Riser Phenex

From the magic circle a man having short blonde hair with dark blue eyes wearing a blazor and a white shirt inside with pants of matching color of his blazor and black shoes.

Riser :" Hello, I am Riser Phenex, and I am the Fiance of Rias Gremory "

Rias :" I don't accept you my fiance."

Riser :" It is decided by our family so you can't do anything about it."

Issei :" Hello, I am Rias' boyfriend and her future husband."

Hearing my introduction all of them were shocked as it was a proposal for marriage to Rias but Riser had veins appering on his forehead as he said

Riser

Riser :" You lowly human, you want to have my fiance.I will kill you"

Issei :" I already have her to me."

Issei :"And from your spies who spied on me from the day Grafiya and Sirzechs appeared here you should already know about it"

Hearing this he just gritted his teeth as it was true that he knew the reason why Sirzechs appeared here at that timefrom his spies but what he doesn't knew was about my full powers as I never exposed it in front of his spies. When he was going to attack me Another magic circle appeared from which Sirzechs and Grafiya appeared as they already detected Riser's presence.

Sirzechs :" Riser, What are you doing here? it's not the date of rating game or engagement "

Riser :"what are you saying? my future wife is with another man and I should just see all of this"

Sirzechs :"It is not decided that she is your wife until the rating game so you should wait until that."

Riser :" I don't care but he has to die"

Issei :" Ohh you think you can kill me? "

Riser :" of course what can a human like you do?

Issei :" Ok, if you want to kill me, how about we have a death rating game"

Riser :" Humph do you even have a peerage "

Issei :" Don't worry about it as I alone will be able to kill you even if you have your peerage"

Riser :" what a cocky person."

Issei :" Do you dare to accept my challenge?"

Riser :" Ok I accept and let's see how I will kill you"

Issei :" Then Sirzechs I want to have a death rating game with him"

Sirzechs frowned and said

Sirzechs :" Do you really want to? "

Issei :" Yes, can you arrange it. So that no one can interfere in our match"

Sirzechs :" Okay Two days later Grafiya will pick you from here and your match will be in underworld"

After this Sirzechs with Grafiya and Riser disappered with Riser looking at me with disgusting eyes. As they disappeared Rias said

Rias :" Issei, you didn't have to do that "

Issei :" he was calling you his future waife and was having dirty thoughts about you and I should just let him go? "

Rias :" But you can't kill him"

Issei :" why, just because he has phenex blood"

Rias :" you know about it's effect? "

Issei :" Yes, I know and I have my ways to deal with it"

Akeno :"Arara Darling, don't worry us in between match "

Kuroka :"Akeno you already know about him, so why are you still worried Nya~"

Koneko :"Sister, is he really going to be alright? "

Rose :" yes Koneko, even if there are 10s of Riser they will not be harm him"

Rias was going to say something again but was stopped by Rose saying

Rose :" Don't worry Rias, He surely has ways to deal with him"

Rias :" Sigh... Om fine but if you have to promise me that you will not get yourself killed

Issei :" Ok,I promise, Now let's get back to our house saying this. we all went to our house as I was talking to Jen in my mind

"Jen, is there a way to deal with his immortality"

[yes Issei, you can burn him instantly but for that you will require special Heaven burning fire which you can't use now ]

"So that means I can't kill him now"

[No,you can kill him but that will require a High-grade teleportation portal.With that you can teleport him to a star which will kill him. He wouldn't be able to heal himself as he will be burn to ashes instantly and if he can revive then again he will be burnt immediately.]

"Ok but one for me "

[ It will cost you 15M SP, Do you want to buy]

He didn't have to worry about SP as he had much of them due to his girls and killing all the stray devils. so he immediately said

"Yes buy one "

[Congratulations Issei for buying High Grade Teleportation portal ]

As I was talking to System we had already reached to our house and Sona's peerage was already there.

Sona :" Rias Tell me why did Riser come here? "

After which Rias told them about all the things happened at ORC. Then Sona turned towards me and said

Sona :" Are you really going to fight his whole peerage alone?"

Issei :" That won't be a problem. It's just that Ddraig wanted to fight for so long, so I thought They will be good for a fight if they are in a team."

Tsubaki :" But you should know they are not weak"

Issei :" Ohhh, Are you worrying about me sweetheart?"

On my words Tsubaki got blished but Then Tsubasa said

Tsubasa :" Yes, we are worried. After all you are our boyfriend."

Issei :" Ok, Don't worry all of you I have plans for fighting them, Now let's get some bath. "

Saying this I pulled Sona and Shuri who were near the bath to which Sona blushed knewing what is going to happen but Shuri just giggled while others followed us.

Asia also followed us but didn't joined us in those 'activities'. I think she still have something in her mind which is stopping her to accept her feelings fully. Murayama, Katase and Kiryuu also didn't join us.

They have started living with us after getting permission from their parents. Their parents were shocked seeing and talking me thinking how their daughters got such a handsome and gentle man in just few days of high school.

After two hours of bath we continued our 'activities' in bed while those four went to their rooms.
