Chapter 82 - Onee-Chwan~

While inside the carriage, Issei was looking at the window seeing the nostalgic scene that had long been destroyed. Aika was taking photos of the place warning her about sharing it.

Katase and Murayama appreciate their phone is the latest in the market. Issei manages to replicate other phone products enabling his business to skyrocket even in the underworld it got popular.

"Even though I have my old memories, it's still breathtaking visiting this place again."(Aika)

"Yeah the last time I've been in this place was with my brother."(Le fay)

"As for me, it was last rating game fighting you Issei."(Jeanne)

"Ah that was great time. Cap Cao almost had me at that time."(Issei)

"Can you guys explain it to us? We were never gotten involve in the supernatural unlike Aika who for some reason married Issei."(Murayama)

"I can't believed that I live in ignorant for so long…"(Katase)

"Do you guys know chest?"

Issei had free time to explain the Rating games and how it is played. He wasn't planning in participating in rating game anytime soon as his power eclipses everyone else even Rias doesn't plan on competing as she was already satisfied with her life. Though, doesn't mean she'll tarnish the Gremory name.

She still planned to make name for herself and the Gremory household. Issei chuckled when imagining themselves competing in a rating game. It would be one side massacre and Rias was already stronger than her brother.

Few minutes had passed and they finally arrived at the gate where Ajuka was. It was simple facility for his research but had thick magical barrier preventing anyone from sneaking in. It was expected when the genius had many fail safe in countering and fighting enemies along with vital info about his research.

"If you pleased follow me, Ajuka-sama is waiting for you."

Upon getting out the carriage, Issei already sense the product on helping transform his lover. He was excited to make his lover even stronger than before since they had met a wall in their training.

Following the servant, Murayama and Katase was in awe how the placed looked like Victorian interior with many paintings and magical torches while Aika remained neutral since she had been exposed on this things.

Few seconds walking down the hallway Issei rode an elevator then the servant pressed it getting to the lowest level. Afterward, walked on a long hallway until arriving in a certain room.

"Ajuka-sama I had brought them."

"Let them in."

Before the servant could open the door a blur pass by and hugged Issei tightly while rubbing her faces all over him. Fortunately, he was tough enough to remain standing or Issei would have ended up on the ground. Not it would hurt him though.

"Ise-tan I miss you so much! Where so-tan!?"

"Hahaha I miss you too but can you calm down."

"No, I hadn't gotten my dose of Isseium!"

Issei warily smiled while the leviathan smothers herself to him. He turned to looked at Ajuka who was walking toward him smirking.

"So the Maou of Satan had finally arrived."

"Sheesh, that title makes me remember the amount of paperwork I had to finish…."

"Hahaha well come in I had wanted your opinion on the product. Though, this is the best I could do using my calculation."

Issei nodded following Ajuka along with his lover to his lab that contains countless research and materials. He could see that Ajuka was trying to improve the evil pieces and even prepared king pieces which dramatically increased someone's demonic power.

He already given Ajuka information in making Super class devils with the info from Koneko's hairpin. Though, Issei warn ajuka that if it was used to suppress other faction then he wouldn't hesitate to kill them. Thankfully, Ajuka plan to put fail safe that easily kill those that turn super class devil.

Issei knew he was breaking balance in the supernatural world but it would be all meaningless if they are all dead.

"What does thing do?"(Aika)

"Careful now, it might be dangerous if you get too close."(Ajuka)

"Ah sorry I couldn't help myself hehehe."(Aika)

"I'y excited to see the tools that can turn us into a dragon!"(Murayama)

"Wait if I turn in a dragon will my breast grow bigger?"(Aika)

"I think it won't only just make your breast bigger but transform into mature and prime state."(Issei)

"Wow! That sounds amazing!"(Katase)

"Yup! But not only that, I can also change my appearance I whatever want."

Issei quickly shape shift into a child form of himself along with his clothes causing his woman eyes to sparkle while Serafall hugged him even tighter.

"So cute~! Stay in this form a bit longer, ise-tan!?"(Serafall)

"Awww Ise-kun is so tiny~!"(Jeanne)

The rest of agrees somehow awoken a new fetish. Issei started to regret transforming but let it be since they are having fun, he wouldn't even mind. Ajuka trying to hide his laugh seeing Issei carried like doll.

"Ah here we are."

Ajuka presented cased towards Issei then upon opening could already sense the aura of a dragon. It was a simple dagger with intricate blade branching. The dagger contains a massive amount of Issei blood along with enchantment that provide certainty.

Issei took the blade and felt hi instinct that if someone is stabbed then they would turn into a dragon. He was sure the needed catalyst is that Issei needed to make that person his may before stabbing or they would die. It was convenient for dumbass trying to become powerful.

"Apologies for unable to make better tools but this is the best I could do with how complicated your request is."(Ajuka)

"No, this is enough. My dragon instinct is already certain it would work. Thank you for your help Ajuka. Here, this my research on weapons smith. You might be able to used to better improve devil life."

"Hahaha your always welcome. Perhaps we can have drink next time?"

"Sure sure I gladly take it."

Issei took the cased storing it to his pocket dimension before giving Ajuka ways in helping devil kind. He felt a certain obligation to help them not because some of his lover are devil kind but rather his bloodline. Afterward, the girls decided to explore the city with Issei in his shota form.

"Ah right! Here sera I made this for you."

Serafall tilted her head then saw Issei grabbed a magical wand couldn't helped but be excited. He smiled then handed the sacred gear towards her.

"Thank you thank you thank you, Ise-tan!"

"Hahah I knew you'd like it. Why not used balance breaker and see yo-"

"Balance breaker transform~!"

Before he could even finish, Serafall used the magical girl wand and began to transform with her clothes turning into pink and white frilly clothes. She looked exactly a magical girl with her demonic and magical energy gone through the roof.

"Woah! Beware big bad villain! Because Magical girl Serafall is coming for you~!

She made a peace sign while winking with Issei giving her a round of applause. Serafall asked about it's features from Issei who explain everything before she return back to normal as they will have a date around the city.

"But are you guys sure I should stay in this form while we have our date?"

"Of course! You look so cute in that form!"(Aika)

"Ise-tan try calling us onee-san!?"(Serafall)

"Onee-chwan?"

Everyone felt an arrow pierce their heart seeing the adorable Shota Issei. Serafall was nose bleeding and tainted while standing. He chuckled a bit how dramatic their reaction then turn to Jeanne who was praying while Murayama was quivering.

"Dear lord in heaven how can something so adorable exist."(Jeanne)

"Those that harm issei-chan innocent I'm prepared to slaughter anyone!"(Murayama)

"I think you broke them…."(Katase)

Issei warily smiled since the one speaking was having a nosebleed as well. He didn't expect this people are shotacon. Though, it's no denying that the situation was fun to watch. After calming them down, Serafall carried Issei like a doll around Agreas exploring the theme park. Those watching knew Serafall but none tried bothering her.

They ate ice cream along the way as Issei looked at them watching him eat. They were enjoying themselves far too much that the police would likely arrest them not for the facts it's serafall.

'Let me tease, Serafall a bit more.'

"Onee-chwan I want to ride that one."

""""Oof!"""

Triple hit combo that strike the three girls as they took a ride on the Ferris wheel. Needless to say they enjoyed their time with Jeanne moaning.
