A/N: So, HoS came home

I got her S-2 Star

I'm a happy man

Y/N POV

It was monday, as everyone was getting ready for their duty, while i was doing nothing, since i'm partially jobless

Y/N: So, i'm just going to stay here, while you girls are going to school. I'm jealous that you can do something

Sirin: Trust me, lesson with Himeko is nothing to be jealous of

Himeko: Oh? Did i hear right?

Sirin: And she is deaf too

Himeko: You're going detention

Sirin: We're out of the school, you can't

Himeko: My duty started one hour ago, yours as a student too, i can

Y/N: Don't be a smartass in the morning

Sirin: And you're not defending me?

Y/N: Look at your mother, and then you understand

She look at Cecilia, and see her smiling sweatly, but her aura was completly different

Y/N: Honey, calm down, you're scaring her

Cecilia: You will talk when i will talk to you

Y/N: No

Cecilia: Sirin, you're grounded

Y/N: You're un-grounded

Cecilia: You want to play like that?

Y/N: You want to eat Brocoli?

Cecilia: I like brocoli now, this won't work against me

Y/N: I see, well then, i guess that special shopping day i prepared for just the two of us can be cancelled

Cecilia: You wouldn't dare

Y/N: I would

Kiana: I don't know why, but i feel like we shouldn't stay here.....

Sirin: I think it's their first arguement

Himeko: Trust me, an arguement between parents is everything but fun to watch, let's just go to class

They walked away, leaving Cecilia and me alone in the room, arguing

Cecilia: Don't make me start with the bad influence you give to our daughter

Y/N: Bad influence? They got smarter since i'm here!

Cecilia: And more rude!

Y/N: .......

Cecilia: .......

Y/N: They're gone?

Cecilia: I think so.....

She rush to my side, hug me, and smile happily

Cecilia: I can stay with you all day, instead of going to class~

Y/N: Yeah, but anyway, what class teacher are you?

Cecilia: Science class

Y/N: Oh

The door opened slowly, as Kiana and Sirin look inside, and see us hugging each other

They smiled, before closing the door, as i realized i had a meeting with Otto

Y/N: I have a meeting with Otto.....

Cecilia sigh, befor getting up too

Cecilia: I knew we couldn't stay together for a day after all....

Y/N: When you say it like that, it's like you want to break up with me

Cecilia: I would never! I love you so much i can't imagine my life without you!

Y/N: The same goes for me, my beautiful Valkyrie

Cecilia: Oh stop that~

We kissed, before chuckling, and preparing for the day

Timeskip

Y/N: You want me to what?

I was now in Theresa's office, Otto was here too, as he asked me something kinda crazy for me

Otto: I want you to assist Cecilia in her Science class

Y/N: Why me? You know i'm not the type to teach thing to people

Otto: You will learn to. You start today, Theresa will take you to the class

Theresa: Why do i have to take him......

Y/N: Let's go midget

Theresa: Kill me......

Y/N: Later

She told me to follow her, as i did, and we were walking in a akward silence

Y/N: ......

Theresa: .....

Y/N: Say, why did Cecilia started to become a teacher?

Theresa: Bbelieve it or not, she always wanted to be a teacher. She choosed Science because you were a Scientist, and wanted to 'continue' your legacy

Y/N: Woah.....

Theresa: What is it?

Y/N: I...... don't know what to say.....

Theresa: For once. We're here

She knocked on the door, before opening it, and walk inside

Cecilia: Principal Theresa? Y/N? What are you two doing here?

Theresa: From today, he is your assistant, he will do what you ask him to without problem

Y/N: Hi

Cecilia: Oh! That is a good surprise!

Theresa: I have work to do, study well

She walked out of the room, closed the door, as i was in front of a class, who looked at me curious, and Cecilia was beaming with hapiness

Y/N: So, Miss Schariac, how could i help you in this lesson?

Cecilia: Oh, we were about to talk about the poison that is the Honkai energy. Since i was touched by it years ago, i think i should share the information with the class. And since you were there too

Y/N: Oh, well then, you can tell then. I will add info if i have to

Cecilia: It would be great!

Student: Excuse me Miss Schariac, but who is he?

Cecilia: Oh! I was so happy i forgot to make the presentation

She smiled, before turning to them

Cecilia: Class, this man is Y/N Kaslana, the maker of the most powerful weapons of Schicksal, the Head Scientist of the group and now, my assistant!

Student 2: But if he is the head scientist, why is he your assistant?

Y/N: Don't ask, you don't want to know

Student 2: O-Oh, okay

Cecilia: Anyway! I will tell you the story of how i got infected by Honkai energy, and how i healed from it, thanks to someone

Y/N: Yeah..... 'someone'

Cecilia: It started 18 years ago, when i was still a young Valkyrie. After gone wrong, i got infected by overusing Honkai energy, and so, the Overseer tasked me to encounter someone that will heal me from it

Student: Who is that someone?

