Chapter One- I am finally back Onii-san!

It was a cloudy morning as the bright smiling sun is hidden behind grim grey clouds. Issei and his entire family were waiting infront of one of the airport terminals. Issei and his parents were eagerly waiting while Rias and her peerage were patiently waiting on one of the seats.

"Finally he's coming back. After 6 years he's back." Issei said as he had a flashback.

Flashback(Last Night)

Everyone were sitting in the living room talking about their fighting strategies and how to improve their individual powers. Suddenly the phone beside the table rang and Issei picked it up.

"Hello?" Issei said.

"Hello nii-san. It's been a while. How are you?" The unknown caller said.

"Nii-san? Wait! Don't tell me? Akiyo?" Issei said with happiness in his voice.

"Glad to be recognized after 6 years. How are you?" Akiyo said.

"I am fine! What about you? Oh wait! Stay on the line." Issei said.

"Mom! Dad! Akiyo is on the phone. Come on hurry!" Issei yelled with all his might

Suddenly Issei's parents ran inside the room and were fighting on who should dominate who to take the phone and talk to Akiyo.

"Nii-san you there? Do me a favour and put the phone on speaker." Akiyo said.

Issei quickly put the phone on speaker mode

"Hello mom! Hello dad! How are you?" Akiyo said.

"Akiyo sweetie how are you?" Issei's mom said.

"Akiyo it's been so many years! Where are you?" Issei's dad said.

"Wait up! Hear me out before you ask me anymore questions. I am coming back tomorrow on the 10am flight." Akiyo said.

"WHAT?! REALLY?!" Issei and his parents yelled in unison.

"Is that ok? I can change it to some other time or something….." Akiyo said in a meek voice.

"It's completely fine! But where have you been these past 6 years? We tried so hard to reach you." Issei's father said.

"I'm sorry. I swear I will tell everything after I come back. I promise. Alright. I have to go now. Bye." Akiyo said then he cut the call.

"He's coming back. I wonder how he will look?" Issei's mom said with tears of joy in her eyes.

"Obviously like me. No doubt!" Issei's dad said with a proud smile.

Issei smiled as a lone tear managed to leak out of his eyes.

Flashback(End)

Issei smiled as he had a slight reminiscence of the fated reunion. While Rias gave a small smile. Most of Rias's peerage including Gasper, Rossweisse, Xenovia and Irina were slightly confused from who this Akiyo person is. Other than Gasper they all presumed him another pervert considering he is Issei's brother. The very thought disgusted them as they might be having another pervert to deal with. After one hour everyone saw some activities near one of the terminals.

"Honey what time is it?" Issei's mom asked.

"10am. It's about time." Issei's dad checked his watch.

By this time Rias and her peerage got up and joined Issei's family. They saw that passengers lined the terminal one after another. A few minutes later, they saw a tall young boy with black hair that nearly covered his forehead while a few reached his eyes. He had blue eyes and his chest was broad. He wore a blue jacket with a black t-shirt underneath. He wore denim jeans and blue sports shoes with black stripes. His skin was light and he wore a black watch on his wrist.

"THERE HE IS!" Issei yelled and pointed in the direction. Everyone looked at the direction of Issei's finger.

"Are you sure that's him?" Rossweisse asked.

"Beyond sure! He will always wear that jacket. He has a record of never forgetting to wear it whenever he goes outside of the house." Issei explained.

The boy looked at their direction and waved as tears trickled down his face. Once he crossed the baggage checking he went to the customs office instead of going through the metal detector. After five minutes he came out and walked through the metal detector along with his baggage. Then he dashed in Issei's direction and Issei did the same. They clashed with a big hug as they laughed to their hearts content. Everyone came to them and then Issei's parents hugged him.

"It's been a while Akiyo-kun." Rias said as she hugged Akiyo tightly.

"I missed you a lot Onee-san!." Akiyo returned the hug.

"Ara Ara, Akiyo-kun, you became a handsome young man." Akeno giggled as she hugged him.

