A/N: The Discord is live! I posted the link in my profile, so, check it out!

Y/N POV

I was in bed with Cecilia, as she was reading a letter she just received

Y/N: You're invited to a party? Who send it?

Cecilia: It's someone who keeps trying to take me, but i always refused, since i would never betray you

Y/N: Oh my god, come here you

I grabbed her shoulder, before kissing her deeply, as she kissed back

Wwe broke the kiss, as she smile and blushed

Cecilia:  Anyway, i think i will refuse. He is such a rude man with me, only seeing my body

Y/N: I'm going to kill him

I grabbed my guns, and started to walk toward the door, as Cecilia was trying to hold me

Cecilia: Violence isn't an answer!

Y/N: Yeah, because it's the ONLY answer

Cecilia: He is the current head scientist of Schicksal!

I stopped in my tracks, before looking at her, curious

Y/N: Tell me more about it

She smiled, before explaining to me what happened

Cecilia: 10 Years ago, the Scientist group had to find a leader for them, because you were not here anymore, and they couldn't make weapon without you

Y/N: So, Otto choosed this guy to take my place?

Cecilia: Yes and No. Otto wanted to disband the Scientist group at first, since they would be useless without you, but that guy, who claimed to make 'weapons greater than Y/N'

Y/N: Oh? What did he make?

Cecilia: Well, he just copied the Divine key, but they have less power, but still need to have a proper wielder

Y/N: Huh, seems lame. When is this party?

Cecilia: Friday, why?

Y/N: I have 3 days to make weapons far more useful than him, and more powerful

Cecilia: Why do you want to do that?

Y/N: That guy took my title, and tried to take the woman of my life, i'm not letting him go like that

She smiled widely, before cuddling to me, as we both fall asleep

Timeskip

I was in a lab that Theresa KINDLY give me, as i was drinking some coffee

Y/N: Weapons more useful and more powerful than divine key..... Huh, easy

I placed my cup on a table, before getting to work

Y/N: If i want to make them more powerful, i need to make something original......

The door slammed open, as Kiana walk in, excited

Kiana: Papa! Look! You can't fuse oil with water! But you can fuse sirop with water!

Y/N: That's normal, oil will never...... fuse...... with water......

Kiana: Papa? Did something happened?

Y/N: I KNOW WHAT TO DO!

She jumped at my outburst, as i smirk

Y/N: Kiana, what do you say about having new guns?

Kiana: Really?! My old one are getting weaker, and they don't shoot as fast as they were before, so YES!

Y/N: I'm going to make you new ones then! Tell Mei, Bronya, Fu Hua, Himeko and Midget to come and see me in 2 days, okay?

Kiana: Okay! Love you Papa!

Y/N: Love you too sweetheart!

She ran away, as i smirk

Y/N: If i can't make something different, let's upgrade the last version

Timeskip

In the end, i finished my work in a day, as i took the second day to test the weapon with Otto

Otto: So, you are telling me, that instead of having only one power, the weapons you made have every known divine key power?

Y/N: Yeah, it came to my mind when Kiana told me she discovered oil and water can't fuse

Otto: Just like that? I thought you have to think about it for a week or more, not because Kiana told you oil and water can't fuse. Anyway, i need to see it before i judge it

Y/N: Yeah, anyway, we should test the guns first

I took the guns, before i aimed at the target, and switched to the 6th key power

Y/N: Bang!

I shoot the target in the head, as it entire body disappeard, as me and Otto stayed silent

Y/N: ......

Otto: .....

Y/N: ..... I think i made a mistake by saying i'm going to give it to Kiana

Otto: You don't say

I took the sword i made from Mei, before switching to Judgment of Shamash power, and send a slash at the second target

Y/N: Swish!

Otto: Do you have to make every sound when you attack?

Y/N: Yeah

I didn't realize, but the target was gone too, turned into ashes

Y/N: It have less power in it, but, it's safe for the wielder

Otto: I must say, you impress me, even more than whan Joe showed me 10 years ago

Y/N: You thought i was inferior to this little shit?

Otto: No, but making copy of a Divine key is nothing to laugh about, i had to respect that

Y/N: Huh, anyway, let's go to the canons now

Otto: I'm going to a safe place first

Y/N: HONEY I HAVE A SURPRISE FOR YOU! BOOM!

