3 months goes by, the unwanted, long intense commotion between Issei's relationship with the heiress of the Lucifuge Household, Grayfia Lucifuge and the Old Devils of the Council has ended with the help of 4 Maous who had took sides with Issei. Grayfia and Lucy along with Murayama, Katase, Saji and Reya Kusaka living together in his newly renovated house. Rias and her peerage also living in his house.
He set up a protection barrier around his house which will only allowed people he deemed friends and allies to get through. He were having lunch break on the rooftop with his girlfriends (excluding Grayfia and Lucy) and Saji as Rias and his fellow peerage having lunch in the clubroom. The rumors about him in Kouh Academy being a pervert is ceased to exist as he has revealed his true appearance which earned him a title 'Cold Prince' due to his coldness nature.
Issei: "Well the rumor about me being a pervert is no longer spreading yet... now the girls admire me despite my cold nature which earn 'Cold Prince' title."
He said with a sigh. Saji laughs at his bestfriend's misfortune.
Saji: "Well, good luck with that. 2nd Prince of Kouh, many girls want to get their hands into your pants so be careful. The Student Council can't save you everytime you're in pinch."
Issei: "I do want bit chaotic life but not like this... urghh... what did I do to deserve this?"
He groans in annoyance. His mates giggles at his frustration remarks.
Asia: "Calm down Ise-san. I'm sure Kaori-san and Yui-san will protect you from those girls, I'm sure Kusaka-san and I will be too so rest assured okay?"
She said while pats his back.
Murayama: "Hell yeah! No one laid their hands on our Ise-kun!"
She shouts.
Katase: "You're being loud, Kaori!"
She gave her a light smack in the head.
Murayama: "Oww... that's uncalled for, Yui.."
She rubs the back of her head.
Reya: "Calm down guys. We have his back so no need to be so optimistic."
She said calmly.
Issei: "Thanks girls."
He smiles softly at them.
[Few hours later]
After Issei and his mates, bestfriend, parents along with Rias and her peerage members having dinner, they returned to respective rooms excluding Issei and Grayfia who heads to his office to discuss few things.
[To Issei and Grayfia in his office]
Issei: "Did you and our baby doing well, Fia-chan?"
He asked her with worries in his voice as he sat down on the chair.
Grayfia: "We're doing fine, you worry too much, my dear Ise-kun."
She replied with a smile.
Issei: "Of course I'm worry. There's no way I wouldn't be... after what those old bastards trying to do to you and our unborn child."
He said sternly as he bit his thumb. Grayfia walks towards him and sat on his lap, resting her head on his chest.
Grayfia: "I'm truly happy for that, Ise-kun. You showered me with tons of love, I'm glad that I met you those years ago."
She smiles softly as she remembers those days.
Issei: "Me too, Grayfia. It was the happiest day in my life."
He said as he kissed her head affectionately.
Issei: "Anyway... I got an unwanted stray exorcist to get rid off. He causing trouble so far which I can't allowed that. I'll be back in an hour so you go ahead and sleep, you needed as much rest for our baby."
He added as he took her hand and kisses it.
Grayfia: "I understand. However only an hour, if you get home a minute later... no kissing or sex for a week, do you understand?"
She looks at him as she poke his forehead. Issei giggles at her joke.
Issei: "No worries, it won't even be half an hour to deal with small fries like that stray."
He said smiling. Grayfia stood up and heads to their room, leaving Issei behind.
[At the abandoned church]
2 exorcists went inside the church to meet with a priest here, unknowingly to them, the one they were waiting for is being tortured by Freed Zelzan, the stray exorcist. Issei currently walking in the street, knowing he will met the guy.
???: "The church is no longer functioning based on the mess here."
The blue haired exorcist said.
??? 2: "I heard that 100 stray exorcists were assembled here for some kind of ritual but due to unknown reason, the rituals were failure and those exorcists run amok before leaving."
The chestnut haired replied.
???: "In any case, that priest is kind of late. This is the place we're gonna met him?"
She asked as she removed the hood, looking at her partner who removed hers then looks at her.
??? 2: "There's no mistake. It because I used to live here with my parents! When I was a kid!"
She revealed the picture of her with Issei as kids in between of her fingers.
[To Issei]
He was walking in the rain.
Issei: 'Hades... I heard rumors about him hating Sacred Gear Wielders.. in that case, I will have to obliterate him. He poses a threat to us therefore he must be executed.'
His inner thoughts were snapped as he heard someone's voice echoed in the alley, and to his surprise, he encountered a priest who walking towards him before falling on the road and die.
Issei: "A priest?"
He looks down at the deceased priest then heard a footsteps so he looks up to see who it is.
???: "Ya ya, yaho! Look who it is. A damn devil."
He said while swinging the sword in his hands.
Issei: "Freed Zelzan. It is nice to make an acquaintance... is what I want to say but truthfully, it is loathsome to meet you here. It seems you still wandering around the town and caused unnecessary trouble here."
Freed: "I can't hold my tears for the touching meeting!"
He said with creepiness in his voice ended with bit laughter.
Issei: "You save me the trouble of looking for you so I shall express my gratitude to you."
He replied with a smirk.
Freed: "Nice to hear that! I'm bored killing priests for days!"
He swings the sword again as it radiates the light.
Issei: "Excalibur huh? I bet it's Excalibur Rapidly."
He said with a bit disdain as he feel kinda uncomfortable given that he's a devil.
Freed: "That's right! Nice timing! To express my gratitude as well your deduction, would you want to be the first devil scum to die by my EXCA-LI-BUR!"
He said creepily as he points the Excalibur at the devil.
Issei: "Welcome to try but if you land a single scratch on me that is."
He said with a savagely smirks on his face and continued.
Issei: "And I know your boss have the other remaining Excalibur he stole from the church. I hate to say this but..."
He instantly appeared before the stray exorcist and swiftly cut his head off then throw the excalibur in his pocket dimension.
Issei: "... you won't be there when he show up. Thank you for the gift."
He created fireball in his hand and fire it towards Freed, burning him into nothing but ashes. He then teleported back to his room and clean himself before joining his mates in bed.
