(Y/N)'s POV

That night was tense for me...Issei told everyone about Asia.

"You had to open your damn mouth, brother." I hissed in anger at Issei, who looked at me with guilty on his face.

"Never go near the church again." Buchou scolded me. "The church is enemy territory. Just stepping into it can cause a rift between the Devils and God. Since you went there as an act of kindness they left you alone, but the Angels are always on the lookout. Normally you'd been hit with a spear of light."

I clicked my tongue in annoyance like a rebel would do. "It's not like I'm going to that place whatsoever. Someone pulled me in..."

Issei is looking at me like I'm a reckless idiot right now, but shocked when I act like a cocky rebel.

"Never get involved with people from the church." Buchou continued. "Especially the Exorcists. They could easily kill every single one of us since they have God on their side. It's even more dangerous if they have a Sacred Gear, you'd be standing on the boundary of death. You could avoid death as a human because of the reincarnation but if an Exorcist kills you then you'll become nothing. You'll feel nothing. Do you have any idea how serious that is?"

"Try trapped in Nightmare Universe and be forced to reset every 100 years?" I pointed out before realizing what I just said. They all looked at me confusedly, with me trying to wave it off. "Forget that...I get the point already. Are you satisfied?"

"I'm not!" Bill comes in and glares at me as he turns red in anger. "Why did you remind me of that horrible memory?"

"Oh, man up will you. It's have been trillion of years ago!" I glared at him, looking elsewhere.

"If you in my shoes one day, you too will be in pain." We both scoffed at each other, crossing our arms. I then heard Buchou cleared her throat, gaining back my attention.

"Sorry Buchou." I sighed at sitting at my spot. "Need to blow off some steam on a flying triangle demon in my mind."

Buchou sighed and shook her head. "I'm sorry if I got too heated. Just be careful from now on."

"No promise though." I stoically replied which she gave me a cold glare.

"Ara ara, did you finish lecturing the poor cute thing?" Issei and I both jumped. I had no idea Akeno was even in the room. I then proceeded to blush furiously when I realized what she said.

"Hehehe, what's the matter?" Bill teased as he floats in front of me. "You crush called you cute? I can't believe you already forgot about blonde."

I clicked my tongue pulling out a book to hide my ever growing blush.

"Akeno, did something happen?" Buchou asked her. Akeno's expression went from smiley to serious.

"The Arch Duke has sent us an order for a hunt."

"Is it Duck Season already?" I casually said while scanning my book quickly.

[Timeskip]

All of us were at a disused building on the outskirts of the town. I then looked at pretty boy who was beside me.

"Quick question before we enters, what is Stray Devil?" I questioned them while dusting off my fedora. "Other than homeless devils that is."

"Stray Devil starts out as a devil servant's." Kiba answered me.

"Like us." Issei joined the conversation, glancing at Prince Charming.

"No, not exactly. Once in a while a servant rebels and kills their master to gain freedom then they become strays."

"Must've good reason I suppose." I put on my fedora as Koneko glanced at me when I said that.

"Reports say that the stray has been tricking people into abandoned house and eating them." Akeno told us with a small smile on her face.

I raised my eyebrow, looking at the black haired girl before looking back at the building. "They got lured into this place?" I scoffed, showing some grin on my face. "Whoever was stupid enough to be tricked into there was probably doing the world a favor. It just natural selection."

We all got into the house with me looking around for some clues. "Tch, couldn't believe this fools fall into seduction..." I clicked my tongue in annoyance, earning everyone attention.

"Wait, why do you say that?" Bill questioned me, currently confused by what I mean.

"Clothes were unscathed by any blood or tear in it." I deducted as I crouched on one of dusty shirts on the floor. "Victims were mostly males as there's no evidence of woman undergarments. Probably from the act of lust...they opened up their shirt and was about to some indecent stuff until-"

"They got eaten by her?" Issei perked up from my deduction. "So you mean-"

"Our stray devil is a female." I patted my hand before standing up.

