Chapter 3: The Occult Research Club?

"Ugh..." Izayoi groaned as he slowly open his eyes to see his room's ceiling. He yawns as he was about to get up, but he stopped as he feel a weight on top of his chest. He then look down to see Rias laying down on his chest with her snuggling closer to him. He then realized that she was completely naked without a thing to cover her up with and she was pushing her body closer to him, pushing her large breasts against his chest.

He recalled the events yesterday, after Rias said that she wants to get to know him more, he escorted her to his home, to which she accepted with a smile. The two then arrived at the said home, and Rias look at it with an awe look. It was home, and not just an apartment, it was a real home, with a gate in front of the two storey house.

Izayoi then gestured her inside, as she kindly walk inside and she was visited with a clean, nice living room. She walked inside further seeing the kitchen, and the dining room in front of it.

Flashback...

"I'm going to sleep... You can handle it from here, right?" Izayoi asked as Rias nodded, while Izayoi walk upstairs to his room. After she heard the door close upstairs, she begin her exploration of the house.

She was surprise as she thought that Izayoi was a Juvenile Highschool Student, that everyone in his old school called him, and she thought that he couldn't have kept his house clean or even own a house. Delinquents mostly live in apartments, and she could now believe that Izayoi wasn't that type of delinquent at all. Besides, if he is a delinquent he would be doing bad things instead of defending the white haired girl she knows earlier at school.

Rias then yawns, tired from her exploration of Izayoi's house and school earlier. She thought to teleport to her club, but she thinks otherwise as she headed straight up to Izayoi's room.

Once she arrived at his room, she slowly open his door and poke her head inside, to see Izayoi asleep on his bed. She giggled as she quietly step inside the room, and carefully strip of her school uniform and her underwear. She then slowly climbed on the bed and gently lay her head on Izayoi's chest, with her hands laid beside her. She smiled a small smile, as she closed her eyes, feeling the warmth that Izayoi gave, and she loves it. So, she snuggled in closer to Izayoi while she sleep blissfully.

Present...

"Isn't this nice? I wish I could wake up to this everyday." Izayoi comment with a smirk, looking at the naked Rias.

"Well, why can't we?" Rias asked waking up from her sleep, looking at Izayoi with one of her eye poking out at him from on top of his chest, while Izayoi look at her with a smirk. "I didn't know you slept naked. If i had known, yesterday would be a lovely night, with scented candles everywhere." Izayoi commented as Rias blushed a little from Izayoi's statement.

Izayoi then leaned closer to Rias, who just look at him in curiosity and with blushing cheeks.

"And I didn't know you had such a nice body, Rias ojou-sama." Izayoi whispered huskily in her ear, as Rias blushed crimson. "I could just eat you up..." Izayoi whispered again to her, while Rias just blushed, listening to his words. "But unfortunately, we have to go to school." Izayoi said to her with a smirk, as Rias shook her head out of her thoughts as she look at him and then nods her head, agreeing with him.

They both stood up from the bed, as Izayoi stretched himself while, Rias put on her panties. "Izayoi-kun, can you clip my bra?" Rias said pulling her hair aside revealing her unclip bra. Izayoi walked over to her and clipped her bra.

"Thank you." Rias said with a smile.

"No problem." Izayoi said as he picked up a towel from his closet and walk inside the bathroom. Rias then picked her neat folded school uniform on top of Izayoi's desk beside his bed, as she dress herself up for school. While Izayoi was still in the shower, Rias looked around the room as she saw that he had a collection of books on top of his work desk. She then spotted a picture frame on top of his desk as she walked near it, to get a closer look.

She picked up the picture frame and examined it, seeing that the frame held a picture of Izayoi and a blonde haired women standing side to side. They were smiling as the blonde haired women held both of her hands on the young Izayoi's shoulder, while she crouched down to his height, with her head beside his. Rias smiled at the picture, as she look at it for a while.

"Looking around the room, huh?" Izayoi commented as Rias turns around to look at him, who wore a short sleeved black shirt. Izayoi then noticed the picture frame in her hands. "So you've seen the picture..." Izayoi said as Rias realized the frame in her hands as she puts it back on the desk.

"Do you mind?" Rias asked as Izayoi waved his hand in dismissal. "No, I don't mind. She would have loved to get to know you, if she'd known that there was a naked girl sleeping with her son." Izayoi joked as Rias smiled at him, but then a frown was smarred on her face.

"What happen to her?" Rias asked as Izayoi look at her. "She died. She was extremely ill. And the doctors said that they couldn't do anything about it." Izayoi said recalling the sad memories, while Rias looked at him with a sad frown, sympathizing with him.

