(Your POV)

I started the fight off with a slash with [Lostvayne], which Riser blocked before I summoned [Soda Popper] from my inventory and shot Riser point blank in the chest. Luckily, [Ebony Mail]'s ability kicked in and covered me in a black aura, releasing poison all around me and poisoning Riser. Riser looked noticeably shocked by this, and I grinned as I pulled the trigger. This sent Riser back with a hole in his chest, which closed up quickly to reveal he had a healing factor. I then used [Observe] on him to see his stats and better form a plan.

I quickly dismissed the pop-up to react to a sudden fireball heading at me, which I summoned [Spellbreaker] to absorb. I stood firm as I held the shield directly in front of me, watching as the shield dispels the spell. This pissed Riser off even more and caused me to grin. I remembered that Riser beat me in all physical stats, as well as charisma, so it looks like I'll have to outwit him with my overwhelming inventory and new surprises.

"Use skill: [Rain Breathing, second form: Sea Bishop]!" I used the skill on both [Lostvayne] and [Soda Popper], making them glow a (f/c) hue and start attacking Riser as if someone was using them.

[Lostvayne] slashed at Riser's forehead, followed by me summoning [Trident of the Oracle] and [Areadbhar]. I lunged at Riser to strike a Riser with my trident, followed by me slashing at Riser's legs with [Areadbhar]. Riser got struck in the chest with [Trident of the Oracle], but he somehow kept up to dodge [Areadbhar] before sending a fireball at my face.

I didn't have enough time to dodge the blast, so a fireball hit me dead in the face and sent me back a bit. [Soda Popper] then clicked behind Riser and shot him dead in the face. Riser then grabbed the gun to melt it, but I quickly dismissed both of the weapons I used my breathing style on.

"Use skills: [Rain Breathing, Third form: Nessie] and [Rain Breathing, Fourth Form: Iku Tursu]." I then stomped my foot, summoning thirty different weapons in the earth, hidden from Riser as the man in question charged at me.

As I summoned the weapons below me, I drew both of my spears back as water began covering the tips, similar to how water covers my sword when I use [Water Breathing]. I then waited until Riser was directly in front of me before launching me spears at his wings, forcing them through and sending Riser over the area with weapons underneath it. I then snapped my fingers and all of the weapons shot up from the ground, impaling Riser and sending him upwards.

I dismissed all of these weapons in favor of [Failanught] taking aim at Riser, who was now flying in the air with his wings, which were regenerating. Riser then took flight at me to land a punch as he coated his hand in flames. I kept on firing, but every arrow I shot at Riser was dodged until Riser's fist connected with my cheek. Instead of retaliating, I simply smirked.

"Why're you smiling, punk?" Riser asked, completely unaware of the three arrows I'm drawing.

"[Rain Breathing, Sixth form: Krakinos]." I then turned into a (f/c) light and warped behind Riser, while leaving behind [Aymr] to rotate violently in front of Riser like a wheel.

After rematerializing myself, I shot the three arrows at Riser and kicked him into the still rotating axe. Riser quickly stood back up to deliver a flaming roundhouse kick to my side, which I didn't have time to react to. Riser landed a kick to my side, but I took advantage of this kick and dismissed my two weapons before grabbing onto Riser's leg and holding him in place.

"[Rain Breathing, Tenth Form: Scylla]." I then summoned fifteen melee weapons around me, all of which began rotating around me like a buzzsaw and gave Riser a deep slash to the stomach.

Riser jumped back to avoid getting cut more, while his wounds started healing rapidly and I summoned [Mace of Molag Bal] in one hand and [Dawnbreaker] in the other. I quickly used my mace's weight to spin rapidly as I leapt above Riser, forcing the devil into a defensive position to block my rapid strikes. I then attempted to slash at Riser with [Dawnbreaker], but the noble quickly sent a fireball to my chest.

Luckily, my quirk [Black Dragon] activated, followed by me using [Lord of the Sea] to make rain fall from the sky. The rain was intense enough to block out most people's sight, with the only exception to that rule being people who live underwater. I then summoned [Taiyojoo] and [Tsukihime] before activating their shikai forms, followed by me summoning [Joker] to use his 'hopscotch' ability.

After looking at the newly formed lines across the ground and hearing multiple 'cracks' coming from Riser's position, I gracefully ran over to the location, not stepping on any lines in the process. Riser was having trouble seeing and finding me, and the newly added lines weren't helping Riser's chances. Every time he stepped on a line, his back contorted into a painful position before his healing factor kicked in and healed him.