"Nice to see you too Akeno senpai. Uh? Can you increase the space between us please? It's kinda uncomfortable." Akiyo said with a faint blush.

"Ara Ara, is my size not enough?" Akeno giggled again.

"Stop asking me questions I don't want to answer dammit!" Akiyo retorted.

"How is your health Akiyo-san?" Asia said in a caring voice.

"Asia Nee-chan! I missed you so much!" Akiyo quickly grabbed Asia in a tight hug and Asia returned the hug.

"Akiyo became very cute." Koneko thought with a blush.

"Hi Koneko chan. You changed a lot." Akiyo said then hugged her as well.

"You too." Koneko said in a cute voice instead of her usual monotone voice and hugged him tightly then Akiyo pulled away.

They all took Akiyo's luggage and put them in a taxi's trunk, then they went to their own taxis with Issei and his parent's in the taxi with Akiyo while Rias and her peerage took another taxi. After a while they reached their house or mansion. Akiyo was dumbfounded at the sight infront of him.

"What is this place?" Akiyo asked.

"It's our home." Issei's dad said.

"THIS SEVEN STORIED CASTLE IS OUR HOUSE?" Akiyo was shocked.

"It's a gift from Rias's father. Did you know that he also does home decorating and real estate?" Issei's dad said again.

"He's a damn demon. That much I know. God, what happened these past six years?" Akiyo wondered.

After everyone went inside the house the first thing Akiyo did was run to his room, which he remembered to be on the opposite side of Issei's room. He saw that it was locked with a keycard lock.

"I made sure to take extra care of this room since it is your room also I took the liberty to personally decorate it." Rias handed Akiyo his keycard.

The moment Akiyo entered his room, he was feasted with a sight far more beautiful than anything he had ever imagined. On one side of the room was a shelf filled with all the latest and wanted games of all time and on another side was a smaller shelf with every type of gaming consoles available. His computer was what took his breath away. There were three wide screens, two large CPUs with the state of the art specs, a DSLR video camera standing on a tripod, a professional microphone standing beside it on another tripod, the latest RGB mouse, Mouse pad, keyboard and finally on the table is the latest RGB function headphones. On the middle of the room was a large bed and there was a round circular blue carpet below. On another side was a study table and on the table were five $50 steam gift cards.

"Nee-san…..I don't know what to say…..this is…." Akiyo was trying to find the right words.

"Do you like it?" Rias asked.

"No." Akiyo said with a serious expression. RIas was shocked to hear this.

"I LOVE IT!" Akiyo screamed like a little child. Rias smiled and was relieved to hear this.

"Oh yes. One more thing. Can you go to your Devitube channel?" Rias said. Akiyo went to the computer and went to Devitube. He was shocked to see that he has 500,000 subscribers.

"EHHHHHH?" Akiyo's scream reached at the end of the milky way. He never thought he would ever get this many subscribers. He looked at Rias and then at his computer screen then he got up and went to a corner and was inhaling and exhaling until he calmed down. Then he went to his computer and repeated the same thing almost three times. Rias can only giggle at his actions. Then Issei came and looked at Akiyo with a worried expression.

"What's with him?" Issei asked

"He couldn't believe that he is finally famous." RIas smiled.

"But how? I mean I released videos every now and then but I never released it on Devitube." Akiyo said as he checked that all his videos were posted on Devitube.

"Your channel is the most trending and inspiring channel in the underworld. The problem is…" Rias paused.

"What is it" Akiyo asked.

"There were very few videos of you and on top of that everyone from children to adults enjoyed your videos so much that they complain on why the videos take so long to make and upload. But the bitter reality is the fact that you didn't use Devitube and your fans are getting disappointed." Rias said. Akiyo felt extremely guilty and disgusted. He finally got his desired fanbase yet he couldn't satisfy them. This angered him a lot.

"Get out of this room." Akiyo said with a serious expression and tick mark throbbing on his head.

Rias silently went out of the room wondering what caused Akiyo to get angry. A few moments later she heard Akiyo's voice from the room.