"Well, it's no use on bringing up the past. We have a school to go to." Izayoi said with a smirk, as he open his door and left, leaving Rias. "Hey, wait up." Rias stated as she too left the room, and the two left the house to school.

Kuoh Academy

"Learning is boring..." Izayoi mumbled as he amd Rias walk past the school gate, arriving to school in time, while students from the school were shocked and surprised to see Rias and the new transfer student walking side by side to school.

"Hey, isn't that the transfer student? And isn't that Rias-senpai!" A girl said to her friends as they went eyed wide upon Izayoi and Rias arrival.

"OH MY GOD!" cried a random girl as a crowd gathered in front of the school.

"Izayoi-kun is walking together with Rias onee-sama!" She said as Izayoi raised an eyebrow at the gathering crowd, while Rias who wore a small smile on her face, just waved at the crowd.

"They look so cute together!"

"The transfer student really outdid himself."

"Doesn't Rias-senpai look a lot happier than usual, maybe they are in love!"

"We really are something to caught this much attention." Izayoi commented glancing at the students that were looking at them with surprise and awestruck looks.

"But who wouldn't? A transfer student walking side by side with a beautiful girl like you. Who wouldn't want to start the gossips from spreading all around the school?" Izayoi said as Rias giggled and slightly blushed from him calling her beautiful. As they neared the class, Izayoi slide the door for Rias and gestured his hand inside, as Rias smiled and entered the class, followed by Izayoi.

"Thank you." Rias said as Izayoi smirk, as Rias sat on her chair beside the window, while Izayoi sat on his chair next to her.

Izayoi lay his head on his hands, as he look to see the third year students come inside the class, apparently knowing that class session start soon.

Izayoi yawns as he saw a teacher coming inside the class, as he stood in front of his desk before the class.

"Class, today we'll be learning about history. Pull out your book, and turn to page 57." The teacher said as Izayoi wore a smirk, knowing history pretty well from his experience from travelling over the world.

After School

"Izayoi-kun, have you joined a club yet?" Rias asked as class session had ended earlier.

"No, why?" Izayoi answered as Rias smiled at him.

"Then, follow me to my club." Rias said as she left the class, followed by a curious Izayoi.

Time Skip

"So this is your club?" Izayoi asked looking up at the big club before him. He noticed that it was different than the main one, older and had a slightly different style to its architecture. Despite it's obvious age, it was still very well maintained.

"Yeah. Come inside." Rias stated as Izayoi followed her inside the club.

When Izayoi come inside, he immediately saw the inside of the room was clearly a clear out classroom. The floors were made of wood panels and there was a chalkboard hanging on the wall behind a desk. All of the students desks had been cleared out and in the center of the room was a chalk drawing of a large and complicated circle that Izayoi would know, as he listened to Sirzech all day about circles.

There was were several furniture like chairs, desks and couches. Izayoi then spotted the white haired girl he saved yesterday, sitting on the couch, to which Rias noticed as she pointed her hand to the girl. And today, he could get a clear view of her, she looked very young to be in school, but with her slim, petite figure and cute lolita face, she looked to be a year or two younger.

She had hazel colored eyes and her hair was a pure white color with two long bangs at the front that ran down past her shoulders and several loose bangs hanging over her forehead, while the back was cut in a short bob cut hair style. On either side of her hair were a pair of black, cat shaped hair clips.

"I see you remember her from yesterday. Her name is Toujou Koneko. She's a first year student here in Kuoh Academy, and a member of the occult research club." Rias introduced as Koneko notices Izayoi after Rias introduction of her.

"Izayoi-san." Koneko said as Izayoi raised an eyebrow on the discovery.

"The whole club knows you, Izayoi-kun. Even the whole school knows about you by now. Defeating a gang of delinquents, and saving a girl in front of the school, that triggered the rumors and the desire to know about you." Rias said with a smile, as Izayoi smirk at her.

"I never thought I would be famous in this Academy. Or even had everyone in the entire school wanting to know me." Izayoi stated as he sat on one of the chairs.

"Ara, what do we have here?" A voice said as Izayoi look towards the voice, as it reveals to be Akeno who walked beside the couch.

"It's nice to see you again, Izayoi." Akeno said with a smile, while Izayoi replied with a smirk.

"Well, it's nice to see you again, Akeno. Do you still want to guide me around the school?" Izayoi asked as Akeno's hands were twitching with electricity. "Am I annoying you?" Izayoi said with a smirk seeing the electricity covering Akeno's hands.

