"Muzuki-chan, get up. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo”

"Woo, let me sleep a little longer, I don't have a class today・・・・・・"

"Really, I can't help you."

With a sigh, the girl picked up the comb and slowly combed her silky hair.

This is the world of the ship's mother.

It's been about a month since Ruyue was sent back by us. After the initial joy and excitement, Ruyue's sisters, as well as the ship's mothers, want to learn from Ruyue about the time she disappeared. But there's really nothing to say, it's just that someone saved me. So Ruyue weighed it off, but she still hid the things of the other world, and just said that Akai and I were two fishermen who were going out hunting.

But this can't be blamed on those curious ship girls, after all, there is no one else in the entire town guard mansion except for the ship girl and the old admiral who disappeared all day long.

Everyone looks down every day and doesn't look up, and there are not many gossip questions to talk about, so they are quite interested in what Ruyue encountered.

It took about half an hour, and after finishing grooming, Ruyue walked to the drawer under the bed and squatted down, opened the drawer, and took out an object about more than a meter long from it.

"Whew, I should need to do some maintenance today, uh, the knife oil should be placed here, ah, I found it~"

Slowly unsheathed, this is the katana I gave to Kiritsuki at the time, and the weapons produced in the MC world are of excellent quality.

During this time, Ruyue has worked very hard, not only on the content of the course, but also on what Akai and I have taught.

One of them is the use of chopping and small arms.

Although from the overall direction, the ship mother doesn't seem to have any chance of white-knuckle combat, and basically all of them use the artillery in their hands and the torpedo in the fish **, but Ruyue is still practicing alone.

"Yo Xi, the rearmament is complete, and it's a new day." Ruyue patted her cheek, then looked at Muyue, who was still asleep, and walked out of the room with a smile.

It is worth mentioning that Ruyue's costume has still changed, and it is no longer the simple sailor suit that Akai and I saw before.

En・・・・・・ Although there hasn't been much change in the strength of the ship's equipment overall, it has improved a lot in terms of individual charisma・・・・・・

Just when Ruyue thought that this day was going to continue to be peaceful, suddenly the voice of the secretary captain came from the radio.

"Operational Meeting." The voice of the royal sister who was full of energy sounded, "All the staff are assembled, there is a combat mission." ”

Ruyue, who was still in the corridor, was stunned with a katana, and then smiled helplessly: "Ahh ”

There was nothing to say about the meeting after that.

The direction of the meeting is still the same as the world line of this world, and it is still the battle against the airfield.

But because of the return of Ruyue, it was changed twice, but it changed from the original world line.

"Allah, is this Xiao Ruyue, how is it, how is it, is it okay to sleep at night?"

Dressed in an OL teacher's outfit, he walked down the aisle with a bunch of student homework and Ruyue in his arms.

"Ashigara-sensei, don't make fun of me, it's been hard lately, whether it's normal practice or something." Ruyue replied helplessly.

Ashijo looked at the katana that Rutsuki was holding in her hand, and although it was wrapped in cloth, the handle was still exposed.

"Speaking of which, you've been carrying this since you came back that day."

"Yes! It's something important. Ruyue clenched the katana in her hand and looked at it carefully.

"I must not give up hope, use all the resources at my disposal, and plan ahead and think about any unexpected things that will happen during the battle・・・・・・" Ruyue closed her eyes, like a treasure, "These are the fighting methods that those two adults taught me, so Ruyue must work harder, in order not to make the people who care about sad." ”

Ashigara gently touched Ruyue's hair in admiration, "What a good boy, speaking of those two, they are really excellent men, really, why can't you stay for a while longer, should I take the initiative to attack to find it・・・・・・ oops, it's really nerve-wracking." ”

Looking at the foot handle that was in the usual fragmentation on the side, Ruyue smiled awkwardly. After all, it's not a world, so it's useless to look for it.

In this raid operation, Rutsuki and Fukiyuki set off as frigates with Zhenghang Akagi. Fukiyuki has a good ability to shoot at the air, but Ruyue's words・・・・・・ although I don't know what the Nagato secretary ship thinks, but once it comes, it will be safe, and Ruyue said that as long as she does her best, it is enough.

Touching the three pink feather ornaments in his hair, the crimson gems at their junctions inadvertently shimmered with hidden brilliance.

――――――――――――――――I'm a dividing line――――――――――――――――

The world line is wonderful, and cause and effect are always mutually reinforcing.

Where there is a cause, there is an effect.