"Hello everybody! My name is FreakShow71 and welcome to the first ever livestream sponsored by the Gremory family. I am so sorry for my slow uploads. I had too much on my plate, but that's about to change! For I am back and will be uploading videos in full force. So keep up with me. I am a fiend for not paying attention to such a loyal fanbase. You guys pushed me to tears (slight gasp). But in order to make up for it I am going to be making a giveaway….." Akiyo's voice blasted from inside the room.

Rias smiled and quickly went downstairs to inform everyone of Akiyo's debut to his lifelong dream. After 2 hours Akiyo's livestream finally ended as he got up from his computer and stretched his back. He looked at the clock and saw that it was 2pm. He went downstairs towards the dining room. He saw that everyone sat on the table and he silently went and took his seat.

"When will the giveaway begin?" Koneko asked.

"You actually watched my livestream? Wow, thanks." Akiyo was surprised and thanked Koneko, who blushed at Akiyo's reply.

"All of us watched. Seems like you still have it in you. Keep it up." Issei complimented.

"Thanks nii-san. That means a lot to me. Anyway the giveaway will begin 2 hours from now. I will give a link, so keep an eye on the community tab. Submit your name if you want to be a part of the giveaway. And if you are lucky you might win it. Results will be shown 2 days later." Akiyo replied.

"What game are you giving away and which game did you stream?" Dad asked.

"I streamed Rainbow Six Siege and I will giveaway Payday 2 to the top 5 winners. It's the least I could do to make up for my absence." Akiyo said.

Akiyo had his meal and then went back to his room. He laid down on his bed and stared at the ceiling while smiling. He never expected to have such a warm welcoming. He logged onto Devitube and was scrolling through the comment section. He was happy to see so many nice comments; mostly 'welcome back' and 'I missed you' comments. With the exception of a few hate comments he was nonetheless happy. Akiyo slowly drifted to sleep and started dreaming.

He dreamt that he was climbing a tree when he was 6 years old. He slowly climbed up and was reaching for the tree branch. But his footing slipped and he fell down. Akiyo sat up and was crying in pain as tears trickled down his cheek.

"Get up!" An unknown voice called to Akiyo. Akiyo looked at the direction of the voice and saw that it was a 7 year old Issei. Akiyo was still whimpering.

"Get up!" Issei said harsher tone. Akiyo got up.

"That tree is laughing at you. Don't you want to beat it?" Issei asked.

"But it's very tall. I can't climb up." Akiyo said in a helpless tone.

"You can do it! I know you can. If you fall down again, then get up and try again. Keep doing this and you will see that you succeeded in no time." Issei said. Akiyo looked up at the tree and was shivering a bit. Issei sighed and patted Akiyo on the head.

"This time I will help you." Issei said with a smile. Akiyo smiled and started to climb again. He was slowly going up but after a while he slipped but grabbed on. Akiyo yelped in fear.

"Don't you dare cry! You can do it! Come on." Issei encouraged. Hearing Issei's encouragement Akiyo put his footing once again and started to climb. He carefully reached for the branch and then hung on the branch. Akiyo pulled himself up and sat on the branch while cheering. He took two apples and was preparing to get down. He was climbing down but fell again halfway. As Akiyo was about to cry Issei came and softly hit Akiyo in the head.

"You did it! You beat the tree. Good Job." Issei complimented.

"But I fell down." Akiyo said in a teary voice.

"But you climbed up. Didn't you? You are very brave." Issei said. Akiyo smiled and wiped the tears in his eyes.

"It's thanks to you onii-san." Akiyo said.

"I was worried for you there. I thought you will fall down and cry again. But you didn't and I am proud" Issei patted Akiyo's head again.

"One day I will become as strong as you onii-san. Then you don't have to worry about me anymore. I will get up and try again. I won't cry. I promise." Akiyo said and Issei smiled.

"Race you." Issei said then ran. Akiyo ran behind Issei and slowly caught up with him. As he was running side by side he looked at Issei with adulation and vowed that he will never cry again, that he will become strong and independent just like him and he will never give up.