"Maybe..." Akeno said as she held out her hand in front of her, and immediately electric shot out of her hands and it was heading straight to Izayoi.

"Annoying, huh?" Izayoi said watching as five bolts of lightning were getting near towards him. Just as when the bolts of lightning were in front of him, he immediately back slapped it with his left hand, as the electricity disappear.

"Hmm... You're more stronger than I thought. Even if you're arrogant." Akeno commented as Izayoi smirked. "Well, I aim to please. Besides, I'm here to apologize for the guide you offer. I really don't want to guide around the school, it's just going to be boring for me." Izayoi stated as Akeno smiled. "I'm thinking the same thing. It's a surprise we share the same thought." Akeno said as Izayoi smiled his charming smile. The action made both Rias and Akeno's hearts skip a beat.

"Yeah. It's a surprise." He said as he sat on one of the chairs, while Akeno went to make tea.

"First off, welcome to the occult research club, Izayoi-kun." Rias greeted as Izayoi nodded in appreciation.

"So I take it, you're all devils?" Izayoi asked.

"Very good, as expected of you, Izayoi-kun. I know there must be something about you, if you know that we're devils." Rias said as she graced him with a gentle smile. "Yes, all of us are devils." She answered.

"Tea?" She asked as Izayoi nodded, and Akeno placed a cup of tea in front of him.

"Thanks." Izayoi said as Akeno wore a surprised look. "Ara, ara. I never knew you were such a polite man, Izayoi." She stated as Izayoi picked up the cup of steaming water, lightly blowing on it before taking a drink.

"This is good." Izayoi complimented after taking a small sip. He then set the cup onto the saucer as Akeno smiled at him.

"Thank you." Akeno said to him.

Koneko who was sitting on the couch stare at Izayoi, as she stood up and walked over to him. She tugged at his sleeve which got his attention, as Izayoi turns to her with a raised eyebrow.

Koneko then grabbed his hand and put it on her head, as Izayoi realized that she wanted him to pet her like last time. "You want me to pet you?" Izayoi asked as Koneko nodded cutely as Izayoi smirked, petting her head with hand, while Koneko purred in satisfaction.

"Looks like one of us has gotten quite near to you, Izayoi." Akeno comment as Rias look at the two, hiding a frown from appearing on her face.

"Anyway, is there anyone else in your club?" Izayoi asked as Rias looked at him and nodded.

"Yes. There is. He is now bringing a new member along." Rias said as Izayoi raised an eyebrow. "A new member? Who?" Izayoi asked.

"Woah..." Issei said coming inside with a blond haired boy beside him. Izayoi noticed him as he sighed.

"Not him again." Izayoi said under his breath while Issei who look around finally notices Izayoi. "Hey, you're the one who punched Yuuma-chan." Issei said as Izayoi ignored him for a bit, and turns to Rias. "So, he has a sacred gear?" Izayoi asked as Rias nodded.

"You remember her right? Yuuma-chan? Do you remember her? I talk to everyone but they can't remember who Yuuma-chan is." Issei exclaimed as Izayoi thinks for a while.

"Yuuma-chan..." Izayoi mumbled as Issei expectantly look at him. "No. It doesn't ring any bells. But is she a black haired girl?" Izayoi asked as Issei furiously nodded. "No. Still doesn't ring any bells. How about you asked someone else?" Izayoi said hiding a smirk, while Issei deflated from Izayoi's answer.

"Are you kidding me?" Issei mumbled as Izayoi rest his head against the chair while Koneko sat on his lap, her head on his chest. The blond haired that was standing behind Issei walked over to Izayoi.

"It's nice to meet you, Izayoi-san. My name is Yuuto Kiba." Kiba said as he extend his hand towards Izayoi, to which he accept by shaking his hand. "So, you're one of the member of the occult research club?" Izayoi asked as Kiba nodded.

"Well, it looks like everyone is here. If you don't mind me, I'm going to take a bath. Then, we'll discuss about the events earlier for Issei." Rias exclaimed as she walked over to the bathroom, and closed the curtains.

"Wow..." Issei comment as he saw the body outline of Rias behind the curtains in the shower. Izayoi sensing that Issei was looking at Rias, he picked up a sugar cube that was on the desk in front of him, and threw it at Issei with a flick of his finger. "Don't look you sick perverted boy." Izayoi said as Issei look towards him, but he didn't noticed the sugar cube travelling towards him in light speed which he didn't see at all, until it hits him on the head and then propelled him across the room, knocking him out cold.

Kiba, Akeno and Koneko who watches the act had their eyes widen, by the show of strength from Izayoi. "Ara, what a surprising act of strength there, Izayoi. I never thought that you had that much in you." Akeno comment with a lick of her lips, impressed by the display of strength from Izayoi.

