, while Asia managed to recover from the hit with the help of Rias. Rias sent four orbs of destruction at Yuebellena to get her out, but Riser took the hit once more to show of his healing factor.

This little cycle kept on going until I noticed Issei was running out of energy, literally, his shinsu sword was gone and his Sacred Gear stopped glowing. Riser saw this as an opportunity to strike, so he took the chance and grabbed Issei by the neck, holding him as he flew into the sky with his flaming wings. Riser then spoke to Rias about something, causing her to look conflicted before nodding.

Then the game was over, and I knew exactly what Riser did...

"That was underhanded, even by my standards." Khun commented as he looked over at me, noticing the frost I accidentally summoned around me. "(Y/N), are you alright?"

"No." I answered, noticing my breath was now a mist, then I became even more annoyed before standing up. "Guys, c'mon, it just so happens a certain chicken put me in a foul mood..."

(Timeskip, brought to you by (Y/N) using his crafting table to modify some items.)

(Third POV)

In the cathedral, it was a joyous day for everyone except for a certain group of individuals. Rias Gremory's peerage, all of whom were beyond pissed. Akeno was wearing a dark purple yukata, Koneko was wearing a soft yellow dress, Asia was wearing a soft blue dress, Kiba was wearing a suit, and Issei was reluctantly wearing dress clothes. All of them sat in the front row on Rias' side of the cathedral, glaring daggers into the shit-faced grin that belonged to Riser Phenex.

After a while of waiting, the large doors in the back open to reveal Rias, wearing a beautiful wedding dress that was dark red in color. Despite being the 'happiest' day of her life, Rias looked...dead. Her eyes lost all spark that once resides in them, her mouth hung open like a zombie, and her skin was even paler than usual.

Despite this obvious hints, Riser didn't take a hint and continued the ceremony as if Rias was fully willing to go through with all of this. The preacher then began going through with the tradition, with Issei desperately looking around for a way to save everyone. Issei gave up on the idea that you were coming, since it'll be illegal for you to be in hell in the first place. However, his search was cut off by Asia placing a hand on a shoulder while nearing an expression that said 'it's over.'

As the ceremony continued, there were bits of screaming to be heard in the distance but nothing that concerned Riser or the crowd in the slightest. The preacher kept on talking about the 'sacred nature' of weddings, making Issei scoff in annoyance. He kept zoning out until the preacher said the line Issei has been waiting for.

"Now, does anyone have any reason as to why these two should not be married?" The preacher asked the crowd, and Issei was about to shout but Koneko placed a hand over his mouth.

Issei could only watch in horror as his boss desperately looked around for someone to help her, but no voice dared to object to the will of two high ranking devils. That was until the massive door flew off their hinges and an arrow placed itself in the middle of the preacher's book. Everyone turned around to see no one other than your holding [Failnaught] and wearing a new attire.

"Yeah, I have multiple reasons, wanna hear them?"

(Your POV)

I was grateful I managed to arrive just in time, those guards were more of a speed bump to be honest. What I wasn't grateful for were all of the guards in this room suddenly running at me with their spears at the ready, so I summoned one of my newer weapons [Dawnbreaker]. Once the devils were close enough, I did a horizontal slash before dismissing the sword and walking to the altar.

The devils didn't realize it at first, but my slash managed to leave massive scars across their bodies. Given how the blade was also holy, I have my doubts that these guards will survive that. However, more devils decided it would be a good idea to try and attack me, but I didn't falter as I calmly walked up to the altar with Riser and Rias.

Before the devils could hit me, knights emerged from my shadow to block the hit, followed by Sung, Jihan, and Joe replacing the shadows and fighting back. Sung made no effort as kicking the first devil away, Jihan used mana arrows to sent the next devil flying, and Joe turned into a lion to maul the next devil. I can tell some more devils were about to intervene but the rest of my peerage showed up to force them to back down.

"So, Riser, dare to take what I said into consideration?" I asked the devil, who looked at me in shock and disbelief. "What's the matter, cat got your tongue?"

"You dare interrupt Riser's wedding for this?" Riser tried punching me with a flaming fist, but I summoned [Shield of the Just] and blocked the hit before it could hit me. "How dare you block a hit from Riser?!"

"That's how a fair fight works, you winged boar." I dismissed my shield before crossing my arms cockily. "Maybe it's because you've never had to work a day in your life! That would also explain your bird-brain!"

"Who invites you here?!" Riser asked, making me grin even wider. "What's so funny?"

"No one invited me here, I'm just here because someone close to me is about to get forced into a marriage they didn't want!" I laughed to myself as I caught a glimpse of Rias' eyes, which managed to regain the sparkle they once had. "In any case, now that I find her, we should be going now. C'mon Rias!"

