It's an early morning on Saturday and Issei begins to wake up feeling nauseous and runs to the bathroom to let it out. After he's done he looks himself in the mirror and sees that he has gone a bit buffer from his swimmer build and his hair had a new style to it with the side of his hair cut and the top left uncut and he has tattoos on his neck, both his arms covered in tattoos and his left chest as well having Demon and Dragons on them.
He goes back to bed but sees Moka and Asia with the only piece of cloth on their bodies were thier panties and their breasts out. Issei walked up to the bed and covered them and kissed both of their heads before getting freshened up.
Once he has finished Issei goes downstairs and he surprisingly doesn't see his mother but he saw his father in the same suit he wore on Open House and was staring into the fireplace while sitting on the couch. Gorou then notices that someone is in the room and turns his head to see his son.
Gorou: Ah!, Issei, you woke up. Come sit down.
Issei sits down on the couch opposite of Gorou and Gorou then looks at Issei in a serious manner.
Gorou: So you've awakened the Ink Demon.
Issei thought back to yesterday and remembers talking to the Ink Demon before everything became blank and he woke up in his bed and not fighting Vali.
Issei: H-How do you know?
Gorou: Bendy? You mind explaining?
Issei then sees black ink flowing out of his hands and Bendy's cute miniature version formed on the floor.
Bendy: Issei. You're father is the sole reason why I am still alive. If it wasn't for him I would've perished in that old studio and he sacrificed his body in order for me to survive and he has become a full Demon with no humanity.
Gorou stands up and his eyes glow red and an image of a giant Demon is shown levitating behind him.
Gorou: I've been having Bendy since 1973 and I was 39 at the time and I have been looking like I'm in my 20's for many years even though I'm technically 78 years old.
Issei was surprised at what he just heard from the two and so was Ddraig as he appeared as a red gem in Issei's hand.
Ddraig: So you already know of my existence and the supernatural?
Gorou: Oh yes and it's an honor to meet the Heavenly Dragon himself. The one who taught my son on many things I could've but you had it covered as soon as Issei came back with Moka all those years ago. So thank you.
Gorou bowed.
Ddraig: It fine, Gorou. And about yesterday?
Gorou unfurled 5 pairs of demon wings which shocked Issei a lot. His own father, being this powerful all this time was an absolute shocker to him and the wings disappeared.
Issei: How do I get rid of these tat's?
Gorou: Imagine them not being there.
Issei imagined it and the tattoos disappeared from his body.
Gorou: You see. The power of imagination is limitless.
Issei: Awesome!
Gorou: I've been thinking...
Issei turned to his father.
Issei: About what?
Gorou: Taking you to my territory to train your Demonic powers and abilities while the girl's take a vacation.
Issei: So you mean this whole summer Vacation that's coming up soon?
Gorou: Yes and it would be good to see what my son is made of. But that will be discussed later on, you may go.
Issei left with Bendy going back into his body.
Once he arrived back into his room and thought about many things and Moka was on the other side of the bed and Issei gently went into the bed and after he relaxed his body Asia rolled her naked upper half onto Issei and smiled at feeling the warmth that was Issei and he held her pale blonde hair with his fingers.
A few days later
Issei made a quick recovery over the weekend and many students looked at Issei like he's a changed person and when he came back to class and told everyone who he is they were all shocked and some girls had blushes on their faces when he would sleep or smile in class.
Later on when the school bell rung indicating that it was lunch time Issei would go to the O.R.C with Moka and Asia. When he entered he greeted everyone but was instantly hugged then fell on the floor with two weights on him.
These two weights were Akeno Himejima and Koneko Toujo who jumped on Issei and it surprised Moka and Asia.
Issei: Hey, what's wrong?
Akeno was the first to speak.
Akeno: We thought you were gonna die on us, Ise!
She cried out. Then it was Koneko who didn't have her monotone face anymore. She was crying as well.
Koneko: I don't want to lose you, senpai!
Issei held the two girl's heads into his chest and rubbed their heads.
Issei: I'm alright. Girls like you shouldn't cry and I resolved things with my Demon.