"Well, somebody has to knock some sense into that boy." Izayoi exclaimed with a grin, pointing his hand towards the knock out Issei.

"But Izayoi, you're a pervert too, right?" Akeno said as Izayoi smirk. "But I'm not that sick of a pervert like him." He said pointing his hand at Issei. "Why do you ask? There must be something in your mind to ask that question." Izayoi stated as Akeno smiled.

"There is not. I was just asking to confirm a question I got. That's all." Akeno exclaimed as Rias gets out of the bathroom, with her new set of school uniform. "What's going on in here?" Rias asked as Izayoi pointed his hand at Issei who was knocked out cold by something.

"Izayoi..." Rias said knowing that it was him who would do something like that to Issei and she knows that he was the only one who would have done something like this. "He was looking at you while you bath, like a sick perverted boy. Although I am impressed by the display of your body and curves..." Izayoi said with a sly smirk while Rias blushed by his perverted words.

"So you admit that you're the only one that can see Buchou like that?" Akeno asked as Izayoi smirk.

"Yeah." Izayoi simply answered, as Rias's cheeks turn pink.

"Well, let's get this discussion over with. I want to get some sleep after this." Izayoi said with a yawn.

"But somebody has to wake up Issei." Kiba said as Izayoi sighed, picking up another sugar cube and throwing at Issei again in light speed. The cube instantly hit Issei immediately waking him up as he look at everyone.

"W-What happen? I remember that something hit me awhile back. And it hurts!" Issei exclaimed rubbing his forehead furiously to make the pain go away.

"Pay attention." Izayoi said as Issei look at him and then Rias, who nodded at Izayoi.

Rias walked away from Izayoi and strode to the center of the room. "Alright, everyone. Today, I would like to introduce our newest member, Hyoudou Issei-san." Kiba, Koneko and Akeno all clapped for a while before eventually stopping, Izayoi merely focused his attention at Rias.

"As you all know, we Devils have been in a war with the Fallen Angels since ancient times. We have been fighting over the possession of the Underworld, also known as Hell in the human world. The Underworld is split into two areas of the Devil and Fallen Angel. The Devil forms a pact with humans and receives their sacrifice and increases their strength. The Fallen Angel on the other hand controls humans to eliminate Devils. And here, the Angels come to destroy the two races on God's order. So the war is split into three groups: Devils, Fallen Angels and Angels. This has been going on since ancient times."

Issei timidly raised his hand, his eyes nervously darting from Izayoi to Rias. "Um... Rias-senpai... That kind of story is hard to take in by a normal student like myself. Is this what members of the Occult Club do?"

"Well, it depends..." Izayoi suddenly raises his voice on to answer, as Issei turns to him. "Do you want to die?" He said as Issei stared at him in confusion. "Because those Fallen Angels are here in the human world to kill you. They are assigned to kill you. So, if you want to live, you might as well believe the story to be so." Izayoi said as Issei stared at him horror. "So do you get that in your head?" Izayoi asked looking at him, with mean looking eyes.

"H-Hai! S-Senpai!" Issei said with thoughts of him dying before the Fallen Angels.

"Rias, you can continue from here." Izayoi said as Rias nodded.

Time Skip

"That's it for today. We'll meet again tomorrow." Rias said as Issei rubbed his head, trying to slowly process the history between Devils, Fallen Angels and Angels.

Then, Issei realized something, "Rias-senpai, how come I'm still alive?" He asked as Rias held out a card.

"You summoned me from this flyer moments before you died. But Izayoi-kun is the one who summoned me, that saved you." Rias said turning to Izayoi, who had his eyes closed while he sleeps.

"Izayoi-senpai?" Issei said turning to look at the sleeping Izayoi.

Rias nodded, "We're devils." She said as she then unfurled her devil wings, shocking Issei.

"Wha-" Issei backed away in fear. "We're the same, Issei." Rias said as Koneko unfurled her wings, followed by Akeno and Kiba. Issei then look behind him to see that he had wings like everyone.

Issei turns to Izayoi who was sleeping peacefully. "How about Izayoi-senpai? Is he a devil too?" He asked as Rias walked over to Izayoi and put her arms around Izayoi's neck.

"No, he's a human. But he has powers that is far beyond that of human capabilities." Rias said with a smile, looking down at Izayoi.

Rias then unwrap her arms around Izayoi's neck, "Demons collect power by forming contracts with humans and receiving compensations for it. Nowadays, no one manually draws magic circles to summon demons, so we just hand the circles out to potential contractors." Rias explained.

