I felt like writing something on this story so I'll be doing a little side story/filler. This will be technically cannon to the story but it won't directly affect it in anything important apart from some references to future things. Have fun reading it :)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Y/n: "*sighs* It's been rather dull lately"

Thankfully, no trouble has arised since the battle with Kama. Heaven, Hell and Earth have all been in a time of peace for once since I took over. The problem was..

Y/n: "There's so much fucking paperwork!!"

I bang my head on the table while grunting. Not even my Caster form could help with my struggles of stress and making sure everything was organized.

Siduri: "Please don't be like that my king. If you slam your head on the desk again, you might risk having all our work fall onto the ground and we'd have to start over"

Y/n: "Sorry"

Amagi: "I've solicited some to help us with this to ease the burden on you Commander"

Y/n: "You both have my thanks"

Amagi: "Of course. It's our job as your secretary and CFO to take care of matters like these"

Siduri: "Taking care of paperwork is right up my alley"

There was a knock at the door.

Y/n: "You can come in"

The door open as Eucliwood, Isla and X walked in.

X: "We bring food and drinks"

Eucliwood hands Amagi some tea and snacks while Isla gives Siduri some coffee and sweets. Meanwhile, X gave me a plate that was half eaten and an empty cup.

Y/n: "You ate all my shit!!"

X: "No I didn't"

Y/n: "What's all those crumbs on your face?"

X quietly removes them off her face while starring at me expressionless.

X: "I don't know what you are talking about"

Y/n: "You removed the eviden-!! Ah whatever"

I open a gate and pull out a holy grail full of wine.

Y/n: "We got pretty far, how about a break for now?"

Amagi: "I guess we could use it. Not much further until we've caught up"

Y/n: "Good. Siduri, how are the costs of the walls and dingirs going along?"

Siduri: "The materials have been paid off and construction for them will commence in a few days"

Y/n: "That's great to hear"

I get up from my chair and stretch for a bit.

Y/n: "You girls go ahead and have the day off. Well continue tomorrow"

Amagi: "As you wish Commander"

Siduri: "I'll take a few of these documents home and check on the details to make sure they match"

Y/n: "Fine, but don't overwork yourself"

Siduri: "Yes sir"

I go to the window and see Mordred training some new men that signed up to join our little military force. It wasn't anything big but it was certainly powerful. Getting trained by a knight like Mordred was a blessing but the regiment was harsh. Out of the 100 that would come in, about 8 made it in under her supervision. That being said, those 8 were strong warriors.

Y/n: "Kuoh will be safe with those men under their eyes"

I walk out of my work room and head off towards my throne. Eucliwood had walked beside me while writing a message.

Eu: "Akagi and Kaga said that the vessels you ordered have arrived"

Y/n: "Good. Can I see the pictures of them?"

She hands me the images of the first two to arrive.

Y/n: "The KOK Kaga"

Y/n: "And the KOK Akagi"

Eu: "KOK?"

Y/n: "Kingdom Of Kuoh. Like the names?"

She nodded as I handed them back to her.

Y/n: "Seems everything has been calm lately. I like it that way"

Eu: "Sirzechs is waiting in the throne room"

Y/n: "He is? Who's with him?"

Eu: "Just him"

Y/n: "Well, looks like we can't keep him waiting"

We make our way through the doors and see the king of the underworld in front of us.

Sirzechs: "Y/n"

Y/n: "Sirzechs"

I shake his hand and guide him to my bar.

Y/n: "What are you doing here?"

Sirzechs: "There's a bit of a problem that's been troubling-"

Y/n: "Of course there is. Just as I was barely getting used to a little quiet around. Tell me, what is it this time?"

I grab two glass cups and grab the whiskey on the top. I pour it on the two cups and drink it.

Sirzechs: "It's not that type of problem"

Y/n: "Well, what is it?"

Sirzechs: "We have a party happening soon and most of the powerful being would like the King of Kuoh to show up. The problem is, there are others who don't want you to show up"

Y/n: "I wasn't really planning on going to begin with"

Sirzechs: "You were aware of it?"

Y/n: "Of course. My "wife" told me all about it. I rejected her and told her I don't want to hear about it"

Sirzechs: "Are you sure? Having Mr. Leviathan show up would help ease the tension of those who reject your introduction to the 72 pillars. Why don't you come along. I heard in particular that Odin would love to meet you"

Y/n: "Ha? Why does that old man want with me?"