"Good deduction skills." Akeno compliment as she put her hand on her mouth.

"I read Sherlock Holmes."

"I smell blood." Koneko said. She covered her nose with her uniform sleeve.

"Issei, (Y/N), this will be good opportunity for you to experience what it's like in a fight." Buchou told us.

"Are you serious!?" Issei exclaimed. "We won't be of much use!"

"Yes, it's still impossible now." She said bluntly. Issei looked a little hurt as I felt Bill was a bit of annoyed when she said that. "Today, you'll be observing while we fight. I'll explain the traits that all of my servants have."

"Traits your servants have?" Issei looked confused as hell.

"Devils give specific traits to those who will become their servants." Rias informed us. "Because of the war between the Devils, Fallen Angels and Angels, all sides lost most of their troops. In the end no one won."

"If I am in that battle, I will win." Bill simply said while crossing his arms.

'Sure...lose to children..' I giggled a bit, getting the nerve of the triangle demon.

"The Devils were no exception." Kiba picked up. "Devils with Peerages commanded 20 or 30 troops at a time but lost most of their underlings during the war. So many were lost that it was impossible to form a new army."

"Most Pure-Blood Devils passed away during the war." Akeno continued. "Even after all this, the three factions couldn't live in peace with each other. Even though they are in a similar situation to the Devils. Therefore, we can't let our guard down even now."

"After a while the Devils thought of a new way to create small groups of soldiers." Buchou spoke again. "That is the Evil Piece system."

"Evil Piece?" I asked what both Issei and I were probably thinking.

"What the heck those that mean?" Bill got curious about this.

"It was decided that the traits of human game 'Chess' would be given to servant Devils." She explained. "Chess has actually become quite a popular game among Devils since then. The master of the peerage is the King. In our case, that is me. From there they created five other traits: Queen, Knight, Rook, Bishop and Pawn. Since they couldn't create an army, they provided a small number of Devils with large amounts of power. This system has only been going for a few hundred years and is already popular."

"Sounds stupid..."

"They started to compete against each other. 'My Knight is stronger!' or 'My Rook is strongest!' and as a result, High-Class Devils began to compete in a Chess-like game against each other using their servants. We call this a Rating Game. It became very popular amongst the Devils and there are even tournaments for it. The strength of their Pieces and their skill at the game affects their social position and their Peerage. There is a thing called Piece Collecting where they gather humans with high-level talents and make them into Devil servants. The talent of their servants directly affects their status."

"I suppose it just meant that our pride as Devils rested with the Rating Games, am I right?" I implied as she nodded in agreement. "Oh, that's fun!"

"I saw some sarcasm there, bro..." Issei deadpanned.

"I'm not a matured Devil yet so I can't participate in the official tournament. So we won't need to take part in one for a while." She informed us.

"I knew this devils were posers." Bill laughed at them without no one noticing except me...cause I'm the only one that can see him. "I can't believe that their basically use their servants as glorified Pokémon."

'Way to make us feel important...' I told him.

"So, what Pieces are we?" Issei asked her.

"I'll admit, I was also curious." I joined my brother, curious about this matter.

"You are both..." She stopped there as we can feel the killing intent in the air. I could feel that something was approaching.

"I can smell something disgusting." A distorted voice says. It sounded like it was under the ground. "But it also smells delicious. Is it sweet? Or is it sour?"

"Probably your morning breathe." I called the devil out while putting both of my hand in my pocket. "You should really brush your teeth then."

"Stray Devil Vaizor!" Buchou called out. "We are here to eliminate you!"

"Boobs!" Issei show a shit gritting smile, earning a face palm from me.

"Oh, brother..."

A massive amount of abnormal laughter echoed around us. It was both amused and cruel sounding.

Something emerges from the shadows. It's a...topless woman? Hold on, why is she floating? No, not flouting. A heavy footstep is heard. Followed by another and another. Soon enough we saw that she wasn't floating, she was the top half of some sort of gigantic beast! It was holding some form of spear in each hand. The bottom half looked like a fat-ass lizard. Four abnormally large legs and a snake tail. Massive sharp claws were located on each of its feet. This thing was about five metres tall!

