(1 years later.)

In The past 1 year humanity have recovered from the attack of the Sirens invasion.

Thanks to the arrival of the great Celestial who saved humanity.

Y/N was revealed to the world and everyone was shock to know another extraterrestrial came to the world.

But this time he help them and humanity have mannage to rebuild there cities back thanks to the help from Y/N he keeps using his last name Ethereal and haven't told his full name.

And the miracle that he gave to humanity was the mental cube a mysterious artifact that the Celestial wield they also learn that the Sirens possess this mental cube also.

They used this to create what they now call as ships girls because they used the wisdom to turned ships into human girls with the armaments of a ship.

Y/N gave this to the whole world and many used is wisely they didn't declare war at each other when the receive this gift from him.

Instead they used this to help each other many were inspired of Y/N for helping them instead of enslaving or destroying humanity.

Many have thought that waging war with each other will only bring the extinction of humanity.

So they have decided to join forces with each other and fight one common enemy and those were the Sirens.

They have made several Faction but there are 4 of the largest faction this are Eagle Union this was the United States but it has change since both South and North have become a one nation forming the Eagle Union.

Then there is Sakura Empire which was formerly Japan but know have unified with Korea,Thailand,Indonesia, and Malaysia.

The next was Ironblood formerly known as Nazi Germany but a revolution occurred overthrowing the Nazi members and their leader and also unified with Poland,Austria,Hungary,Greece and Belgium.

The last is the British Empire or known as the Royal Navy they have unified with India,Australia,and the upper part of Africa.

With Y/N he have turned Africa into fertile land making everyone that live in Africa praise him and many were crying in tears of joy as they won't be suffering from poverty anymore.

This were the 4 largest Faction that created the organization known as Azur Lane there are some smaller factions, like the Northern Parliament which was formerly Soviet Union until there leader died from a heart attack and the new leader have change some rules that won't make the people suffer anymore from the old dictators regime ,Iris Orthodoxy which was formerly France which has now unified with the lower part of Africa and many smaller factions.

And if your wondering how did this ship girls came into existence well let tell this.

The mental cube were the basis of which the ships girls are created.

Imbued with immense power that is capable of fighting against the Sirens and with it they mannage to reclaim the sea.

But this ships girls are still children's since there age is different than that of a human the example is 1 year old age for a human is 7 years to that of a ship girl.

Y/N was staying in a base a 1 kilometer away from new York city where he was training and letting the little ship girls to play around.

The other Factions also trained there ship girls and treat them like human beings and not view them as weapons or tools of war.

And here we are in Neon Base as It was a peaceful day in the base today as nothing wrong was happening.

*Boom*

Ok it wasn't a peaceful day and there was seriously something wrong happening inside the base.

As we could see a small 6 year yellow haired child running away from a 7 year old white haired girl.

????:Hornet give me back the teddy bear that Onii-chan gave me.

Said the white haired girl as she aims her small bow at the yellow haired girl.

Hornet:never big sis enterprise this will be mine.

Hornet said as she hug the small white Teddy Bear while sticking her tongue out infront of her older sister who's name was enterprise.

Which made enterprise mad as she pulled the string on her cute little bow as a Yellow arrow appeared on it before she fire it towards Hornet.

As the arrow then transformed into a 4 cute mini plane that carries small mini bombs.

Hornet seeing run faster than ever as she tries to escape the 4 cute mini planes.

Hornet:Aaaaaaaaaahhh Big Brother help!

Hornet yelled as she was hit by the shockwave from a bomb that exploded near her.

Sending her straight flying to the air as she was about to fall a blur catches her before landing to the ground.

????:are you alright hornet?

Asked a male voice that just save Hornet from falling to the ground.

When Hornet opened her eyes she saw a 25 year old man holding her.

Hornet:Big Brother ,enterprise is hurting me.

Hornet said as she made a cute face that would have made anyone walk to her and help her but not for this man as he already got use to this.

This was none other than Y/N during his stay in the Eagle Union he has ordered his fleet to stay outside of earth to monitor it from above incase the Sirens attack Y/N would be prepared.

Y/N:Enterprise what did I say of not using violence and why did you try to hurt your little sister?

Y/N scolded at Enterprise as we could see the little girl was about to burst into tears.

Enterprise:but she stole my Teddy bear and won't give it back.

Enterprise retorted as Y/N look at Hornet who was sweating.

Y/N:is this true Hornet?

Y/N asked to hornet as the little girl look down in shame.

