Y/N P.O.V.

We were searching everywhere for U-chan but no luck. We also got a new member in our search group. Her name is Laffey and she is very sleepy. Anyways, we continued with our search and asked many ship girls ion this. Luckily, someone saw her and we went there for searching her. When we got there, we found U-chan holding by a person. I looked closer at the person and I was suprised to see Ayanami. Now, I am worried that Crimson Axis could do something. She noticed me and her eyes grew bigger because she didn't expected me to see here. Before I could ask her, something caught our attention when something flew with a high speed over our heads. When I turned my head to her, she already disappeared. I am very worried of what Crimson Axis planned. Suddenly, this base was under attack because the sirens started to make sounds. We all ran to the port and activated our riggings. I saw that we were being attacked by sirens. I started to aim with my canons at them and shot. When the shell hit those mass produced siren ships. They were about to celebrate their victory until from the sky , it started rain sakura leaves. I immediately knew that this was Sakura Empire. I put my hand on my chest and clenched it until I realized we are already in a war. I am still considered as an enemy. Then I saw Akagi and Kaga.

Javelin:"That symbol. This is Sakura Empire!"

Akagi:"Greetings, Azur Lane. Nice to see you." *notices Y/N* "Y/N, what are you doing here?"

Cleveland:"Wait, she is from Sakura Empire?!"

Y/N:"Actually, I am from Iron Blood." *turns to Akagi* "Why are you doing this?"

Akagi:"We need to do this because Azur Lane is weak."

Y/N:"Do you really think this is a good idea to use the technology of our enemy?! Your purpose is to fight against the sirens not using their technology!"

Kaga:"Looks that someone was brainwashed. It's a shame to sink you but we don't have any other choice."

I just couldn't believe that I am now a traitor in their eyes. My tears threatened to leave my eyes. Before they could do something, I heard that someone was coming closer. I turned my head from where the person will come. I noticed that everyone was looking to the direction where I was looking. In the distance, I saw a woman with an eagle.

Enterprise:"Enterprise, engage."

Even if it was in the distance, I could hear it. Wait, did she just said Enterprise. Suddenly, I went one step back and they clearly could see that I was a little bit tensed.

Akagi:"Looks like that we need to leave. Farewell, Azur Lane." 

I clenched my hands because Sakura Empire are part of Crimson Axis and are allied with Iron Blood. I was lost in thought until someone put a hand on my shoulder. I looked at the person who it was and it was Enterprise. I could see that she is looking at me with an angry face.

Enterprise:"Why is someone from Sakura Empire doing here?"

Y/N:"I am not from Sakura Empire!"

Laffey:"Wait, Miss Enterprise. She is on our side."

Enterprise:"We will see that."

Timeskip

We were now in the office of my father. He explained everything to Enterprise. She wasn't fond of this but atleast I don't have to worry about her attacking me. We started to discuss how we could defeat Crimson Axis but I wasn't feeling very good during the discussion because I have to face my former comrades as well as my daughter Zeppy. I realized that someone was sitting on my legs and someone leaned her head on my right arm. I saw that Unicorn was sitting on my legs and Laffey started to sleep on my arm. I could tell that they were trying to calm me down. I am really glad that there are still caring ship girls. Suddenly, the door was opened and we all turned our attention to the person. When I saw two person, my blood started to boil so much because a ship girl has captured Zeppy. She wasn't looking very fine and I could tell that she was beaten. It was the same woman who treated me horribly. I carefully put Unicorn from my legs on the couch and got up. I could tell that they saw my anger. I went to the woman and slapped her very hard. She even fell to the ground and was about to get up. I grabbed her by the throat and was looking in her eyes with very much hatred.

Y/N:*speaks in a very dark tone* "If you touch one hair of my daughter again, I'm gonna rip and tear you in many parts that you will be more smaller than any atoms. Did you understand me?"

I just saw the fear in her eyes and she was about to lose her consciousness. I released her and turned my attention to Zeppy. I released her from the ropes and was hugging her to calm her down.

Y/N:"Everything is fine, sweety. Mommy is here and no one will hurt you anymore."

I felt how she started to hug me tight and I picked her up. After that, I took a seat on the couch and turned my attention to them.

Jacob:*has a smug face* "Since when you became a mother?"

Y/N:"I became her mother when her actual mother didn't care about her."

Jacob:*laughs* "Hahaha! Didn't thought my former son will become a mother. I don't know if I should be sad or be proud."

I sighed at this. I let Zeppy sitting on my shoulder and we headed to the canteen.

Zeppy:"Mommy, will everything be alright?"

Y/N:"Don't worry, sweety. Like I said, I will protect you no matter what."

I heard her giggling because I could tell that she can be sure that I will be with her everywhere and anytime. When we got there, we ordered our food. After we got our food, we went to a table and started to eat until a ship girl from the Royal Navy took a seat at our table.

Drake:"So you are the two from Crimson Axis, right?"

