Issei finish his cooperation with the maous in helping fix and prepare fro the future. He knew that his action would lead to cause and effects but understood it was way to do it.
Despite having the knowledge about future events doesn't mean it would result the same ways specially when he been interfering with time itself. Still he had made sure most important to him were safe and sound.
It was still early decided to visit his home and finally revive Irene who had been pestering him to hurry up. Issei obliged and teleported to his home where he was greeted by the empty room.
He went downstairs just to find Ophis and Crimsyn (Great Red) playing video games. They notice him arriving turn to look at him.
"Yo aniki its been a while since we last met!? Hows the devil doing?"
"Issei please stay and play with me. Baka-red been cheating."
"Hell nah you just suck at playing."
"Waah look Issei baka-red is scaring me."
Ophis monotonously said acting frightened and ran to hugged issei who only smiled while Great Red felt defeated by Ophis in getting their mate affection.
"Hey no fair I wanted to hug, Aniki."
"Hahaha well I miss you two but ophis where did you learn to act like this?"
"In the TV. I also learn from Aika about pleasuring male."
Issei pause for moment hearing the last word she said before. Ophis move her hands to his crouch feeling he quickly tried remove her hands surprising her causing a slight pout.
"You don't like it, Issei? Aika told me male like it??"
"Damn that perverted girl! No it was good but its not right to do it here."
"Wait Aniki let me do the same!"
"Stopped!! Waaah!!"
Crimsyn moved ophis on the way who pout once again while pushing Issei on the ground trying to remove his pants. He tried to stopped her before anyone could see them but it was too late.
"What's going on? Oh never mind good luck kid!"
Azazel was just taking a break from training his new student when he heard noise and arrived to see his favorite disciple doing the things he taught giving him a thumbs while Issei scream for him come and help him.
"Azazel-sensei what is-AAAAH!! What are you two doing!!?"
"Oh mind if we join?"
"Hey get off, my Issei!!"
Katase, Aika and murayama arrived to see Issei with Crimsyn (Great red) in the process of removing his pants. Issei felt like dying from the misunderstanding but it became worse when Murayama dash to him joining them.
_______________________________
After calming down everyone and explaining what happened. Issei joined them in the training ground where Azazel been helping training them. He scolded Aika about it but teasingly said it was to make sure she well educated. Issei annoyed but gave up since he would soon take her.
Murayama and her friends went and take breather letting Issei have private conversation with Azazel. They sat at the poach of a temporary home inside the training grounds.
"Hey sensei will Vali's group coming?"
"Yeah they would probably arrive soon. For now tell me did you gone and tell the Maou about it?"
"No not yet however I told them about Kuroka and I came from the future."
"I see you plan to tell in the faction meeting treaty huh? Are you sure about it?"
"Yeah it would be easier when all of us are present and able to cooperate for future plans."
Issei doesn't care about the magician since he would erect a more powerful barrier to ensure none would enter unless a dark apostle to arrived. He already prepared to fight when it happened.
He could have tell them one by one but it would create misunderstanding that Issei may hid information from them. Though he already broken this when be told about Kuroka but it was to make sure the Youkai faction not to wage war with Devil faction because of the Nekoshou extermination.
It wouldn't result in either side to fight therefore he let Sirzerch handle it. He trusted him enough to give suitable punishment for them if not then Issei would personally exterminate them.
"So how's Valerie doing?"
"She's been fine, right now she is in the mountain controlling her Sephiroth Graal. To be honest I don't even know if it's the same sacred gear in the previous timeline?"
"What do you mean?"
"Let's go."
Both them head to the far mountain where Issei surprised to find Valerie surrounded by eighty death knight kneeling in front of her. Issei could guess they were souls who been entice by Valerie.
"Issei-san you came to visit!"
Valerie ran up to him and hugging him while digging her fangs to his neck. She consume his blood greedily surprising Issei but let her be. Azazel whistle smiling then giving thumbs up.
"So tasty~"
"Glad you like it. Anyway how are you Valerie?"
"I've been great! I was training my sacred gear now able to control it better. I can change into any creature I want though its hard in making them stronger."
"Nah I think its amazing you are able to summon army of the dead. Still don't overwork yourself."
"I know but hey watch this!"
The death knight around them disappeared and went to her shadow remaining on standby. Issei knew that they are pure soul and no physical form which allow this death knight to perform better than reviving them. Each eighty death knight were as strong as middle to high class devil.
[A/N: essentially shadow monarch]
"I saw a dream recently about a white haired child calling itself vandalieu Zakkart and been helping me grow stronger."
"A dream? Vandalieu Zakkart??"
Issei raise an eyebrow about curious about the name as it was his first time hearing it. He glances at Azazel who shook his head.
"Yeah, he thought me that my Sephiroth Graal is only a medium and my true ability is different like this."
They flinch when they saw ghostly outline of Valerie who was glowing bluish tinge. It was similar to cloning but it was spiritual form. She was essentially separating her spirit from her body.
"He told me this is out of body experience and I can perform multiple task at the same time."
Issei was surprise both spoke at the same time. Valerie explain about her dreams about her encounter with this unknown person and showed the ghostly clones reshaping the spirit then solidifying it able create weapons or extra appendages for offense.
"Why tell me now? You should have inform Azazel first."
"Sorry but vandalieu told me that once I will only tell someone when your present."
"*sigh* anyway do you know what he look like?"
"He looked like a white haired child around ten with red and purple."
"Well that doesn't give us much."
"Oh he also told me about being an abyssal pure blooded vampire which gave me boost over soul and blood manipulation."
"Hmm I don't know why his helping us but we cant do much against him. As long he doesn't hurt you."
"Actually Vandalieu was fun talking to."
"I see. Anyway Valerie can you do me the favor now?"
Putting aside the unknown extra, Issei focus at another task which is reviving Irene. It was time for her be free from the prison given by God of the bible once again.
"Oh of course! I'm happy to help you."
"Alright. Irene are you ready?"
[Are you ready for the time for your life?]
Issei then told Valerie in what to do. After getting Irene soul from the boosted gear making sure they were still connected then enormous amount of energy burst causing them shield their eyes but gradually the smoke cleared revealing woman.
She had long crimson red hair braided to the side wearing a large witch had and skimpy outfit that accentuate her body. The woman smiled then stared at Issei afterwards swiftly move giving a passionate kiss greedily suck his tongue.
Their lips departed that made valerie blush from the erotic display but was a bit jealous. Meanwhile, Azazel was giving a proud smile.
"I told you I would devour you once I gain my body."
[The hell is going here!?]
From that multiple people arrived at the scene unfolding. Issei recognize them immediately specially that voice.
"So albino the bitch is here."