After Issei stood up with the two and sat them onto the couch he explained everything about who Bendy is, his history and how he is inside Issei's body as a host for the past 18 years.
Rias: On another subject, Akeno and Koneko suggested that they want to stay with you.
Issei: Since when?
He asked in confusion.
Rias: After the conference and also Azazel said that since you are the reason for them getting stronger they should stay with you.
Akeno and Koneko: Can we?
They looked at Issei with eyes of begging and... lust?
Issei: Alright, Girls, Welcome to the family!
Issei held his arms out and the two surprisingly kissed him on the lips. Akeno was first and Koneko last. They've fallen hopelessly in love with him.
Ever since Issei helped them in their training and when they would fight they would feel an attraction towards him and it began to develop into them touching themselves at night just thinking about him.
Akeno and Koneko: We love you, Ise~
Issei smiles and he looked towards Moka and Asia and the two were not jealous but happy for him and the girl's and joined the hug.
A few moments later lunchtime was over and Issei left the clubroom saying goodbye to everyone and headed to class.
Two weeks later
Summer break had arrived and all of the students were happy that they could take a break from school for a while and have taken time to either stay at home, go to their families and go on vacation to anywhere in the world. Akeno and Koneko were welcomed into the Hyoudou House and had been teased by Miki asking when will she get Grandchildren and it made them embarrassed for a bit til the Miki and The four girls began to talk more and more about kids and most importantly Issei Hyoudou.
A few hours later
Issei was at a train station with the O.R.C. Rias then takes out a card while anyone wasn't looking and walked through a wall leading to a staircase and a few moments later there a huge luxurious train that had the Gremory Symbol on the side that was as long as give bullet trains and the O.R.C went onto the train only leaving Rias and Issei outside of the train.
Rias: We'll be in the Underworld for a while and we'll call or my brother and the other Satans will call you if anything is an urgent matter.
Issei: Right. See ya then!
Rias: See ya! Rias got onboard and the train left with Akeno and Koneko shouting goodbye out of the windows towards Issei. He was gonna miss them but he had some other matters to deal with.
For example saying goodbye to his mates Asia and Moka and her familiar, Cerberus who has grown to be at Moka's hip and had become a bit more powerful and caring to Issei to the point that she even bit him but not too hard in frustration for not coming with him.
Issei: Don't worry, Cerberus. We'll see each other again.
The female hound licked his face and jumped into the other car with Miki driving and Moka sitting in shotgun and Asia and Cerberus at the back.
Miki, Moka and Asia: BYE!!
They drive off and as soon as they were out of view Issei and his father began to put their stuff into the Q7 and a few bags later they were done but Issei forgot his phone in his room and ran into the house to go fetch it.
As soon as he got it he was about to leave the house he felt an enormous amount of power radiating from behind him in pulses. A red gem formed on Issei's hand and he spoke in a serious manner.
Ddraig: What are you doing here, Ophis?
Issei: Ophis?
Issei turned around and a cute young girl with long black hair down to her hips and black eyes. Her ears differ from a normal human's as they have pointed tips, although her long black hair makes this feature difficult to notice.
Issei backed away from her on instinct and looked towards Ophis but she got closer and Issei stopped moving and pulled himself together.
Ophis: To answer your question, Ddraig. I'm interested in your host. If he were to join the Khaos Brigade and used my snakes, he can help me.
Issei: Help with what exactly?
Ophis: A world of silence. I would like to return to the Dimensional Gap that is my home... and reclaim that silence. That is all.
Issei: No, I won't join your group.
Ophis' expression never changed when Issei said "No" and closed her eyes.
Ophis: Such a shame. Very well then. I respect your decision, Black Dragon. We might see each other again.
Issei: We'll see...
Ophis disappeared from sight and Issei locked the house and left with his dad for his Demon training.
With Ophis
Ophis arrives at the entrance of a cave and she threaded for five minutes and she reached the doors of a huge mansion and entered it.
She walks into the lounge and she sees a huge Black Panther sleeping on a rug infront of a fireplace and a monkey sleeping on a couch.
Ophis: Kuroka. Bikou.