Sirzechs: "Something about him supporting you and the movement you are doing. He would love to meet the king of the humans as he said"

Y/n: ".. Buttering up to me with compliment. *chuckles* The cheek of that old man. *sighs* Fine, I guess I'll show up"

Sirzechs: "He says he has a gift as an offering of sincerity"

Y/n: "A gift?"

Sirzechs: "Something about a Valkyrie and a powerful weapon"

Y/n: "Hmm.. I guess I shouldn't just turn down such an offer. Have my wife give me the details of when this little party of yours is gonna happen"

Sirzechs: "Of course. Would you like to travel with us?"

Y/n: "If you're offering"

Sirzechs: "It'll be my honor to have Humanity's Observer and Slayer of Beasts, the King of Kuoh and Successor to the great King Gilgamesh on my train"

I smile and laugh to myself as Sirzechs drinks from his cup.

Y/n: "You two do have a way of flattering others"

Sirzechs: "As you requested, I've passed the legend of Gilgamesh to our historians. As of today, The Legend of Gilgamesh, King of Uruk, has officially been inscribed into our minds and hearts as well as books"

Y/n: "Thank you Sirzechs. I'm grateful for your help"

Sirzechs: "It's the least I could do for his sacrifice. I'm sure he's somewhere looking onto you proudly"

Y/n: "Yea.."

I put the cup down and sit down on the stool.

Y/n: "What now?"

Sirzechs: "I'll be heading back to the Underworld and send the news of your arrival to the others. I heard you have a lot of work going on right now"

Y/n: "It is, but luckily I have Amagi and Siduri to help me out with it"

Sirzechs: "As an oath of our friendship and alliance, please feel free to ask me for help. I wouldn't mind sending some of the smartest minds in the underworld to aid you with the work. I'm sure Grayfia and Sona wouldn't mind either'

Y/n: "I appreciate it. I'll let you know if I require it"

Sirzechs: "Well then, I must be going off now. The drink was the best I've had in a while"

Y/n: "I only carry the finest. Let me know if you'll be stopping by again next time"

Sirzechs: "Of course. I'll be taking my leave now"

He exits the room as I go towards my throne. I sit down and take a deep breathe while closing my eyes.

Y/n: "Use my Clairvoyance"

I open them and see that nobody has made any drastic moves towards Earth. Kiara, who was the closest, had slowed down her movement while Goetia stood still. Tihexa was still locked up and Astarte was sticking around the stratosphere but hadn't made a move that could of harmed Kuoh.

Y/n: "What the hell are you up to?"

All she did was float around and looked at the world below her. I shut down my Clairvoyance and reached into Babylon for a drink.

Y/n: "I have to continue to monitor them.. Why does this drink taste weirdly?"

I heard a poof and white smoke surrounded me.

Y/n: "What the-?!"

Mordred: "Master, I've come to report-"

The smoke died down and she dropped her notes.

Y/n: "What the hell?!.. It appears I've de-aged from the looks of things? What a stupid thing for me to do"

I look to see Mordred's eye twitching.

Y/n: "Mordred. Good of you to come. Looks like I'll be needing some aid in fixing this. Can you take me to Ahri- OOF!!"

Mordred: "My god you are cute!!!"

Y/n: "Mordred. Unhand me woman. UNHAND ME I SAY!!!"

She buried me into her chest and was shaking me from side to side.

Y/n: "Urgh.. I think I'm actually liking this now"

After Mordred got a fill of her love out, she set me down with a big grin in her face.

Mordred: "Sorry about that master. I guess I got a little excited from seeing you so.. young"

Y/n: "It's alright. Now, back to what I was saying. I need to go see Ahri to figure out how to revert myself back"

Mordred: "Do.. do you have to?"

Y/n: "YES!!! How the hell else am I supposed to rule Kuoh as a child?"

Mordred: "By slapping everyone with money"

Y/n: "That's not how it wor-.. Actually, that's exactly how I did things. That's not the point!!"

Mordred: "Fine, but on one condition"

Y/n: "Condition? I am your master!!!"

Mordred: "I won't help you then"

She crossed her arms and turned.

Y/n: "Argh. Fine!! What's this condition?"

