(Your POV)
It was an average day in the ORC clubroom, only difference was that I was standing on top of a ladder with a couple lightbulbs in my hand. Like I promised, I was fixing up the lights in the ORC clubroom to make it easier to actually see. Asia, Issei, and myself have been stumbling over furniture and constantly stubbing our toes. Even with my immense pain tolerance and almost superhuman durability, I started to get annoyed with it.

"Hey Rias, can you hand me the wire cutters?" I reached down the ladder, where Rias stood with my toolbox on the coffee table. "I need to hook up the chandelier with an electrical system."

"Sure thing." Rias pulled out a pair of pliers and handed them to me, so I calmly climbed down the ladder and pulled out the wire cutters from my toolbox. "Aren't they the same thing?"

"No, you see wire cutters have these slots in them of varying sizes to make it easier to cut wires." I pointed out the various holes in the wire cutters. "I don't think you've taken a workshop class, so it's understandable you don't know what they are."

"Sorry about that." Rias apologized as I climbed back up the ladder and continued managing the wires. "Say, why do you know how to do all of this stuff? We don't have any workshop classes?"

"During extreme storms, it is not uncommon for the lighthouse to be torn apart, so it's up to me to fix it." I answered calmly as I lined the chandelier with gold painted wires, just so the wires blend in.

Rias and I were the only ones in the clubroom, due to everyone else having classes. I didn't worry too much about my classes because even if I didn't become a devil, I was going to manage the lighthouse all my life, so my education was pointless. Plus my grades were above average, and I can afford to take a couple days off. It was peaceful before I descended down the ladder, which Rias wrapped her arms around me from behind for some reason. The smell of roses filled my nose, which did seem to suit my master.

"Is there something you need?" I asked, I didn't want to seem rude or anything, but I was curious as to what she needed.

"(Y/N), promise me you'll always stand by my side." Rias' usual authority seemed to be absent today, now she sounded...scared for some reason. "Don't ask why, I just need it."

"Even if I am recruited into someone else's peerage, I swear on my soul I will always protect you and stand by your side." I reassured Rias before gently grabbing her hand and kissing her ring finger. "You have given me a purpose, and for that I am eternally grateful."

"Thank you." Rias still did let go, but judging from the fact that she was still trembling, she was still scared. "Thank you for everything."

"Why are you getting all sentimental?"

"Nothing, don't worry about it."

(Timeskip, brought to you by (Y/N) internally dancing at the sight of the lights working)

A couple hours later, everyone was back inside the ORC clubroom and examining my handiwork. Now the clubroom was bright enough to see in, and everyone noticed it. I had the ladder put back in the storage room while my toolbox was in the corner of the room with Genbu, my anchor and shield. Issei and I were playing a mobile game he recommended on the couch, and he was giving me a guide as to how to play. Asia was watching the two of us play as she sat between us, Koneko glared at Issei for existing, Kiba was checking out Genbu, and Akeno was playing against Rias in chess.

"Oh shit, pink killed yellow!" Issei exclaims before my screen changes to a discussing mode. "You know the drill (Y/N)!"

"I vote for pink?" I guessed, making Issei nod as he began typing into the chat. "Okay."

"Is it me, or is it unnaturally peaceful today?" Kiba asked out loud, which is a sure sign something is about to happen.

Some more time passed, with Issei and I continuing playing the game where we play as beans in spacesuits, but then something changes. The electrical system I just fixed began flickering on and off, causing Asia to cling to me, but Rias didn't seem too surprised, but she did seem concerned. A pillar of flames erupted in the middle of the room, which caught Issei so off guard he almost fell off the couch. Since he's my friend, I grabbed him by the collar and helped him back onto the couch. The flames left a bunch of soot on the roof, so I sighed and walked over to a nearby storage closet so whoever actually has to clean the place doesn't have to take care of the roof.

Does the school janitor even take care of this building?

Either way the flames dispersed to reveal a man with blonde hair, a cocky smile and smells of both ash and cologne. I noticed he had fifteen people standing at his side, and I know I'm not the best at reading people, but none of them look too happy to be here. I noticed the man walking towards Rias whilst my master stood up from her chair to face the man.

"Rias, my dear..." The man greeted all too casually, but I didn't like these kinds of people, they were a living embodiment of the Dunning-Krueger effect. "It has been far too long."

"Riser, what are you doing here?" Rias asked in a stern voice whilst glaring at the newly dubbed Riser strut to my master like a chicken.

"Riser himself has come here to inform you that the day of our wedding has been moved to be much sooner than any of us expected." Riser bragged, so this is what my master feared. "The wedding will occur soon, so now you can quit your goals and just be my bride."

I could see my master trembling in fear, anger, and disgust of the man before her, but she held it in for the sake of her dignity. Riser about to touch my master, and she flinched from a touch that was never going to come near her. I used the broomstick of the broom I got from the storage closet to knock the devil's hand away. Riser took noticeable offense to this, but I didn't care, I stepped in front of Lady Rias and glared at Riser.