Otto: Sometimes, he scares me....

Timeskip

The test were over, i finished the weapons, told the girls how to use it, and tell them to use it only as a last ressort

Kiana said she didn't care at first, but after a NICE talk with her, she aggreed :D

Me and Cecilia were going together, as she was wearing a beautiful dress 

Y/N: You look splendid, as always

Cecilia: Thank you dear, you look handsome as well

She kissed my cheek, before we stood in front of the door, a waiter standing in front of it

Waiter: May i know your name?

Cecilia: Cecilia Schariac

Y/N: Y/N Kaslana

Waiter: I am sorry, but Y/N Kaslana is dead, i will ask you to give me your real name

Y/N: No

Waiter: I see, well then Valkyries!

A group of Valkyries jumped behind us, ready to fight

Waiter: Dispose of that man, please

Valkyrie: Yes!

Y/N: Wait, i know that voice!

I turn around, and see the woman that asked me a weapon 16 years ago, before i took Sirin with me

Y/N: You're the Valkyrie that asked me for a weapon 16 years ago!

Valkyrie: M-Mister Kaslana?! It's really you!

She run and stop in front of me, and bowed

Valkyrie: I'm truly sorry for disrespecting you!

Y/N: Nah, it's all cool! How've you been since then?

Valkyrie: Well, i have advanced to a A-rank class, thanks to you. You inspired me, as i pushed beyond my limits

Y/N: It's good to hear! With you, i know civilians won't have anything to fear

She smiled, before i took Cecilia in my arms, and smirk

Y/N: I think you may know her, but this beautiful woman here is Cecilia Schariac, my wife

Valkyrie: O-OH MY! So it was true!

Cecilia: Hi

Y/N: Anyway, i would love to talk with you, but we have a party to attend! Keep up the good work girls!

Valkyries: Yes! Thank you very much!

We walk past the Waiter who was still in shock

Y/N: See ya buddy

We walked toward the main room, where we could see a lot of people dressed properly, and they all seems rich

???: Well, well, well, you finally decided to come, Cecilia

We turn to the owner of the voice, and see a middle aged man, smirking, and walking to Cecilia

Cecilia: Yes, it is nice to see you, Mr.Joe

Joe: Oh, no need to be so formal, i am yours after all~

Y/N: Yeah, no

Joe: Who are you, and who said you could come?

Y/N: I'm Y/N Kaslana, Cecilia's husband, and also the head scientist of Schicksal

Joe: Oh? The Head scientist? Well, i am sorry to tell you that, but Schicksal needed someone better than you, and they choosed me. I made weapons equal to the Divine key, after all!

Y/N: And he is barging about it even thoough it's supposed to be a secret.....

Joe: So, i will ask you to leave this party at once, we don't need old man like you here. But Cecilia, you can stay here, i will treat you better than this failure

Y/N: Oh, you shouldn't have done it

He blinked once, before Cecilia punched him directly in the jaw, sending him crash through multiple tables

Cecilia: You can flirt with me all you want, barg about your knowledge, or say your the most powerful man, i do not care. But, insult my husband one more time

She send him a hateful glare, as it was a first for Cecilia

Cecilia: And death will look gentle in front of what i will do to you

He fainted of fear, as i grabbed the hand of Cecilia, and walk back home

When we got to our room, i closed the door, as Cecilia was worried

Cecilia: Dear? Is there something wrong? W-Was i too harsh on him?

Y/N: You.....

Cecilia: Y-Y/N?

I look at her, smiling gently, small tears falling from my eyes

Y/N: I can't be more grateful to be your husband, Cecilia

She smiled gently at me, before we sat on the bed

She placed my head on her lap, and caressed it gently

Cecilia: And you don't know how much hapiness you bringed to me since we met...... Thank you, Y/N, for being my husband, and staying with someone like me, while you could have a better woman......

Y/N: Idiot..... I choosed you because i love you forever, and ever.....

We smiled at each others, enjoying the night in peace

Chapter 17: Finished

A/N: On the next chapters, i'm going to work more on the bond between Cecilia and Y/N, because i think, i didn't work on it enough

Anyway, see ya next time!