I quickly used [Shiro Tsukihime] to temporarily leap from the cover of the rain to deliver two slashes before leaping back. After leaping back, I aimed my [Slinger] at Riser and fired an [Ice Pod] I got when Khun and Endorsi got their equipment repaired. After firing the shot, Riser's right shoulder became encoated In ice as I quickly ran around him to stay stealthy.

"That's it, if you wanna play that game, I'll play it too." Riser then used his wings which somehow didn't extinguish under all the heavy rain, before charging up a giant orb of fire that looked like a miniature version of the sun.

"[Breath of Rain, Eighth Form: Kelpie]." Was my response, followed by me pointing the tip of [Shiro Tsukihime] at Riser as all of my weapons appeared behind me and launched themselves at Riser.

Riser was forced to dodge all of my weapons, dispelling his original spell when he did so. After the attack, all of my weapons vanished in (f/c) flashes before I summoned [Bow of the Clever] in my hand with [Kuro Taiyojoo] and began firing black fire arrows at Riser. The noble didn't seem to activate his ability to control the flames, maybe it has to do with the fact these flames are similar to the Uchiha clan's amaterasu.

Using this to my advantage, I kept on the onslaught until Riser pinned down my location and swooped down like a hawk. I would have my Breathing style once more, but it has a five second recharge, just to prevent my breathing from becoming too hectic. So I had to watch as Riser grabbed my throat, and dragged me through the ground as he flew into the sky before throwing me into the ground. This created a huge crater where I landed, and caused me to cough up blood. I suddenly felt weaker, so I opened up my [Stats].

I then looked at Riser as he started charging up his spell once more, somehow making it larger in the process. I then proceeded to close my eyes in acceptance of the hit, followed by Riser throwing the giant orb of fire at me. As the giant flaming ball came at me, a shadow appeared in front of me and blocked the hit. Just as planned...

Despite everything going according to plan, Riser began laughing cockily as he flew onto the ground, with the rain unfaltering. Riser then began shouting insults at me, targeting my 'lower antenna' size of all things. After that, he then proceeded to list off all of the things he was going to do to Rias once he married her. Unfortunately for him, he couldn't see past the smoke to see me standing with my stand and persona, with me using [Rain Breathing, Seventeenth Form: Njordic Fortress] to heal myself. Riser kept on talking as smoke started to clear, then I saw my moment come.

"Your next line is: 'Riser expected no more from a worthless serpent!'"

"Riser expected no more from a worthless serpent!" Riser boasted before realizing I was still standing, turning around to see me and my newly acquired persona [Adversity]. "What the-?! How did-?!"

Skills:
Worthy Foes are not Forgotten: Adversity can take the shape and form of any boss you have fought against that gave you trouble, taking all their stats as well. If there was a tough boss battle with more than 1 boss, then Adversity will multiply itself to fit that description. However, every transformation also makes Adversity weak to whatever that character would be weak to. Also, if Adversity dies in a form, Adversity can't use that form again until a week passes.

"Let me dumb it down for ya, my persona's ability is to take the form and abilities of video game bosses I've defeated." I explained as [Adversity] changed from Senator Armstrong to Sans. "Face it bud, you're outclassed."

"I'll kill you!" Riser was immediately thrown into a bloodthirsty rage as he charged at me.

Luckily, [Adversity] activated Sans' ability of telekinesis and covered Riser in a blue aura, followed by my persona sending Riser into the air and me shooting at Riser with [Failnaught]. Riser was recovering his health at a rapid pace, even with the divine enchantment on [Failnaught]. Before he could reach me, I turned myself into a tiny (f/c) heart by using [Soul Form] and flew around Riser before turning back to normal. Shortly after, I activated a combat art named [Never Miss].

I then summoned [Hitman's Heatmaker] and tossed it into the air, followed by me summoning [Mehrunes' Razor] and implanting it into Riser's chest. I then swung around to deliver an elbow to the back of the head, shortly before pulling out [Mehrunes' Razor] and using [Slinger] to fire an ice pod into Riser's chest. Then my sniper started falling to the ground, so I can sling it over my shoulder and pull the trigger. The bullet hit Riser dead on in the head, forcing him to collapse as his healing factor struggled to keep up.