"You one ugly motherfucker." I muttered in disgust.

"Leaving your master's side and rampaging as you please warrants death." Buchou said in a serious tone. "In the name of Duke Gremory I will gladly eliminate you!"

"You are very cunning for a little girl!" Vaizor hissed as she played with her boobs. "I will rip apart your body until its color is red like your hair!"

"Keep it PG-13 here, thot." I pinched my nose in annoyance.

"Continue please." Issei told her.

'Oi, Bill.' I telepathically called him. 'I just unlocked one of your power. How the hell I used it in battle? Magically creates a sword out of thin air?'

"Yeah." Bill simply answered as I deadpan by him. "What? You want me to shake hand with you kid? You need to learn to sort this thing out of your own."

'You just want to see me being tortured.'

"Absolutely."

'Fuck.'

"On the bright side, I really want an apprentice, so you'll do."

Buchou simply laughs through her nose. "Grunts always do speak in such a stylish manner. Yuuto!"

The next thing I knew Kiba, who had been stood next to me and Issei, had disappeared in a blur.

"Yuuto's position is that of the Knight." Buchou explained. "Its trait is speed so those who become one gain a vast amount of it."

Vaizor was swinging its spears around trying to hit Kiba but to no avail. It might as well have been trying to hit the wind.

"And Yuuto's best weapon is his swords."

Kiba stops for a moment, holding a sword I'd never seen before, and slashes. He disappears again with the screams of Vaizor after taking off both of its arms. The blood was squirting everywhere.

"When combining unseeable speed and the sword skills of a professional Yuuto becomes the fastest Knight." I saw someone approaching Vaizor's legs... wait a minute. That's Koneko!

"Next is Koneko." Buchou continued like nothing was happening. "She is my Rook. The Rook's trait is..."

"Damn insect!" Vaizor screamed while lifting its leg before stomping the white haired girl.

"Koneko!" I yelled in panic only to notice that Vaizor's foot hadn't hit the ground. The smallest girl I'd ever met was holding up Vaizor's leg!

"The trait of the Rook is simple. Incredible strength. And a great defense. It's impossible for a Devil of that caliber to overpower Koneko. It can't crush her."

With a grunt Vaizor was lifted into the air by the loli beneath it.

"Fly." Was all Koneko said before jumping and punching the monster into the giant stone wall on the other side of the room.

"Huh, neat." I said as she got back to us. She looked at me for a moment and nodded before turning to observe with us.

"Lastly, Akeno."

"Ara ara, what should I do?" Akeno asked herself as she approached the monster with a smile on her face.

"Akeno is a Queen. She is the second-strongest in the group, after myself. The Queen Piece gives her all the traits of a Pawn, Knight, Bishop and Rook."

Vaizor growls while staring at Akeno. Akeno makes an amused laugh at seeing the monster's gaze on her.

"Ara ara, seems like you've still got some energy left." She said. "Then how about this?"

Akeno points her hands towards the sky. The sky flashes briefly and a bolt of lightning comes down and strikes Vaizor who then began screeching in pain. Its body was burned, crispy and smoking from the impact.

"Ara ara, looks like you can take some more!"

Another lightning bolt hit the monster than now sounded like it was already dying from the pain. And even then, Akeno strikes it a third time. She was laughing the entire time she was doing this.

"Akeno excels at attacks using Demonic Powers. She can use elements such as lightning, ice and fire. She's also the ultimate sadist. Usually, she's very kind, but when the battle starts she won't stop until she's calmed down."

"The ultimate what now?" I blushed at the word, tried to cover my blush with my fedora.

"I felt a bit uncomfortable with that..." Bill commented as the flying triangle demon shivered.

"I'm caught in the rift between aroused and terrified right now." I realized what I just said before blushing madly. 'FUCK! Did I say that out loud?'

"You did kid. You sound like your brother..."

'Shut it!'

