Hello, everyone! This is ArtLotus. And I'm here with a new Fanfic that I've been thinking of doing for a while, and with a supportive friend of mine suggesting that I should do it, I've managed to finally do it officially. But don't expect me to update fast okay? I got enough Fanfics to cover for now.

Okay, after reading some of your reviews, I admit that Izayoi should be pure human. But what I don't agree is he should be in a romance genre. After all, he has a caring side of him.

Anyway, I've rewritten the story a little bit. And I hope you respond positively to this.

Well, let's see how Izayoi handle the World of the Devils, shall we? I'm gonna go, Ja'ne! ArtLotus out!

(Highschool DxD – Mondaiji tachi ga Isekai Kara kur sou desu yo?)

A Problem Devil

Sakamaki Izayoi is a 17 year old teenage boy. In the human world, he pretty much seems to be a normal teenage human boy. But what they didn't know is that he has a mysterious yet powerful gift. A gift that could deflect and even destroy a Ultimate-Class Devil power, rendering the said power useless. Not much are known about Devils as stated by the humans as they didn't believe in them, and just waved it off as superstitious rumors.

Back to the story at hand, Izayoi is a transfer student who is to be transferred to the co-ed school Kuoh Academy. He had been registered to the said academy by his old and slightly annoying friend, Sirzech Lucifer formerly known as Sirzech Gremory, to which the Gremory's is his family's name. The title Lucifer was bestowed upon him after the old Satans' faction had been destroyed by the new Satans led by Sirzech himself.

Other than that, the two of them had known each other and they became best friends after an event that took place in the Underworld to which Izayoi had challenged Sirzech to a battle between themselves.

Before the battle, he walked aimlessly around in the strange world he was teleported to. He didn't know who had brought him in the strange world in the first place, but it was strangely someone who had the power to summon him to the Underworld.

At first, he thought if he should went inside the red intricate portal in the first place, or not. But when he sensed the immense power the portal held, he immediately theorize that someone or something would be extremely strong and powerful from performing the portal's creation, much to his amusement. But before he step in the portal, he thought about the fact that he would never return to his world if he step inside the portal, which would take him to oblivion or someplace. But then, he instantly thought about how bored he was by fighting with weak bullies and delinquents in his world, to which he decided to step in the portal without hesitation, After he stepped in, he was instantly teleported from the clear bright sky of his world, to a dark red sky filled with dark clouds.

He decided to just wander around the forest that he teleported to, and wait until he could find something fun to do. After a while of wandering, he sensed that someone was following him behind the trees. He then continued walking along the forest, leading the follower to a deserted wasteland where he arrived.

And so, after the battle between Sirzech and himself, he didn't expect Sirzech to have that shock, awe and surprise look on his face, when he had been beaten by him.

Flashback…

"You know I can sense you. Stop hiding, and just come out." A 15 year old Izayoi said standing in the middle of a deserted wasteland, of the Underworld. He had his hands pocketed inside his pocket pants.

"Ah… I thought I would never be found out. But who am I kidding?" Sirzech asked amused as he step out from the trees he was hiding. He look at Izayoi with a smile, sensing that he had great power in him, to which it draws him to where they were now.

"You know, how about you become a member of my peerage? I've been observing you for a little while from the Underworld, and might I say, you're a mysterious boy." Sirzech said thoughtful with a hand under his chin, while Izayoi held a smirk.

"A member of your peerage?" Izayoi asked as he thinks for a while, and then he turns to Sirzech to give him an answer. "How about no?" He answered as Sirzech raised an eyebrow at his unreasonable answer.

"Do you know what is a peerage?" Sirzech asked with raised brows.

"No, but the way you've said it, I assumed it's a kind of group or something. And you wanted me to become a part of your peerage, right?" Izayoi simply stated as Sirzech look at him with a smile.

"You're right. But if I may, let me explain it to you in full detail. A peerage is a group consisting of a King, Queen, Bishop, Knight, Rook and last but not least…" Sirzech explained as Izayoi answered it for him.

"Pawn." Izayoi answered as Sirzech nodded, but realizes that he forgot to introduced himself to Izayoi.

"Oh, I forgot to introduce myself first. I'm sorry." Sirzech said with a apologetic bow.

"My name is Sirzech Lucifer. I'm from the Gremory Family. I'm a devil and I'm the ruler of the Underworld, this world you're in now." Sirzech stated as Izayoi look at him.