"Who the hell is this?" Riser asked as he examined me, his attention focusing on the parka around my waist. "Of all the beings you could have recruited, you recruit a glorified sea dog?"

"Riser, this is (Y/N), my rook." Rias introduced me to Riser as I held a broomstick in one hand and grabbed a glass bottle of rubbing alcohol from the coffee table. "By the way, I would appreciate it if you didn't call him a dog."

"Well if this (Y/N) fellow didn't stand in my way, then maybe I wouldn't have too." Riser acts like he hurt my feelings or something, but his words mean nothing, I am nothing, end of story.

"You shall not come within five feet of Lady Rias, due to you clearly making her uncomfortable." I was taller than Riser, so I tilted my head upwards to look down at him. "Do I make myself clear."

"Look here, you dog, stand out of my way." Riser placed a hand on shoulder and it began burning, even to the point where I could see smoke coming from the injury, but I didn't even flinch.

"I am not limiting your ability to speak, but I am limiting physical contact." I gripped the bottle by the handle and was 100% ready to smash this guy's face in, but the blood would most likely be put on someone else's hands.

"Brother, just sit down." A small, blonde haired girl sat on the same couch as Issei, causing my perverted friend to walk away, not wanting to get involved.

"Fine." Riser removed his hand from my shoulder, causing a hand-shaped burn and hole in my shirt to be visible to everyone in the room, but I remained perfectly calm.

Lady Rias and I sat side by side on the couch across from Riser, with me flipping through the spellbook I got the other day and Rias glaring at Riser. Asia was behind me, healing my scar, which I was incredibly thankful for. Akeno also stood behind us, but she stood closer to Rias. Kiba and Koneko stood on either side of us while Issei gawked at my injury.

"Dude, you just burn a hole through my best friend?!" Issei was pissed, pissed enough to summon his gauntlet. "I don't care if you're a high class devil-"

"Issei, relax, my pain tolerance managed to neutralize the pain." I lied, the burn did hurt, but as the Ultimate Shield, I've become a pro at ignoring pain.

"So Riser, what do you mean by 'the wedding will come soon' ordeal?" Rias asked, and it was already obvious what the chicken meant.

"Simple, Riser arranged for the wedding to occur the moment you turn 18." Riser boasted, which is a clear red flag if I ever saw one. "The wedding will occur in a couple of hours."

"Did you ask Lady Rias for her input?" I asked as I noticed Rias went pale from fear. "Evidently not...."

"Of course Riser didn't, what kind of woman wouldn't want to marry Riser?" Riser looks boastful, and for once, I felt my body become filled with an emotion I was unfamiliar to.

Murderous rage.

I used the bottle and quickly bashed the base of it against Riser's head, letting shards of glass fly. With the now broken bottle, I was about to jab it in Riser's face, hoping to send him to the nearest hospital. However, an unfamiliar hand stopped me. I still surpassed them in raw strength, but they managed to judo flip me onto the ground in a fraction of a second. I got a good glimpse of who was flipping me over, their gray hair flowed gently as she tossed me over. With a loud thud, I hit the ground. The broken bottle I was holding was in my grip until I hit the ground, which I was then forced to release it.

"Forgive me (Y/N), but you are not allowed to harm Riser Phenex." The woman informed me, but I didn't care, I was ready to pull out my desert eagle, but Akeno stopped me.

(I know at least one of you guys love this character, but she's not gonna be in the harem. She's married so she's off limits. Don't like it? Write your own story, it's fun and I'll help you get started)

"(Y/N), relax, you can't beat Grayfia right now." Akeno whispered as she held a hand out for me, so I grabbed onto it and she helped me up. "Besides, trying to kill a noble is a bad idea."

"Forgive me, I let my rage get the better of me." I apologized, but I would much rather die than apologize to Riser, he just gives off the aura of cockiness like a chicken.

"It's fine, but you must remain calm." Akeno encouraged me as she rubbed her hand on my shoulder as we watched as Rias regained her composure and demanded an explanation.

"The deal was for the wedding to occur when I graduate, so why the sudden change, Grayfia?" Rias asked as we all glared at the new woman, if she hasn't shown up, we wouldn't be in this mess anymore.

"Well Lord Phenex ordered we change the date at which Rias could get married to be as soon as possible." Grayfia informed us, and I used the broom I set down earlier to sweep up the shards of glass.

"You're lucky that Riser is forgiving." Riser boasted, somehow uninjured, and I was ready to summon my familiar to kill this man, but if Lady Rias orders for it, then I shall not murder him. "You seem confused, the Phenex family is superior because of their ability to use fire magic and have healing factors. I suppose an ignorant dog like you wouldn't know any better."

"Leave my rook out of this, this business is between the two of us." Rias defended me, causing Riser to turn his attention back to her, giving me an opportunity to walk to the other side of the room.

"Don't worry, Riser won't harm any more of your pieces, but only if you come along quietly." Riser pushed his luck, so I looked around at Riser's little group, trying to find someone perfect for what I have in mind.