Akai and I saved the dying Ruyue and sent it back to the world of the ship's mother, how can there be no change in such a big world line?!

The butterfly effect, which sounds like nonsense, is terrifying when you think about it.

[MI Raiders], the flying field of the Pacific Ocean, although not a powerful enemy, has a large number of deep-sea guards.

In the face of the powerful firepower and aerial suppression of the almost fully dispatched town guard ships, there is still no room to fight back.

But!

"Well, that's impossible!"

“poi！”

"It's not the same as what the intelligence said.,Why is there such a guy here besides the Flying Field Hime・・・・・・"

"Woo whoa, what to do, Thunder, it's terrible・・・・・・"

In the fierce artillery bombardment, although the enemy flight field Ji has a good ability to regenerate himself, but he is still powerless to return to the sky, as it should be.

However, I don't know why, in the last round of fire, other deep-sea flagships appeared to save the flight field Ji.

Subsequently, the ship girls of the town guard mansion were surrounded by a large number of deep seas that appeared in groups at some point.

Battleship class changed to flagship, nicknamed Master (I heard you haven't been broken)

Battleship タ-class flagship,People send the nickname Tower Sister,Door God。

Battleship レ-class elite, Lei Ye (what are you afraid of, at most you will fall into the ditch)

The empty mother level is changed to flagship, and there is a lot of blue phosphorescent wo change in his eyes.

Not only these, but all kinds of ghosts, water ghosts, and deep-sea air mothers, these terrifying existences are almost all there. No matter which one it is, it is an opponent who needs all the ship girls in the town guard to do their best and may not be able to beat it.

There is no way out, there is no so-called protection of the big break, and there is no desperate realm.

"It's ・・・・・・ to lie to people." Akagi stared blankly at the powerful enemies that appeared one after another around him, completely surrounded, and there was not even the slightest possibility of a surprise attack.

Fuyuki on the side raised the anti-aircraft gun in his hand with a resolute expression: "No matter what happens, I will protect Akagi's predecessors." ”

"Blowing Snow ・・・・・・"

The artillery fire rang out again, and all the deep seas attacked except for all the deep sea flagships.

The shipwives burst out in despair with their last belief in survival.

"Danger!"

Knocking down an enemy plane, Fukiyuki finds that a cannonball is heading straight for Akagi, who has no ability to dodge.

"Akagi-senpai, cannonballs !!"

Looking at the hoarse blowing snow with his outstretched hand, Akagi smiled slightly, as if he had accepted his fate.

Then, he slowly closed his eyes.

Bite!!!!!!

"I can't give up, Sister Akagi."

Suddenly opened his eyes, in front of Akagi, a long dark purple hair fluttered in the air, and in Ruyue's hands, a katana collided with the cannonballs that fell in front of him, and a large number of sparks exploded.

"Mmmm!!mm Carrying the huge pressure, Ruyue concentrated the strength of her whole body to a point, recalling the way she had been taught to slash and slash, and pushed out the strength of her whole body.

The shell, split in two, fell into the sea on both sides.

"Okay, that's amazing." Fukiyuki said dumbfounded.

Ruyue straightened the katana again, and the other armor on her body had long been broken, and even if she had, there was no ammunition, and the only weapon in her hand was this sword. Even so, Ruyue was still in front of Akagi.

"It's too early to give up, as long as you have hope in your heart, you will definitely not die." Ruyue turned her head and said to Akagi seriously.

"But ・・・・・・"

"No, but, there will be a way, everyone in the town guard is waiting for us to go back!"

Gently reprimanding Akagi, Ruyue waved the blade in her hand very simply, without the slightest fancy, but blocked the oncoming cannonballs one by one.

Ruyue seemed to think back to the topics that Akai and I had talked to her about.

Questions about cause and effect.

For a period of time, there has always been a question in Ruyue's heart, that is, if cause and effect really exist, then how could she, who had died in the original world line, be able to stand here unharmed now without a price.

By now, the answer is obvious.

It is no coincidence that these powerful deep-sea flagships were supposed to be scattered in various seas, and today, they are gathered here, this is the punishment given by the world.

It can also be said to be a graduate school entrance examination.

It is the price of resurrection of the dead.

Survive this calamity, and everything will be smooth sailing after that.

"I'm sorry, everyone, because of me."

Ruyue thought guiltily in her heart, this is her responsibility, so even if everyone gives up hope, she can't give up.

And the way to break the game・・・・・・ Ruyue seems to have a little understanding in her heart.