"Lucifer, huh? That name is just a title, right?" Izayoi asked as Sirzesh smiled and nodded.

"Yes, it's a title. My former name is Sirzech Gremory, but I'm addressed as my current name now, which is Lucifer instead of Gremory." Sirzech explained as Izayoi nodded in understanding before he ask a question to which made him curious.

"Devil?" Izayoi asked as Sirzech realizes again that he didn't know what Devils are.

"Nevermind that. I'll explain it to you later." Sirzech said with a sheepish look, while waving his hand in dismissal.

"...Okay. So, seeing as you observed me, I assumed you're the one who teleported me here, correct?" Izayoi asked knowing he would found out about his previous question sooner or later but he wanted to know who had teleported him after all the trouble he went through wandering in the Underworld without something exciting for once.

"Yes, I'm the one who teleported you into this world of mine. I'm sorry if it had taken you by surprise but I've wanted to ask you directly to become one of my peerage. For a while, I've noticed you're different from other humans in your world and I tend to find out." Sirzech explained with a smile as Izayoi kept looking at him. But then a smirk made its way on his face, having found something exciting and fun to do now.

"Well, how about a bet then? You said you wanted me to be a member of your peerage, and I nicely declined. To start the bet, how about a battle?" Izayoi exclaimed as Sirzech raised his eyebrow at his strange request, to which Izayoi noticed.

"Battle?" Sirzech asked as Izayoi smiled amusingly.

"You know, I've been living a boring life till now, nothing but weaklings to whimper under my feet. It sickens me, you know?" Izayoi explained. "Since you're the ruler of the Underworld, Maou-sama. I want to fight you." Izayoi smirked as Sirzech thought for a second if whether he should accept his invitation or not. He was contemplating on fighting Izayoi in a battle. Because he is the strongest devil in the Underworld, and to fight Izayoi would be a unfair advantage to him, but nonetheless he chose to accept his request.

"What are the terms of the battle?" Sirzech asked.

"No rules. Just fight." Izayoi stated with a grin, clenching his fists. "Oh, I forgot. If I win, I'll walk away and explore this world for a while. After I'm done with that, you'll send me back to my world. It's as simple as that, wouldn't you say?" Izayoi asked with an amused smile as Sirzech listened in on his offer.

"You know that's not a fair offer. What if you lose?" Sirzech voices his curiosity.

"Who said anything about me losing?" Izayoi stated with grin.

"Okay then, if you lose you'll be a part of my peerage, how about that?" Sirzech asked with a smile as Izayoi shrug his shoulders.

"Whatever you want. But are you willing to?" Izayoi asked as he put his right hand on hip while Sirzech held a smile on his face.

"I'll accept your challenge. But trust me, I'm not going to go easy on you." Sirzech said with a serious face.

"I never said anything about going easy." Izayoi said with a smile, as he crouched a little. "I always want to see what the Lucifer is capable of, and this is going to be a fun fight…" Izayoi whispered as the two stood face to face in the middle of the wasteland.

"Begin." Izayoi said as he suddenly disappeared from sight, surprising Sirzech.

"Where did he go?" He asked looking around for Izayoi.

"You should look behind you." Izayoi said appearing behind Sirzech, to which he noticed too late as he was instantly sent to the other side of the wide area. Colliding with trees the most, while a large crater was being shaped on where Sirzech lay after being punched by Izayoi.

Sirzech stood up as he brushed his clothes off the dirt that covered it, and then look at Izayoi in the distance with his arms crossed.

"I can't sense him. His speed is too fast for me to even detect it, without him getting to me first. And his strength, I never saw anyone wielded that much strength before. By his strength alone, he could greatly outrank the rook's capability of strength if he punched that hard. I doubt that Sutr would be able to defeat him, much less touch him." Sirzech explained to himself holding his injured side.

"What's the matter, Sirzech? Tired already? Where's the Lucifer who is ruling the Underworld?" Izayoi provoked as Sirzech narrows his eyes, taking the battle more seriously.

"You ask for it." Sirzech said as he held up his hand that was surrounded by red radiant energy. He then directs his hand towards Izayoi who stood waiting for Sirzech to attack.

Suddenly, small spheres of red burst out of Sirzech's hand and instantly charged towards Izayoi, who held a grin.

"Now you're getting serious, Sirzech." Izayoi said to himself, as he tighten his fist, while the spheres were coming closer and closer to him.