Y/N:*sigh* why don't you give your big sisters toy back and I will give you a teddy bear to.

This made Hornet lit up as she went to her sister and return the Eddy bear back.

Hornet:ok here big sister sorry for stealing it from you.

Hornet said as Enterprise took the Teddy Bear back.

Enterprise: it's alright your my little sister I wouldn't be mad at you for long.

Enterprise said as both sister hug each other while Y/N just smiled while looking at the two.

Y/N:alright how about we go get some ice cream.

Enterprise/Hornet:Yay😄

As the three left and went inside on of the kitchens Y/N went to the fridge and took some ice cream.

Y/N:well here you go and eat as much as you like.

Enterprise/Hornet:thank you Big Brother.

Y/N:your welcome you two.

As Enterprise and Hornet were enjoying themselves eating another girl came into the kitchen.

????:Onii-chan you here?

Y/N look at the door and saw a 8 year old walking in.

Y/N:I am here Yorktown.

Yorktown:Onii-chan I'm hungry?

Y/N:what would you like to eat?

Yorktown:I want to eat some fish.

Y/N:ok come join here with your sisters I will be cooking your favorite fish for you.

Yorktown:ok.

Yorktown cheered as she went to sit with her sisters.

Enterprise/Hornet:we want some to Big Brother?

Both the two other girls ask in unison as they have already finnish eating there ice cream.

Y/N:alright just wait here for a moment I'll be back in a few minutes.

Y/N:said as he went to cook there favorite fish to eat.

Yorktown:morning Hornet, Enterprise.

Yorktown greeted her little sisters.

Enterprise/Hornet:morning to you to Big Sister.

Enterprise and Hornet said in unison as the two talk with there big sister while waiting for the food to finnish cooking.

Then the sweet aroma of a delicious fish was smelled by the three as they began to drool.

It wasn't long before Y/N came out with a 3 fish in a plate that had some vegetables on the sides.

Y/N:alright you three can eat now.

Y/N said as when he put the food on the 3 they immediately ate it with a face of pure ecstacy.

As Y/N just chuckled at this as he drank some coffee that he just made.

Timeskip

After they finnish eating the three played in a small garden.

Hornet:catch me if you can big sis.

Hornet said as she was riding a small mini plane that is enough to fit her as she flew in the air.

Yorktown: no fare that's cheating.

Yorktown said as she then summon her own plane and flew after Hornet.

As Y/N just sitting on a balcony watching the three played with each other.

Just then a small blur pounce on Y/N but luckily Y/N already expected this as he catch the intruder.

Y/N:gotcha Cleveland.

Y/N said as he holds a 6 year old blonde haired girl.

Cleveland:aww my plan failed.

Cleveland pouted as Y/N just chuckled at this before putting the little girl in his lap.

????:Onii-chan where are you?

Y/N look to where the voice came from and saw another little girl walking around.

Cleveland: I am here Montpelier.

Cleveland wave to the other little girl as she saw as.

Montpelier:Onii-chan there you are.

Y/N:good morning Montpelier how are you doing today?

Montpelier:Good morning big brother I am doing well.

Y/N:well why don't you join us then?

I ask her to come over to me as she sat on my left lap then I felt a tug on my shirt as I look down at and see Cleveland tugging my shirt.

Cleveland:Onii-chan may I ask you something?

Y/N:sure what is it you would like to ask Cleveland?

I said to her.

Cleveland:are we really just weapon of war big brother?

I was shock when she ask me this question.

Y/N:of course not Who told you that lie?

Cleveland:well when we visited the city last week ago I heard the other children telling that I am a tool in human disguise and was only built for war.

Y/N:listen Cleveland no matter what they say don't listen to it your not a weapon of war your a living being just like human but your different because for you and your sisters are very special.

Montpelier:really how special are we Onii-chan?

Montpelier asked this time.

Y/N:because the reason your special is that you have the power to help others that are being harmed and bully by others.

Cleveland:but what if someone try to hurt me?

Y/N:you defend yourself from them but don't go to beat them to much just knock them out.

Cleveland:ok but can you sing me a song Onii-chan?

Y/N:of course my Cleveland.

I said to Cleveland as I put them on a small bed as I made a piano appeared and began to play.

After playing it for a few minutes I look to where Cleveland and Montpelier are as Hornet,Enterprise, and Yorktown where cuddled with each other on the bed.

As I walk to them and kiss there foreheads as I walk out of the room before saying goodnight to them.

Y/N:goodnight to you all my little angels.

I said as I close the door and left.

To Be Continued.
