Meeting

After some paperwork including some blood.

Me:"Oh yea, rias could you give me some of your blood including your members?"

Rias:"What for? Are you actually a vampire?"

Me:"I am not a blood sucker. Rias the way you guys get stronger is by training, its the same for me as well but I can also get stronger by fusing bloods of others to strengthen my own body. I have already fused with 2 bloodline."

Rias:"Isn't that too OP?"[I imagine rias won't really say OP but hey MY WARUDO]

Me:"Well I created it anyway just help me get the bloods, it will help me get stronger when I meet riser.

The next day.

6 days left till issei dies.

Me:"Derp derp derp kinda bored waiting for things to get started, Hm?"

??:"Get back here."

??:"So-tan give me a chance please?"

Sona:"No there is always a chaos when you go around the school, as the student council president I have a duty to keep things in order. Even if it's you onee-sama."

Serafall:"Ehh come on so-tan, oof."[Such a nice body]

Sona:"Onee-sama are you okay? Hey watch where your going."

Me:"Erh hi?"

Sona:"Oh you're the new student who just transferred in, what was your name again? Mango right?"

Me:"Yea, is your sister okay?"

Serafall:"Mo~ so-tan how can you forget about me. Hi hi mind helping me up?"

Me:"Sure btw why are you dressed in magical girl's clothing?"

Serafall:"I just like it."

Me:"Uh ha."

Sona:"Mango mind if you follow me, I need to talk with you about something."

Serafall:"What about me?"

Sona:"Onee-sama please follow as well as it may concern you."

Me:"Well looks like I have no choice, let's go."

Walking with the Sitri sisters caused a bit of commotion.

Crowd:"Woh who's that guy, the hell is that person wearing, isn't that sona's sister? Damn lucky guy."[Didn't know how to phrase it so I just smash them together, hopefully it didn't confuse you guys.]

Me:"So what did you want to talk to me about?"

Sona:"So what are you human? devil? fallen? angel?"

Me:"Wow straight to the point but I don't get what your talking about."

Sona:"You have this weird aura something that is hard to distinguish what it's origin is from."

Me:"Damn my aura again? Hell's wrong with getting attention because of my aura(Well not that i should be complaining about.)

Serafall:"Now that you mention, it does feel weird."

Sona:"Wait what do you mean by "again"."

Me:"Since it got to this point I might as well confess a bit. I know all about all of you guys, Sona Sitri the next heiress of the Sitri Clan after your older sister Serafall took the title of Leviathan, currently engaged to the heir of the naga clan. Btw all of this sound very familiar, the deja vu is strong here. Oh also Rias found out as well."[I couldn't find any reference to Sona's fiance so I ripped it off from DxD System In DxD.]

Both sisters: ....

Me:"Hai? knock knock anyone inside?"

Serafall:"I don't know what to say."

Sona:"So your saying rias knew but didn't tell me?"

Me:"Well yea I wanted to keep this a secret, in exchange I will be helping her with her engagement. How about I help you deal with your engagement and in exchange you be mine."[Yea these is how I will write it for now.]

Sona:"Sure but you need to be"

Me:"Smarter than you yea I know, why don't we have a little competition to see who's smarter? We will both give each other a question list and whoever correctly answer the most will win but the question has to be something that you know and can answer."

Sona:"Okay I like that but what happen's if you lose?"

Me:"I will help with your engagement free of charge."

Sona:"Then Let's make a deal."

Me:"Here's the contract stating whatever I just mentioned, as for the actually day it will happen I will also leave it up to you."

Sona:"You seem to be very confidant in yourself to let me do whatever I want. 'dripping blood and the contract' For the date let's set it to 2 days from now, I will have rias and her peerage and mine to spectate."

Me:"Sure then let's have your sister serafall to be the witness to this as well."

Serafall:"Okay I shall be the witness to this competition, So-tan you better win alright?"

Sona:"I will win Onee-sama."

Me:"Alright nice.Now then Sona, Serafall could you both give me a drop of your blood."

Both:"???"

Me:"One of the few ways I get stronger is if I fused your bloods into my body, I will need get stronger to deal with both of your engagements. Remember I am not a vampire."

Both:"Oh okay, here take the blood."

Small droplet of blood started to float towards my body and red lights started to shine from my body as well.

Me:"Nice I feel much stronger now.[SS Why didn't it hurt as much compared to when I fused with the kryptonian and saiyan bloodline?]

SS:"Your body was still normal back then and after you fused with 2 of the strongest bloodlines your body changed. The sitri bloodline when compared to both kryptonian and saiyan bloodline falls short no matter how you put it."

Serafall:"Wow looks likes magical, hey wanna"

Me:"No. I don't want to wear the costume."

Serafall:"Awe come on pretty please?"

Me:"No."

And this went on and on and on, till I just teleported out of there.

I know I used some parts from DxD System In DxD in my own story and I hope you can forgive me as both the reader and the author. I know eventually the author of the novel from DxD System In DxD will read this 'cough' hopefully 'cough' and I hope you can forgive me for using some parts of your story for mine without permission. I tried searching the web for sona's fiance via reddit or fandom and I would end up getting DxD System In DxD in my search result. Btw I have read DxD System In DxD it is one of the better fan-fic I have read and I do hope that the author can release the chapters more regularly 'cough' speaking of which 'cough I should also really start release more chapter myself but as I have mention previously I have been sick for give or take 4 days and I have exam coming in a week or 2, so please bare with me for my slow chapter release.

In the end sorry for the repeats i make as I like to re-emphasize a lot.