"Now this is getting fun!" Izayoi exclaimed as he dash straight towards the array of spheres that were headed towards him. One of the spheres that were the closest to hit Izayoi, was suddenly destroyed in a shiny explosion, covering Izayoi with the debris.

"What? Did he just destroyed it?" Sirzech thought in disbelieve.

After the debris clears up, Sirzech could see that Izayoi was the one with his fist extended from his destroyed sphere was, that he destroyed his sphere with just a single punch of his fist.

"You know this is getting easy, Sirzech!" Izayoi called out as he stopped in his track while the red spheres were still heading towards him. Izayoi grinned as he punched one of the spheres that was the closest to him, instantly destroying it. Izayoi then back palmed one of the spheres, maneuvering it from a different path as it hit a tree, and explode.

As the spheres were slowly being punched on one by one, Sirzech couldn't believe that he was seeing it in front of his eyes. Each of the spheres were equivalent to his power as a High Rank Devil, even if they were small. And Izayoi just punched them all with ease, like it was nothing, and he didn't get a single burn to his arm or hand when the spheres exploded right after he punched them.

After all the red spheres were gone, Izayoi look at Sirzech who stood there with a shock, awe and surprised look on his face.

"You should not let your guard down." Izayoi informed as he instantly vanished from his spot, while Sirzech who was eyed wide at the show before him, shook his head out of his thought as he focused on to the fight that will determine if Izayoi could be a member of his peerage or not.

"I've totally underestimated him. His strength and speed are on another level!" Sirzech said in his mind as his eyes widen immediately, sensing something or someone was behind him.

Turning around, he was greeted by Izayoi with a smile on his face, "I win." Izayoi declared as he punched Sirzech in the stomach, prompting him to cough up blood as Sirzech was sent flying up into the sky.

"Ugh..." Sirzech winced as he look at the ground that was getting farther and farther away from him. Just as he was about to fall back down with his back facing the ground, his eyes immediately spotted Izayoi above him, surprising him.

"Lights out, Maou-sama." Izayoi exclaimed with a smirk.

With his air that was knocked out from his lungs, Sirzech attempted to end the battle with the both of them going down together on the ground. He gathers his energy and convert his body into a condensed amount of Power of Destruction in the form of a human-shaped aura.

"Another one, eh? Sirzech?" Izayoi asked with a smirk, falling head first while Sirzech who was falling head first too, waited for Izayoi to attack unless he would be burned.

"I'm going to take you down with me." Sirzech said coughing as the Power of Destruction immediately spreads all around him including heading towards Izayoi to attack.

"In your dreams, Sirzech." Izayoi said as he punches the Power of Destruction, that was heading towards him. Izayoi held a hidden smirk, feeling the force of the destruction in the aura that was slowly pushing him, but the way that he was falling head first, revert the situation.

"I didn't know you had something like this, Sirzech. I'll give you that." Izayoi commented as Sirzech chuckles.

"But I'm going to win." Izayoi stated as Sirzech look on in shock, awe and surprise as Izayoi slowly punched his aura to him. And just as the aura connected to Sirzech, Izayoi pulled back his hand, as he spins around and punch Sirzech with his left hand, and suddenly the aura that surrounded Sirzech was completely gone, vanished.

And with the punch connected, Sirzech's aura gone, he instantly plummeted towards the ground, crashing head first causing the whole area to shake by the force of Izayoi's punch.

Izayoi landed gently onto the ground with his two feet, as he walked towards where Sirzech was. He looked down at the giant crater that was a big hole in the ground. He look down and immediately saw Sirzech laying there unconscious.

"Better get you treated. Or I'll have the whole Gremory family to fight." Izayoi said with a sigh, as he jumped down in the crater and helped Sirzech up, putting his hand on top of Sirzech's shoulder while his other hand grabbed Sirzech's left hand and pulled it over his neck, trying to support him to make it easy for him to carry him up to the high ground.

After a while, Izayoi slowly grabbed Sirzech by his back and pulled him out of the crater, as Izayoi lay on his back against the ground, feeling the wind blowing against his hair.

"Are…" Sirzech said as Izayoi just looked up at the sky while he listened to what Sirzech has to say. "You a devil?" Sirzech asked as Izayoi laughed.

"Last time I checked, no." Izayoi answered as Sirzech tried to get up but with the painful sore he felt all over his body prevented him from doing that. "You should rest from your sore." Izayoi advised as he took a whiff of the air.

"Yeah… I think I should do that." Sirzech said as he turn on his back, looking up at the sky.