Mordred: "Well, it's two actually"

Y/n: "Just spill it already"

She turned around and smugly looked at.

Mordred: "You have to call me Big sister Mordred"

Y/n: "Haaa?!"

Mordred: "You also have to hold my hand anytime we go into public and or just walk anywhere"

Y/n: "What kind of-"

Mordred: "These are my proposals. If you can't agree to them, I won't help you"

My head drops as I have to surrender to being nothing but a child.

Y/n: ".. Big.. Big sis Mordred.. Can you please help me?"

I can see blood running down her nose as she gives me a thumbs up.

Y/n: "Too easy"

She sticks her hand out to me as I look at it curiously.

Y/n: "What?"

Mordred: "You have to hold my hand remember?"

Y/n: "Oh.. Right"

I grab onto it as we begin to walk out. There were countless eyes on me the entire time.

Woman: "Oh my God, is this our King's child?!"

Man: "But who's?"

Woman: "It's obviously Miss Mordred's. Wow, look how much he looks like him"

Woman 2: "What are you talking about, she is obviously only his bodyguard. Have you seen how close our King and Miss Eucliwood are? It's clearly their child!!"

Woman: "Are you saying a King and his bodyguard can't have anything in secret?"

Man: "He looks like X to me"

I sink into the ground as I overhear everyone's gossip.

Y/n: "Just kill me already"

Mordred seemed unfazed as she happily walked through the halls.

I managed to survive a horde of women and men wanting to see me better as we walking into Ahri's alchemy lab.

Mordred: "Ahri, we got a problem"

Ahri dropped down from the second library with grace as she looks at the two of us.

Ahri: "SO CUTE!!!"

She quickly takes me onto her arms as she rubs her face onto mine.

Y/n: "RELEASE ME YOU FIEND!!!"

Mordred: "Hey!!"

Ahri: "Wait.. I didn't know you and master had a child, muchless in such short amount of time. Guess peace really does mean sexy time"

Mordred: "HE IS NOT MY CHILD!!! That is master himself"

Ahri: "Huh?"

She looks at me as I pull the potion I drank on accident earlier.

Y/n: "I drank this. Help me find a cure"

Ahri: "It really is him"

Mordred: "A child between us?.."

She grabs onto her stomach and turns a little red.

Ahri: "Let's see master.. a youth potion. It'll be a little tough but I think I can manage something"

Y/n: "How long will it take?"

Ahri: "About 30 minutes"

Y/n: "Fuck"

Ahri: "You don't have any reverse potions inside of Babylon?"

Y/n: "I don't know. Babylon is infinte"

Mordred came around Ahri and pried me off her hands.

Mordred: "Well, while you work, I'll protect master"

Y/n: "What the is happening?!"

Ahri: "Meanie. Fine, I'll get working"

Y/n: "Thank you"

Mordred: "Take your time"

Y/n: "DO NOT!!!"

Ahri leaves to start working while I reach into Babylon. I searched for about an hour through a few options until I stumbled upon something that could help.

Y/n: "Reverse potion?"

Mordred: "Do you really have to change? Why don't you stay that way for a bit? I could pamper you in the meantime"

Y/n: "While that sounds incredible, I'd like to become my usual self. You can pamper me after as your punishment"

Mordred: "Punishment?!"

Y/n: "Yes"

I pop the top open and drink it.

Y/n: "I hope that does it"

Nothing happend.

Y/n: "Are you shitting me?"

Mordred: "Yay!!"

She jumped over me and pinned me to the ground.

Mordred: "I guess for now, I can give you a little punishment for all the times you played with me~"

Y/n: "Oh hell no!!"

She put her leg in between mine as I felt my heart beat faster.

Mordred: "Now now master, no need to struggle~"

*POOF*

The smoke got her off me as I felt my body change once again.

Y/n: "FUHUHAHAHAA!!! You've toyed long enough Mordred. Get ready for payback.. huh?"

Y/n: "What the hell is this?"

Mordred tackled me to the ground once more as she grinned at me.

Mordred: "Well would you look at that-"

Ahri: "What's going on?"

We look up to see Ahri with an elixir in her hand.

Ahri puts the elixir on the table and walks over to us.

Ahri: "I guess we can enjoy our time for now. The elixir is done but there's no need to rush~"

Y/n: "Fuck.."