After that the black panther is surrounded by a purple magic circle and a a beautiful young woman with a voluptuous figure, long black hair with split bangs, and hazel-gold eyes with cat-like pupils and two cat tails.
Her attire consists of a black kimono, a yellow obi, a set of golden beads, and an ornately detailed headband. The kimono features a red interior and it is open at her shoulders, giving view to her large breasts.
The monkey was surrounded by a red mist and a young man with reddish-brown hair, brown eyes, and an athletic build.
His attire is an ancient Chinese armor that was used during the Three Kingdoms period.
Bikou: You just left 10 minutes ago.
Kuroka: Who did you see this time?
Ophis: Issei Hyoudou, The Heavenly Dragon, Black Dragon Emperor of Domination.
She said monotonously. The two were shocked especially Bikou since he had seen what a monster Issei was when he went to fetch Vali that day and took a few feet back.
Kuroka: What you so scared of, Bikou?
Bikou: I wouldn't call him a Heavenly Dragon, He's more of a Demonic Dragon. He nearly killed Vali at the Conference between the Three Factions.
Kuroka was intrigued at this and called Ophis. She looked at Kuroka.
Kuroka: Can you show me an image of this, Issei.
Ophis lifts up her hand and a light projects from her hand onto the White wall and the image of Issei appeared.
Kuroka took a spit take when she saw Issei's face and body and she looked again with a blush.
Kuroka: He's so hoooooot! If he could defeat our boss easily, he's the perfect candidate as a mate for me, nya!
Bikou: So what did ask him?
Ophis: I asked him to join us but...
Bikou and Kuroka looked at Ophis with anticipation.
Ophis: He denied my request and I respect his denial. If he doesn't join us it's fine but a shame... Where's Vali?
Speaking of Vali he walks into the room with new clothes and a scowl on his face.
Bikou: Hey, Vali.
Vali sat on the couch and inhaled fresh air the exhaled it.
Ophis: Vali, why do you look mad?
She asked him in monotone. He looks at her then closes his eyes.
Vali: It took me some time to make these scars go away from fighting my rival that day.
Vali rubbed the parts where Issei Hyoudou or should he say that monster that ripped of his limbs and looked back at his fight and saw the tremendous gap in their powers and he feels frustrated that he didn't win.
Kuroka: Too bad, Nya. One day I'm going to have his kittens!
She began purring and had thoughts of how many children she would have with him.
Vali: No you won't!
She was interrupted by Vali's voice of anger
Kuroka: And why is that, Nya?
Vali: Because I will kill him the next time we face each other in a real fight.
Albion looked at his partner mentally.
Albion: You wouldn't even have a chance, Vali.
Albion said in the Sacred Gear.
Albion: That means I'm the only Heavenly Dragon Emperor. We'll see each other soon... Demonic Dragon Emperor.
With Issei and Gorou.
Issei was asleep while his father was driving for the past 12 hours and Gorou stops by a tunnel that goes through a mountain. Issei wakes up from the sudden stop and sees that they stopped infront of a tunnel.
Gorou uses a demonic magic circle and the tunnel turns begins to swirls around and the inside begins to light up with varying odd colours and they begin to move again and they enter the tunnel.
A few moments later a bright light shone at the end of the tunnel and Issei appeared in a land that had a green sky, crimson sea going for miles and a barren land filled with dead trees making it the dead version of the Amazon rain forest.
Issei: Dad. Where are we?
Gorou: Another dimension a friend of mine created with a few others years ago.
Issei: Why is it such a barren land?
Gorou let out a sigh.
Gorou: Me and a Vampire named Issa Shuzen fought for over 2 years against a man named Alucard. He was a worthy adversary at the time but we'll never see him again.
Issei looked at his father with shock.
Issei: You fought against the Son of Dracula!
Gorou nodded.
Gorou: Oh and we're here.
Issei was confused.
Issei Where... (Looks out the window) Haaaaaaaaaah?!
Issei with his jaw cartoonishly on his lap and wide eyed at the gigantic Castle by the shores of the crimson sea that made it look amazing with the red lights but the red moon made it look even better.