The dream ended and Akiyo woke up. He looked at his phone and saw that it was 4pm. He went to his computer and clicked on the Devitube community tab and posted the link for the giveaway. There was a knock on the door and Akiyo went to open it. He saw that Koneko was standing with his luggage.

"M-M-M-May I c-c-come i-i-i-in?" Koneko stammered shyly.

"Koneko-chan! You didn't need to do that." Akiyo said as he took some luggage from her and invited her to his room. He and Koneko placed his baggage on one corner and then Akiyo looked at Koneko.

"Thank you Koneko-chan. But you could've just called me. I would've helped." Akiyo thanked.

"It was no problem. B-B-B-B-B-But can I-I-I-I-I-I-I ask for a favour?" Koneko asked shyly.

"Anything. What is it?" Akiyo said.

'W-W-W-W-Will you p-p-p-p-p-p-pat m-m-my head?" Koneko was nervous.

"That's it? I was kinda hoping for the bigger one. But ok. No problem." Akiyo said and then started patting Koneko's head. Koneko turned beet red and she was struggling to hide a "meow", but to no avail as a faint "meow" escaped from her lips. Akiyo stopped and Koneko was worried about what Akiyo might say. But thankfully he was looking around his room searching for the source of the voice.

"When did a cat enter here? Did you hear it Koneko-chan?" Akiyo asked.

"No. I didn't hear anything." Koneko lied. But Akiyo still felt like something was off and decided to let it go for now.

"If you need anything else just tell alright? I still owe you." Akiyo said.

"No you don't. We are now even." Koneko said.

"Are you sure? I mean if you want I can do something else for you." Akiyo offered.

"No it's ok. Thank you for the headpat." Koneko said and then quickly ran out of the room. Akiyo was confused by her actions. "Was it something I said?" Akiyo wondered.

Koneko ran downstairs while cursing,"Ah! He's so cute. His hands were so warm! You are extremely useless Koneko! You are useless!"

Koneko ran to one of the couch then jumped on it. She screamed her heart out in frustration but she covered it with a pillow so it was muffled. Meanwhile, Asia, Xenovia and Rossweisse were wondering what caused Koneko to have such an outburst. Later Rias and the others came to the living room and saw that Koneko was lying on her belly with a pillow to cover her face. Rias slowly pulled the pillow away and saw that Koneko's face had an embarrassed look.

"Koneko? Are you ok?" Rias asked worriedly.

"I am completely useless. I ran out of his room just from one head pat." Koneko said in a monotone yet dead voice.

"You are alright." Rias concluded then sat beside her. A few moments later Akiyo entered the room and Koneko quick as lightning got up, fixed her hair and sat in an elegant fashion. Akiyo sat beside Koneko and she started blushing. Akiyo saw Koneko's blush and was worried whether she was having a fever. He put his hand on her forehead to check and immediately Koneko turned crimson red from embarrassment.

"Are you alright?" Akiyo asked.

"I am alright! Quit meoworrying about me." Koneko yelled. Akiyo was confused why she was acting like this. But decided not to talk about it now.

"Hey nii-san, you are in university now. Right?" Akiyo asked.

"Yeah. At Kuoh University." Issei said. Akiyo looked at Issei with a funny expression.

"They actually have a university by that name? Holy shit." Akiyo laughed and then said,"Alright! I have decided. I will enroll in Kuoh University."

"Good timing. They are handing out admission forms right now." Issei said.

"Cool I will enroll tomorrow then." Akiyo said. The rest of the evening and night went normally and finally it was time for Akiyo to sleep. He changed to his casual night clothes and laid down on his new bed. Then he covered himself with the blanket as he stared up at the ceiling once again. "It's good to be back." Akiyo said as he drifted to sleep.

A/N:- Well Guys that's about it for now. I am sorry for the lack of Ecchi and KonekoXOC fluff but don't worry it will happen in the next chapter. So until Next time. Bye!