"Will you tell your family about this? About how you got badly hurt?" Izayoi asked as Sirzech chuckles.

"How could I not? There isn't any devil who could beat me in the Underworld. But shockingly a human just did. And he just did it with his bare fists" Sirzech said with a dry chuckle, as Izayoi smiled.

"Yeah. Who wouldn't?" He asked as Sirzech nodded.

"I hope I get to see Rias-tan in time. She must be so worried about me." Sirzech said in his sis-con attitude, as Izayoi raised an eyebrow.

"Is she your sister?" Izayoi asked as Sirzech nodded.

"Yeah. Her name is Rias Gremory." Sirzech said pronouncing her name to Izayoi.

"Rias… Is she really that worried about you?" Izayoi said raising an eyebrow as Sirzech chuckle.

"I don't know. But if she heard her onii-san got beaten badly by someone, she will get that person and ask him to become a part of her peerage." Sirzech said looking up at the sighing Izayoi. "I mean that person beat the Lucifer, the ruler of the Underworld. Who wouldn't want someone like that in their peerage?" Sirzech said to Izayoi.

"Yeah, but that will be a problem." Izayoi stated as he then shrug. "But I'll never know. Maybe it will be fun joining your sister peerage." Izayoi said with a smile, while Sirzech sweatdrop and awkwardly laugh.

"But you don't want to join my peerage, because?" Sirzech asked.

"You're a guy. I don't take orders from a guy." Izayoi said as Sirzech awkwardly laugh again.

"I see. Well, maybe Rias-tan would love to make you a member of her peerage. And by the way, she is 15 years old. And I think it's time to find her someone whose the same age as her, strong, fast, smart and being able to beat the ruler of the underworld." Sirzech teased trying to set his sister with Izayoi.

Izayoi grabbed a pebble beside him, and throws it at Sirzech's head making him wince from the pain.

"Ouch! Hey!" Sirzech exclaimed looking up at the smiling Izayoi.

"I didn't do anything." Izayoi said sarcastically.

"I don't know. Maybe I'll join your sister peerage." Izayoi said as the answer puts a smile on Sirzech's face.

"Really?" Sirzech asked.

"But I'm still new to this thing." Izayoi stated as Sirzech waved his hand in dismissal at Izayoi.

"Don't worry. I'll teach you about it. Including about the devils, fallen angels and angels." Sirzech exclaimed as Izayoi raised an eyebrow.

"Fallen angels? Angels?" He asked.

"Not to worry. I'll teach you about that later." Sirzech stated as Izayoi nodded with a smile.

"We'll see. Maybe I'll take a visit to your place when I'm exploring, to meet my soon to-be ojou-sama." Izayoi said with an amused smile, while Sirzech nodded in agreement and smiles. He could have Izayoi as his brother-in-law just fine, even if he is a human. But knowing that he was stronger than him, he could easily protect Rias from harm. And if this wasn't an official battle commenced by the Four Satan Families, he could lose his position as Lucifer to Izayoi permanently.

"Well, if that's it. I'm going to take a walk around the Underworld." Izayoi said getting up from his position, while Sirzech look up at him.

"You're leaving?" Sirzech asked confused as Izayoi nodded.

"Yeah, I'm going to find some strong devils to fight around here. I know you're the strongest devil in the Underworld, but I'll just test my luck on finding someone to fight." Izayoi said as Sirzech shook his head as he slowly stood up, having been rested enough to stand up.

"But will you see Rias?" Sirzech asked.

"I don't know. We'll just have to see." Izayoi stated as he offered a smile to Sirzech, to which he replied with a smile of his own. "I'll see you around, Sirzech. But don't forget to send me back, alright?" Izayoi exclaimed turning around and walking away but not before waving his hand behind him at Sirzech, while he leaves.

"Okay. Meet me right here, when you're finished with your exploring." Sirzech said with a smile as he watch Izayoi leaves.

"Right." Izayoi shouted as he continues to leave.

After Izayoi left, Sirzech winced as he clutched his sore side from the injury that Izayoi gave in their battle.

"He sure can punch hard… And he's a human." Sirzech winced from the pain, as he then walked towards his castle while silently hoped that he wouldn't get pulverize by his wife, once he gets home.

Present…

"This must be the Academy." Izayoi said looking up towards the Kuoh Academy.

"I can tell this is getting fun already…" Izayoi whisper to himself, as a smirk started to appear on his face.