Cecilia: That's a secret. Anyway, i was nervous about the encounter with this person, and so were the other Valkyries. We were waiting for him in his office, but he wasn't here. We thought that he won't come, because all he said was false, and he couldn't save us. That was until the door slammed open, and we saw him walking like nothing happened, and told us he was sorry for being late

Y/N: No, i said 'i made it in time, got it?'

Cecilia: It's the same thing

Y/N: No it's not

Student: Wait, so the 'someone' was Mister Kaslana since the beggining?

Y/N: Yeah

Cecilia: Exactly

Student: No wonder why he is the head scientist of Schisal now.....

Cecilia: As i was saying, he walked inside the room, and at first, most of the Valkyries were doubting his skill. That was until, he could tell who was truly affected by Honkai energy

Y/N: People think that Honkai energy infection come from the over use of weapon, but the most dangerous thing is the Stigmata. The most dangerous ones are the original ones, since they have pure Honkai Energy in them, and so, only a few people can handle the pressure

Student: Do you think we could handle the pressure of an original stigmata

Cecilia: With enough work, yo-

Y/N: No, you will die the next second you activate it

Cecilia: Y/N!

Y/N: It's for the better. If you give them false hope, they will try and die in the end. It's better to lose a dream, but stay alive

Student: You are doing it to protect us, thank you, Mister Kaslana

Y/N: Say it to miss Schariac, she was the one who soften me. If you asked me that question 18 years ago, i would have told you 'you can do it!' just for a laugh

Cecilia: He is lying, he would have told you the truth instantly

Y/N: Yeah, hahaha..... maybe......

Cecilia: What was that?

Y/N: I said 'yeah, she is right, i would have told you the truth'

Cecilia: That's what i thought

The class laughed at our interaction, before we continued the class, in peace

Timeskip

Me and Cecilia were outside, since it was our lunch break

Y/N: Lunch break

Cecilia: Did you make something?

Y/N: Yeah

I took out a box out of nowhere, and open it, revealing a bento i made during the night

Cecilia: It looks delicious!

Y/N: Then eat it, i'm not hungry

Cecilia: Don't be like that, we can eat it together

Y/N: You're well being pass before mine, so eat

I closed my eyes and sigh, resting a little since i didn't had much sleep today

Cecilia: Y/N~

Y/N: Yeah?

I opened my eyes and turn to her, as she made me eat a piece of meat

Cecilia: Good! That's a good boy!

Y/N: Stop trying to pamper me

Cecilia: I pamper you whenever i want~ You are my husband after all~

She kissed my cheek, as i blushed a little, and rest my head on her shoulder

Y/N: Sometimes, i wond-

Before i could finish my sentence, a sort of thread grabbed my leg, as someone pull me toward them

I falled on the ground, as i saw someone in the air, about to stab me, before i kick him away, and assumed my battle stance

Cecilia: Y/N!  Are you okay?!

Y/N: Yeah! 

???: It appears, the game is over, before it even begins

Y/N: Who are you, and what do you want?

???: Well, it's easy. Someone put a bounty on your head, worth of 50 millions, and so, people proposed to kill you. There is 3 of us, but you won't have to worry, i will kill you first

Y/N: I like to see you try

He took a metal staff, before assuming his stance too

I send a punch at him, as he blocked it, and try to hit my side with his staff

I blocked it, before bash him away, and send a kick at him

He blocked it, before hitting my leg, making me lose balance

But i used my hands to have a support, and kick his leg too, and kick him away

He send a flashball at me, blinding me, before i hear a yell

???: I've got you!

The impact never come, as someone placed their hand on my shoulders

Cecilia: I will assist you on this fight, Y/N

Y/N: Thank you honey

???: Enough of this chit-chat, i'm taking you both down

He jumped at me, sending his staff at me, as i blocked it, and heabutted him

I then punch his face, before Cecilia jumped above me, and kick his head, before kneeing his chin

I then punch his face two time, before punching his gut

Cecilia kicked him away, as he came to a stop

???: I won't lose like that!

Before he could realize, me and Cecilia kicked his gut, sending him crashing to a wall

He was now unconscious, as i let out a sigh

Y/N: It's been so long since we didn't fight together, it felt so good!

Cecilia: Who was he? And most importantly, who put a bounty on your head?

Y/N: Meh, should be someone jealous of me, maybe

I grabbed the man, before walking toward Theresa's office with Cecilia, so we could talk about this matter

Chapter 18: Finished

A/N: I said i will make 'bond' chapters between Cecilia and Y/N, but i never said i will stop the plot for it (◕ᴗ◕✿)