"O-Okay!" Rias quickly grabbed my hand in a gleeful manner, causing me to gesture to her peerage to stand up, and we began our march to the doors before...

"Hold it." Some guy who looks like a genderbent Rias stopped us right before we reached the door, making me want to use my new breath style already. "Mister (L/N), do you have any idea what you're doing."

"Getting someone out of a bad situation." I admit, realizing that this guy and Rias have similar scents, meaning they must be related. "Another thing I can tell is that you need to update your laws, like what the hell? Selling off your sister as a bargaining piece to a pedophile, are you deranged?"

"(Y/N), I'm Sirzechs Lucifer, one of the four great satans?" The new,y introduced Sirzechs introduced himself to me, causing me to lose even more interest in Hell. "So I recommend you try to watch your tone."

"You look like a nice guy, so I'm just going to be honest with you." I groaned before pointing the tip of [Dawnbreaker] at Riser, who tried sneaking up behind me and Rias. "Don't use your sister as a fucking political bargaining tool!"

"(Y/N), get your temper under control, and just challenge Riser to a rating game!" Issei barked at me, which I would be mad about if he wasn't right.

"Fine." I closed my throat and faced Riser fully. "Riser Phenex, I, (Y/N) (L/N), challenge you to a rating game."

"Riser gladly accepts." Riser cockily accepts my challenge, most likely not even somewhat aware of at least half of my abilities. "On one condition."

"Why do I have the feeling he's about to say something even dumber than what Issei says on a daily basis." I asked myself before Issei punched my shoulder, which didn't even hurt thanks to my armor. "Shoot."

"Rias has to fight alongside Riser and peerage!" Riser commands, making my earlier statement true. "After all, it's the duty of a married couple to fight alongside each other, so it's natural that the Great Riser would want to see if Rias holds him back."

"That's dumb." I groaned in annoyance, while Rias gave me a nervous stare, like she knew something's about to happen.

"Very well then, (Y/N) (L/N) vs both Riser and Rias' peerage!" Sirzechs announced to everyone in the room, pissing me off further.

"You mother fu-" I couldn't finish my sentence because of a sudden flash of light that appeared beneath me and everyone else in the rating game.

I was temporarily blinded before my eyesight returned to me, revealing I was in the school house, I guess this school is my base. I looked around the room to see my peerage members, all of whom are ready to fight with their new equipment and/or skills. However, I knew there was a buffer time, so I decided to start placing down sentries and dispensers around the school. As I placed my machines down at random points, I looked at Sung, who stepped outside for a moment before saying his magic words.

"Arise." Sung said to himself, causing his shadow to cover the entire area and soldiers to emerge from it as the shadow covered the area, as his shadow soldiers emerged from his shadow, Sung looked at me and nodded.

"Alright, remember guys, we're showing all of hell what we're made of!" I turned to face my peerage, all of whom were standing at the ready. "In other words, no holding back!"

"So what are our orders?" Jihan asked with a smile, while he held his staff at the ready. "Hey, you're the king here."

"Very well then...Dawei, Mira, Mori, Ilpyo, Sujin, you five take the gym." I ordered the five martial artists, all of whom nodded in understanding. "You guys stay there until I give the order for you guys to move to Riser's position at the time."

"Sure thing, bossman." Mori saluted before dashing out of the old school building with the other four martial artists.

"Khun, Rak, you two are to guard this building." I explained as Khun nodded in understanding but Rak looked annoyed with his role. "Rak, you're supposed to stand on the roof and shoot your spear at any enemy you see, making air travel impossible for the enemy team."

"Good to know you can recognize greatness when you see it, King Turtle." Rak proudly cheered before walking out of the old school building, with me not really certain where he's going.

"Ethan, Sora, Dark, Seungchul, you four take the track." I order in a similar manner I did with Mori's team. "Like I said with Mori's team, stay on the defensive until I give the signal."

"Don't let us down!" Ethan requested before leading his party out the school and into the battlefield.

"Bam, Jihan, John, you three take to the air with your abilities." I said before focusing on John. "John, you copy Bam's blue disk ability and test it out before carrying out this order, understood."

"Yes sir. John joked as he followed Jihan out the door and the three began flying, then I noticed Rak scaling the building with his claws.

"As for Shiyeon, Endorsi, Sera, and Sung, you four will be on recon due to your speed and skills in martial arts." I gave the order, making the three girls nod while Khun summoned his lighthouses and began sending them out into the battlefield.

"What about you, you're gonna do something, right?"  Khun asked as he held his knife between his finger tips, toying with it as he talked.

"Of course I am." I answered before summoning [Lostvayne] and looking out the window and into the forest. "I'm just going to show Riser what a real storm is."