"We usually have familiars do it, but as a servant demon, you need to learn the basics." Rias said as Issei packed in his bag for his deliveries as a servant demon.

Time Skip

"The deliveries done!" Issei said as Rias who was done bathing, sat next to Izayoi who was still sleeping. "I have one more task for you. Koneko received two summoning requests... So, I'll let you handle one of them." Rias said laying her head on Izayoi's shoulder.

Issei turns to Koneko who bows at him, "Thanks for doing this." She said in a monotone voice.

Issei then head to the summoning circle that Akeno prepared for him, as his right hand had a carved seal on it, courtesy of Rias. He then stepped on the circle for his first contract. The summoning circle glowed, engulfing Issei. After a few seconds, the summoning circle disappeared, leaving only Issei in the middle. "Issei, looks like you can't jump" Rias said Issei look at her in shock. "Yeah, and looks like you have to go there by bike." Izayoi said with a yawn, after waking up from his sleep.

"You're awake, Izayoi-kun?" Rias asked turning at him.

"Yeah. I got a nice dream of someone wrapping their arms around me. It was nice." Izayoi said with a smirk, as Rias blushed, recalling that she wrapped her arm around him earlier. "And then i dreamed of someone laying their head on my shoulder, and she was only wearing a towel." Izayoi said looking at Rias, who blushed again.

"Issei," Izayoi said catching Issei's attention. "Don't you have a contract to go to?" Izayoi said as Issei suddenly recalled that he had just given his first contract as a demon. He then hurriedly runs out from the club and rode his bike to the contractor who summoned him.

"Y-You were awake, this whole time?" Rias said as Izayoi stood up from the couch and stretched himself.

"Maybe... Maybe not. But i enjoyed my time here with this club." Izayoi said as he turns around to leave. "I'll be visiting tomorrow. This club might be worth joining after all." Izayoi glanced at Rias behind him, and with a smirk, he vanished, surprising Kiba of his speed.

"Buchou, is he really a human?" Kiba asked.

"Yeah." Rias said with a nod, as she stared at the spot where Izayoi vanished.

"And I think we just got ourselves a new member." Rias said with a smile, but then a frown appear on her face.

"And I won't let any Fallen Angels take away my Izayoi-kun." Rias said under her breath with narrow eyes.

Next morning...

"Why are school invented for anyway? This will be a boring day." Izayoi said under his breath as he walked alongside an alleyway.

"But, maybe I'll get something fun to do in the club instead." Izayoi said as he heard someone falling.

He turns towards the noise, and he was greeted by the sight of white panties and a nice view of the person's butt. Izayoi held a hand under his chin, examining the view with his eyes.

"This isn't a bad morning to begin with." He said with a smirk, looking at the person's panties a little longer, before the said person stood up from her position and switched to sitting on the ground.

"A nun?" Izayoi said as he noticed that the girl wore a nun's outfit. A cross could be seen on the nun's hood, above the girl's head.

Izayoi suddenly looked in front of him, ignoring the blonde haired girl as he saw that there was a red teleportation circle. He raised an eyebrow at the portal, wondering if 'he' is summoning him.

"What have you got in your mind, Sirzech? To summon me at a time like this?" Izayoi asked himself as he slowly touched the portal, to which he suddenly disappeared without a trace.

The blond haired girl who witness the scene, held a hand to her mouth in shock.

Underworld

"Where am I?" Izayoi asked as he suddenly teleported to the Underworld, but he wasn't in the same place as when Sirzech always summoned him to.

He looked up as standing before him was a huge castle, with a huge symbol on top of it, looking like a necklace and it was blue in color.

"The Sitri Clan..." He whispers as a frown appear on his face.

"Sirzech..." He said under his breath, as he looked up at the castle in front of him.

"Well, since I've been teleported here. Might as well take a look inside." Izayoi said with a smirk, gazing up at the huge castle.

Well, how about that, everyone? Do you like it? Love it? Or... whichever suits you. So, I've been reading the recent reviews that you sent me, and some of them, I don't know if I should answer or not. But I'll try to answer, so first up... from Ryuuto Raizel. I will be honest with you, and don't hate me for this. But I don't plan to put Black Rabbit (Kurousagi) in this Fanfic. I'm sorry, but I think it's just too much for me to write. But I hope you're still going to support me.

And second... Asuka isn't going to appear in the story. I put her in chapter 2 as a short story, that's all.

So, I hope you all understand. And support my Fanfic. Stay tune for the next chapter. I'm going to go, Ja'ne! ArtLotus out!