Short after shooting him, I dismissed all of my weapons except for my zanpakutos to summon [Arthur]...why does he have those box things around his name? Anyways, Arthur understood what I needed and activated his golden fairy wings as his sword started glowing a bright yellow color as he flew at Riser. Arthur cut Riser's cheek, causing it to start burning for a while before closing up.

Unfortunately for Riser, Joker and Adversity like playing these games as well. The noble in question was completely caught off guard by the sudden appearance of Gaster Blasters above him, as well as my stand leaping from his shadow and stabbing him through the chest. I then proceeded to use [Rain Breathing, Eleventh Form: Raijinto] by drawing [Shiro Tsukihime] back, then summoning [Sword of the Father] and [Sword of the Creator] on the other sides of Riser.

I then slashed at Riser, leaving a trail of lightning behind me like I've seen I Zenitsu do when he uses his breath style. I then grabbed the [Sword of the Creator] to begin the cycle again but now heading to the [Sword of the Father]. After slashing at Riser with all three blades, I dismissed two of the swords and moved out of the way of Arthur's pierce at Riser's ear.

Arthur managed to cut off a chunk of Riser's ear, while Joker laughed maniacally as he tried slashing at Riser, but the noble caught the blade and delivered a flaming uppercut to my stand, damaging me as well. Despite this, Adversity was still in it's Sans mode as it summoned bones to stick out of the ground and to act as spikes. I used these bones to avoid Joker's line and deliver a slash to Riser's eye, but the Phenex dodged and retaliated with a flaming kick, which I grabbed with [Kuro Taiyojoo].

The gauntlet managed to engulf Riser's shoe into black flames, but Riser was actually capable of using his head now and threw off his shoe to avoid touching the black flames. Unfortunately, he touched a line made by Joker, resulting in his back quickly bending in an unnatural way. I then summoned [Uriel and Ariel] in front of [Adversity] allowing my persona to grab them and give me a nod. Arthur took advantage of Riser's vulnerable position though, slashing at his left arm like a hacksaw.

Riser got annoyed with my familiar and set his entire arm on for to fend off the mouse before sending a ball of fire at my persona, who quickly pointed both pistols at Riser. [Uriel] absorbed the flames as they were about to hit my persona, followed by [Ariel] shooting a powerful gust of ice at Riser, so the Phenex responded by summoning a flaming pillar in front of him.

"Use skill: [Rain Breathing, Eighteenth Form: Dance of the Four Gods]!" I tossed [Shiro Tsukihime] to Joker, allowing the stand to use my sword as I summoned [Failnaught] to begin my little dance.

I drew the bowstring of [Failnaught] back and took aim as the arrow became covered in a black aura, signaling the [Falling Star of the Black Turtle] is beginning. I let the arrow fly and hit Riser in the forehead, knocking him back into Joker, who used both of the swords and cut Riser's arms off. I then switched the bow out for [Aymr], followed by my warping in front of Riser with my axe above me before grazing his face as I slashed downwards. Following my slash, a pillar of flames and (f/c) energy called [Raging Storm of the Vermillion Phoenix] emerged from the ground like a pillar, engulfing Riser in the process.

Naturally, Riser tried to punch me, but I dodged the blow as I switched [Aymr] out for [Areadbhar] and began the next step. I activated [Atrocity of the White Tiger], which resulted in my rapidly moving to jab Riser in the neck, shoulder, leg, groin, and arms before finishing it all off with a slash to the side, sending Riser to Arthur, who slashed the devil back to me as I switched [Areadbhar] for the [Sword of the Creator].

I drew the sword back as Riser slowly recovered from his initial shock and ran at me, both of his hands were on fire. I stood still until Riser was about to deliver a left hook to my cheek, but I quickly slashed the sword to activate the final part of this dance, [Sublime Heaven of the Blue Dragon]. This resulted in a powerful shockwave coming from the slash as winds blew at Riser, strong enough to tear out the trees behind him. However, the slash also managed to leave a nasty gash on Riser's chest. This scar forced Riser to the ground while me, Arthur, and Joker pointed our swords at him.

"Give up Riser, you've lost." I said in a cold voice, making sure the tip of my sword was pointed at Riser's throat.

"Shut up, serpent!" Riser shouted before he pulled out some sort of pill from his pocket, which he swallowed in a moment. "Never underestimate Riser!"

In response to eating the pill, all of his injuries seemingly healed and he started to become covered in flames. The three of us were forced to leap back as Riser started letting loose screams of agony as his flaming silhouette reached out for me, desperate for someone to save him from his own mistake. That was until his silhouette stopped being human, the flames slowly took the form of a bird, leaving no sign of the former devil.