While Issei was still in shock Gorou had already driven into the huge gates and parked the Q7 infront of the huge entrance of the Castle doors.
Ddraig had to get Issei out of his stupor and roared at Issei's ears.
ROAAAAAAAAAAAAAAAAR!!!!!
Issei: Ahhhh?! The hell?!
Ddraig: You were like a goddamn statue so I had to bring you back to the world of the living!
Ddraig shouted back at Issei and he got out of the car. The huge double doors opened and maids dressed almost like Grayfia but it was black and red. Then the maid spoke.
???: Welcome back home, Gorou-sama.
The silver haired beauty and the rest of the maids bow down to Gorou.
Gorou: Issei, This is Valerine, The Head maid of our Family.
He gestured to the silver haired woman.
Valerine: It's good to see the young master after 18 years.
Issei: Wait! She knows me?!
Valerine: Tohru. Elma. You may take their bags to their rooms.
The one who took Issei's luggage was Tohru who is a beautiful girl with long blonde hair with flaming orange tips and red-orange eyes with dilated pupils, and a buxom figure with large thighs and large breasts. Her attire is a maid outfit.
The other who took Gorou's luggage, Elma with short black hair, large breasts, blue eyes, and a long spiral unicorn-like horn on her forehead also wearing a maid outfit.
Valerine: Would you like breakfast, Gorou-sama?, Issei-sama?
Gorou: No thank you, we'd like to just settle get everything prepped for my son's training.
Valerine: Very well.
The maids headed into the Castle. Issei was expecting the castle to have stone walls and floors but no, the castle had tile floors that were as white as snow and the walls were painted in a nice red and adorned paintings, posters that had Bendy on them with a wolf, an angel with horns and many other characters from the show that the studio made.
The Castle has marble pillars that were in a beige white on every corner of the place and it had stairs that were made out of some kind of black rock with slits of gold in them.
Issei got hit with many kinds of smells from luxurious scents like lavender, coffee beans, Rosebush tea and spices from the kitchen.
Gorou then puts his coat on a hanger by the entrance and he walked toward a wall and pressed a button. The wall then opened and two metal doors opened up and Gorou went into the elevator and Issei followed suite.
A few days later.
Issei had gotten used to the place and loved it so far... until his training came along.
Issei was walking to the Library of the Castle with his father and Valerine.
Issei: Hey, Dad?
Issei said in a whisper.
Gorou: What?
He responded back in a whisper.
Issei: How old is Valerine?
Gorou: She's 30 years old. She's a descendant of Lucifer from a different universe.
Issei: Wait hold on! Valerine sounds almost like Vali's name but a female version... so... that... means...
...
...
...
SHE'S VALI LUCIFER!!, MY RIVAL!!!, BUT GENDER BENT?!?!
Issei's mind was in drastic confusion and panic in his mind but only shown as drops of sweat rolling off his face. Ddraig then told Issei some good news.
Ddraig: Issei, it's alright. This one is a full blooded devil and not a hybrid. She's not human so she can't have a Sacred Gear.
Issei: Holy shit! Thank Goodness! One thing I can say is that she has an aura of seduction similar to Akeno but tamed.
Issei exhaled and inhaled to keep him calm.
Gorou: What a shocker, right?
Issei: Yeah. Nice to know that.
Gorou, Valerine and Issei reach two huge double doors and Gorou puts his hand onto Issei's shoulder.
Gorou: You ready for your first trial?
Issei: Yes! Let's begin!
They enter the Library and Issei was instructed to stand on the pentagram in the middle of the room. Once stood on top of it Gorou began to use his blood as a sacrifice to operate the pentagram and it glowed in a bright yellow.
Gorou: Remember the conditions for this!
Issei: Hai!
Issei was surrounded by black swirl of ink and disappeared instantly.
Gorou: Let's hope this works out.
Valerine: Of course it will, My Darling~
Gorou immediately held her by her waist and flipped her into her back onto a table with his right knee in between her thighs and his right hand on her face. Caressing it gently.
Gorou: Now you've tempted me, woman.
He held her in a princess carry and left the room in a hurry to his quarters.
Gorou: Good luck, Issei.