Like Bill said, apparently I did because Koneko is glaring at me something fierce. Does that mean she's interested? Most of the time she just doesn't seem to care about what I'm saying.

Buchou laughed. "You don't have to be afraid, (Y/N). Akeno is very kind to her friends so it's not a problem. She even said that you were cute. Next time, let her spoil you and she'll definitely hug you kindly."

"Ufufufufufufufu. How much more lightning can you take, monster? You can't die yet. My master needs to finish you off." Akeno laughed at the end.

These lightning attacks continued for another few minutes before Buchou ordered her to stop and stepped towards Vaizor. She pointed her hand at it.

"Any last words?" She asked.

"Kill me." Vaizor replied quickly.

"Then disappear." A mass of black, demonic energy erupted from Buchou's palm at the monster. In front of my eyes, I saw that Vaizor got completely obliterated, leaving no evidence of its presence here.

"Good work everyone." Buchou said.

"Buchou," Issei spoke up. "What pieces are (Y/N) and I?"

"You're both..."

"Get down!" I shouted as pulled Buchou away from another stray devil. My left eye erupted into blue flames as snapped my held my hand out. The devil than shrieked in pain as I saw its leg turns into stone.

"W-what is this?!" He shrieked as I helped my leader out. "H-how did you know I was here?!"

"Kind of obvious really..." I told him, dusting my fedora while a sword appeared in my hand with a snap of my finger. "Judging by the amount of the kills, it's double the need for that thot earlier. She attracts and you the one who the killing."

"What...WHAT IS THAT?!" He shouted in horror as I looked behind me and saw Bill waved at him.

"Wow, you can see him? Glad I'm not the crazy one..."

"Hello!" Bill greeted before turning into sign that said, 'Omae wa mou shindeiru'.

"P-Pleased...spare me!"

"After almost kill tomato hair..." I stabbed the sword on the ground and walked away towards my friends. "I will."

Everyone was shocked as I made my way to them. The stray slyly smile as he was about to lunged at me...but he noticed that he could not move his body. He looked down and saw that his body slowly turning into stone, horrifying him even more.

"Y-You lied to me?!" The stray shrieked as I stopped midway.

I lazily turned around before giving a sadistic smile. "You ask me to spare you. I did spare you from killing but you didn't ask me to spare you from turning into stone...bye bye!"

"Classic deception~!" Bill gives me a thumbs up. "You're one mean devil right there."

"Stop, please I do anything! Please let me-" Before I knew it, he already turned into stones while I made my way towards Buchou and the others.

"What was that?!" Issei exclaimed as I shrugged.

"Like Medusa, I stone motherfucker who looked at me wrong." I tilted my head with the smile still on my face. The flames from my left eye died down as I looked back at the statue. "I can turn him into a toaster though."

"No thanks."

"I knew it." Buchou called out as she smiles at me. "You are more than meet the eye."

"I'm a transforming robots?" I joked.

"You're different than any devils I met. Interesting fellow I must say. You have lot a magic in your body that not even one of my evil pieces accepted you...until I choose that particular piece."

This peak my interest as she smiles. "Everyone, I present to you...The Co-President of Occult Research Club...(Y/N) Hyoudou...as he possess the King Pieces."

Everyone was taken aback from the news including me while my triangle flying devils clapped at me.

"Bravo! Bravo!" Bill wiped a fake tears in his eyes. "You made me proud, you son of a gun."

"Neat." I simply replied with a smile as my brother patted my back.

"Damn, I could not believe you had it within you!" Issei laughed happily before looking at Rias. "So, what is my piece then?"

"You are my Pawn." She said with a smile, and with that Issei smiles dropped as I sympatically patted his back.

"Well, it's official." I put my hand around his shoulder. "You sucked...really hard..."

"...Fuck you bro..."

"Love you too!" I ruffled his head as Issei dropped one tear of despair.

"HAHAHAHAHAHA!" Bill was laughing his ass off at my brother. "He's truly are sucks! A lot!"