After seeing this, the phoenix quickly spread its wings to send a wave of fire at us, forcing my familiar, stand, and persona behind me as I summoned [Spellbreaker] to absorb the flames, but these flames were far more powerful than anything Riser could send at me. So I ordered for Joker to change the game to Duck on a Rock, with Riser being the duck. Not only that, I made Adversity change from Sans to Leviathan from FFXV, which is a giant serpent.

Adversity's new form summoned an ocean along with it, along with heavier rains that sizzled off of Riser's feathers. As for the Duck on a Rock game, it works by someone or something being the 'duck', and at least one person needs to be the 'guard' to guard this duck. While everyone else simply shoots the duck with rocks, kids are messed up. In any case, I caught [Shiro Tsukihime] as Joker tossed the sword back to me, followed by me dismissing [Uriel and Ariel].

I then snapped my fingers, causing nothing to happen until the sound of heavy machinery came from the forest. Riser turned his attention to the forest to see an army of robots were now opening fire on him with their guns. What? I didn't sit in that forest for nothing you know. I then pointed the tip of my blade upwards to the sky while Riser fought against Adversity, then I activated a skill.

"[Rain Breathing, Twentieth Form: Tialoc Rains]!" I shouted as a storm cloud appeared above Riser, followed by all of my weapons slowly emerging from the clouds and staying put.

That was until I gave the signal, which is me spinning [Shiro Tsukihime] before planting the Blade into the ground. After I did that, all of my weapons shot from the clouds like dangerous rain drops. Adversity also moved out of the way to avoid getting hit by the weapons, but Riser was too busy dodging bullets, missiles, and grenades from my robots. This resulted in all of my weapons tearing through Riser's body and grounding him.

Despite all of my weapons going through him and now standing on their own in the ground, Riser still stood tall, ready to fight. I felt pity on the man, which is stupid given my position, but have always felt pity for my opponents. Must be a side effect of Tanjiro's teachings.

"[Rain Breathing, Twentyfirst Form: Ryujin Tempest, Grand Hurricane]!" I shouted, causing all of my weapons to come covered in water, including [Shiro Tsukihime].

As Joker, Arthur, Adversity, and my robot soldiers all attacked Riser, I quickly slashed at Riser's chest with my sword before letting go and grabbing another weapon to begin the cycle. I lodged each and every weapon into Riser's body as I attacked, with the only exceptions being the ranged weapons, which I simply fired until I ran out of ammo.

I kept up this process until every single one of my weapons were either lodged onto Riser or out of ammo, but I still had [Lostvayne] in the same hand as [Kuro Taiyojoo], covering the sword in black flames. I then slashed at Riser one final time, causing all of the lodged weapons to fly through him and start rotating around him like a tornado. The speed of the tornado created a water tornado around me and Riser, while the other quickly fled to escape the danger of this breath style.

Unfortunately for Riser, his new form made him a much larger target as all of my ranged weapons aimed themselves at Riser and began firing mana bullets with a water enchantment on them. They kept on firing until Riser was on the brink of collapse, but the onslaught didn't stop. Instead, all of my melee weapons pointed themselves at Riser and began spinning rapidly like drills. After all of my melee weapons were spinning, they became covered in water and flung themselves at Riser all at once.

All the weapons exploded into a giant burst of water upon contacts but that didn't stop them from flying through his vital organs all at once, tearing him apart and forcing the phoenix onto the ground. Luckily, Riser started to turn back to normal, but his injuries still remained and left Riser unconscious. I walked up to him with [Lostvayne] and was about to finish him off, but a certain someone got in the way...

"Stop!" Screamed a voice as she flew directly between me and Riser, with her arms outstretched and determined expression on her face. "Please don't kill my brother!"

"Sorry about her." John apologized as he flew at Ravel, but I stopped him by raising my hand and lowering it. "Huh?"

"I admire Ravel's courage, so I have no choice but to listen to her request." I dismissed all of my weapons and turned around to begin walking away, leaving the two people in shock.

"Really?!" Ravel asked in shock, obviously surprised I spared her brother.

"That was...surprisingly mature of you." John commented on my actions, before I gained a grin on my face.