"This is bullshit, you can't just make a girl fall in love, all perverts know that the best kind of hentai is consensual!" Issei made a valid point in the first half, and confused me in the second half.

"Is there no way to settle this in a better way, one that could benefit both parties?" Kiba was always the voice of reason, but now even he sounds nervous.

"Whatever do you mean?" Riser quested the Knight piece with a cocky grin. "Marrying Riser benefits everyone, the Devils, Rias, and especially Riser.

"Are you sure about that, you're just as bad as Issei, if not worse." Koneko commented, causing Riser's temper to increase, which was obvious by the sight of him summoning a fireball in his hand.

"You little runt, I'll marry Rias no matter what you say." Riser says as he stood up to confront Koneko, but he was stopped short when he heard the safety flick off on a gun.

He turned his attention to one of his pieces, which I'm going to assume is the queen piece based off the way she was dressed. I currently held her close to me with wrapping my arm gently around her neck since I don't wish to hurt a bystander, but I made it look like I was keeping her in place. What's more, I had my Desert Eagle's barrel pressed against her head.

"Play along or the situation becomes much more dire." I whispered into the woman's ear before focusing on Riser. "Riser, I command that you give Lady Rias a fair chance."

"That's 'Lord Riser' to you, you savage dog!" Riser barked back, but I shot a bullet right past his cheek bone.

"I refuse to address someone in such ways unless they prove to me they are worth it, a shield must have standards on who they serve afterall." I returned the barrel of the gun to the queen piece's head. "As for me, I am nothing more than a disposable shield. I will dirty myself in sin so my allies can live clean in virtue. So this is an order, give Lady Rias a fair chance in rejecting this marriage or your pieces die."

"As far as Riser's concerned, you only have Yuebellena?" Riser mentions, so I began chanting.

"Lord of the north, where the white bears roar, grant me shackles and chains to bound my foes." I chanted as the temperature around me and Riser's peerage began to drop. "Frozen Man's Shackles."

"Looks like he's got you beat, Lord Riser." Grayfia examines as chains and collars appear around all the remaining peerage members who no one seems to care about, but I try to make sure not to hurt them.

"What do you mean by that?" Riser walked to one of his pieces and saw that his flames did not melt the ice, shocking the man.

"Frozen Man's Shackles is a spell developed by the Fae of the North, specifically designed to counter magic users by absorbing the magic exposed to it." Grayfia seemed well educated in spells, compared to me, who just learned this spell two minutes ago. "I recommend you challenge Lady Rias to a rating game."

"Fine, Riser will give you ten days to prepare!" Riser didn't sound happy, but he agreed to it, allowing me to turn the ice shackles into snowflakes and removing the gun from Yuebellena's head.

"Glad to hear it, try to be more open minded next time you hold negotiations." Rias advised as Riser scoffed and walked back towards his peerage.

"Whatever, Riser will defeat everyone anyways." Riser commented, but Issei stepped up to say something that wasn't perverted.

"Oh sure, you and your group of extras are going to beat the mighty Oppai Dragon Emperor, some guy who is definitely immortal, the world's most dangerous noodle, a Gremory, a sadist, the definition of a prince, a cinnamon roll, and the definition of tiny but mighty." Issei gestured to all of us as he said that, with the exception being Jörmungandr, who wasn't ever here.

After Riser left in another pillar of flames, I finally let my anxiety kick in at the realization of what I've done. I just assaulted a noble and held hostages of innocent bystanders. Despite my facial expression not really changing, tears began to comically leak out of my eyes. I had a feeling my master would have scolded me, but instead, she helped me up.

"That was pretty foolish of you, what if Riser killed you right then and there." Rias scolded me, causing me to start apologizing profusely. "However, I'm glad that you were willing to go to such lengths to help me."

"I only did what I did because everyone here were the first people not to give up on me." I wiped the comical tears away before returning to my usual stoic facial expression.

"Hey, you kind of saved my ass that one time at the mall, so I owe you big time." Issei wrapped an arm around my shoulder. "Plus it's thanks to you I didn't die...so I say we're friends now."

"So what now, Lady Rias?" I asked the girl, who looked confused. "I may be durable, but I'm far from invincible, so we need to train ourselves in order to stand a chance against them."

"You're right, we'll head over to my family's vacation house for training." Rias walked to her desk and pulled out a piece of paper, then she got a pen to begin writing on it. "This paper has the address on it, we'll be there on Saturday to begin training. Akeno, let the school know we'll be absent on those days. Everyone else, prepare yourselves."

"By the way, Riser radiated small dick energy." Issei commented out of nowhere.

"Agreed."

(A/N: Here's a little Easter egg: the reason why everyone calls (Y/N) 'dog' is actually a reference to the fact that he was originally going to be called 'The Ultimate Junkyard Dog' instead of 'The Ultimate Shield'. Also, I just realized that the reason why 'Ddraig' is called the welsh dragon, it because he's the dragon on the Welsh flag, which is honestly pretty underwhelming. Though I feel like making Issei a demigod of Zeus would fix that problem. Hey, every fuckboy needs a fuckfather.