Despite saying I wasn't going to kill Riser, I was still a man of my word. So I warped above Riser with [Aymr] raised above my head, forcing Ravel and John to watch in horror as I brought the axe down on Riser. Of course, they were more concerned with where I hit Riser. So long story short, I struck Riser's little chicken full force with a divine axe made by goddess bones. After completely destroying Riser's lower head, I dismissed my axe once more and walked away.

"There's the chaotic dumbass we know."

(Timeskip, brought to you by (Y/N) pressing F)

After my fight with Riser, me and my peerage were all teleported back to the cathedral to be met with Sirzechs and an older version of Sirzechs who reminds me of Sephiroth for some reason. In any case, I looked around the room to see Rias' entire peerage and Riser's were 100% okay, but I didn't see their kings anywhere. That was until a red blur wrapped their arms around me from behind, that I grabbed the hands and gave them a soft squeeze for reassurance.

"(Y/N) (L/N), you managed to save my daughter from marrying Riser Phenex, congratulations." The red haired Sephiroth congratulated me while the three peerages clapped. "As a reward, just state your most craved desire and all of hell will make it come true."

"You know, I wouldn't be here if you guys adopted a reasonable way of forming alliances and getting stronger." I stated as Rias unraveled her arms around me and stood beside me, with her smile beaming on her face. "So how about NOT doing the whole marriage thing, unless both parties are 100% okay with it."

"Is that all?" Sirzechs asked, obviously surprised by my request. "You're asking us to change the way we do things in hell?"

"Did I stutter?" I responded in the TF2 soldier's voice, making everyone in the room sweatdrop. "Also, where's Riser? He in his room crying like a little bi-"

"No, he's under arrest for using some kind of drug during your fight." Sirzechs cut me off with a sweatdrop as he gestured towards Riser's peerage. "So, since he's in prison, his peerage is-"

"Going back to living their normal lives?" Ethan guessed for fun, with a grin on his face.

"Opening an underworld Pizza Hut?" Sora guessed, obviously hungry from all the fighting.

"No, they're going to be (Y/N)'s peerage-" Sirzechs announces before I cut him off with me clearing my throat obnoxiously.

"I appreciate the offer, but I already have a peerage." I gestured to my peerage that stood behind me, all of whom gave a skill wave, or simply flipped Sirzechs off if they were Khun or John. "Plus, I feel kind of bad for these girls, since devils tend to have slaves. So my recommendation would be to let them do whatever they want."

"That's not how this works..." Sirzechs explained before I summoned [Areadbhar] and slammed the blunt side on the ground.

"It is now!" I shouted in Bakugo's voice before turning my attention to Riser's former peerage. "As for you girls, you're free to live in the estate with the rest of us, but you're only joining my team if you want to, got it?"

"I'm in." Riser's former queen, Yuebellena stepped up with Ravel following close behind. "I want to fight under a different king."

"You spared my brother, so you get the privilege of having me on your team!" Ravel puffed as she crossed her arms and looked away, embarrassed about something.

"Okay, if you two are certain, select 'yes'." I ordered the two girls as I summoned two pop-ups in front of them for confirmation, both of whom selected 'yes' before pieces appeared above their heads. "Well, it looks like Yuebellena is a bishop and Ravel is a pawn."

"That's it?" Yuebellena asks, surprised that the process didn't take so long. "You're not going to have your way with me?"

"Geez, you're making me regret NOT killing Riser." I groaned as I started walking out of the cathedral, with my peerage following closely behind. "C'mon you two, you're a part of our little group of idiots, so you'd better get used to us!"

"Yes, Master~" Yuebellena cheerfully complied as she walked over to my side, with Ravel following close behind.

"You heard the man, c'mon girls!" Ravel turned her attention over to the rest of Riser's peerages who followed close behind my own.

With all of that said, the three peerages and two kings walked out of the cathedral and into the streets of well. Surprisingly, there was a giant magic circle in the middle of it that looked to be of Japanese origin. This magic circle was one used by my clan when we need to go to hell without dying, but right now I guess all of us are now going to get back to the clan house. Everything was at peace now, for this was the final chapter of this book...

"You are aware we're doing a beach chapter right after this one, right?" Sung asked, completely ruining the mood I was trying to set.

"DAMNIT!"

(A/N: Ya'll wanna know something funny? My waifu isn't anywhere in any of these series! Sure, the MC was close to Rias, but that's because I thought it would be funny if a devil an demigod were to get along so well. By the way, yes the next chapter will be a beach chapter. Why? Cause the MC is an ocean demigod who needs a break!