Y/N:"Have a problem with that?"

Drake:*chuckles* "Easy there, tiger. I didn't come for making any problems like a certain one from Eagle Union."

Y/N:"Who are you?"

Drake:*smiles* "I am Drake, a heavy cruiser from the Royal Navy. And you?"

Y/N:"I am Y/N. Former known as Y/N L/N but nowadays as a part of the FDG (Friedrich der Große) class."

Drake:"Wow, didn't expect from someone with a high caliber. Wait, did you say Y/N L/N? L/N as our Admiral L/N?"

Y/N:"Correct. He is my father."

Drake:"Didn't know that you are the daughter of our admiral."

Y/N:*mutters* "I was actually a boy."

Drake:"You said something?"

Y/N:"Nothing."

Drake:"Anyways, it was nice to meet you, Y/N. Hope that we can get along with each other."

Y/N:"Likewise."

I saw that she got up and left the canteen. Maybe not everyone from Azur Lane is that bad. Anyways, we finished uo with our food and were straight on our way to our dorm. Luckily, my father gave me the key for our dorm. When we finally entered, I went straight to the bed. I felt how Zeppy was putting her arms around me. I giggled at this because it was very cute from her. I put over our bodies a blanket, kissed her forehead and she started to close her eyes.

Y/N:"Good night, sweetie. Have a nice dream."

After I said this, I started to close my eyes and went myself sleeping.

Timeskip: next morning

I woke up and saw Zeppy's sleeping face. I was smiling and let her sleep. I quickly made myself ready for the day until I heard her yawning. She got up and was looking at me.

Zeppy:*with a sleepy voice* "Morning, mommy."

Y/N:"Morning, sleepyface."

She changed herself into her clothing and we left the dorm to the canteen. During the way, we met Javelin, Unicorn and Laffey. I was glad that they befriended with each other until the sirens started to make sounds. I told Unicorn to bring Zeppy to a safe place. We all headed to the port, equiped our riggings and jumped onto the water. My eyes grew bigger when I saw everyone from Iron Blood along with the Vichya Dominion. Luckily, on our side were the Royal Navy, Eagle Union and Iris Libre. We were facing them until Enterprise stood in front of us.

Enterprise:"What do you want here?"

Bismarck:"We came for two of our members." *notices Y/N* "Y/N, you are here?"

Y/N:"Bismarck, are you really came for us?"

Bismarck:"Of course."

Y/N:"Bismarck, tell me. Are Crimson Axis really using the siren technology?"

Bismarck:"We are using them to destroy our enemies."

Y/N:"THAT'S BULLSHIT!"

I saw that everyone was shocked from my outburst but I didn't care.

Y/N:"If you are using their technology, then I am your enemy! I won't forgive the sirens what they did to me and I swear that I will defeat everyone who will be my enemy!"

I saw that she was shocked with my decision.

Bismarck:"I see. Then I see no other chance to challenge you into a duell. If you win, Iron Blood and Vichya Dominion will leave Crimson Axis and rejoin Azur Lane. And if you lose, you have no other choice to join Crimson Axis. Same goes for Zeppy."

Y/N:"Leave Zeppy out of this. She doesn't have to do this. This is only about me and you."

Bismarck P.O.V.

I saw her determined expression. She tries to protect Zeppy where ever she can. I am pretty sure that you are a perfect mother material. I readied my spear to fight against her.

Bismarck:"Well then, let's start with our duell."

Y/N:"En garde!"

I was suprised at this and didn't expect her know the language of Vichya Dominion or of Iris Libre.

Y/N P.O.V.

After I said this, in my hands there were two pistols.

I started to shoot at Bismarck and it hit her. But it didn't impressed her much. She sailed at me with a high speed. I dodged her attack, ducked and kicked her legs with a turn. She fell on the water and I placed one of my pistols on her head. 

Y/N:"You are defeated."

Bismarck:"You have defeated me fairly."

I removed my pistol and and helped her to get up. Then I saw that she looked at Iron Blood and Vichya Dominion.

Bismarck:"As you saw, I lost the duell and I must hold my word. We are leaving Crimson Axis and rejoining Azur Lane."

I was very happy that my comrades from Iron Blood joined us. Now, we have to face Sakura Empire and Sardegna Empire. 

A small timeskip

After that event, Bismarck, Prinz Eugen and Jean Bart were in the office of my father with Enterprise, Hood, QE (Queen Elizabeth), Warspite, Cleveland and Belfast.

Jacob:"It's great to have to Iron Blood and Vichya Dominion on our side. Anyways, we need to focus on Sakura Empire. If we defeat them, we can finally focus on our main enemy: the sirens."

Sakura Empire will be hard to defeat. After it was decided, I was about to leave until someone pulled me into a kiss. I saw that it was Bismarck kissing me. After she broke the kiss, I was immediately next by Prinz Eugen. Damn it, I guess this is her repayment for what I did to her in the bathroom. She also broke the kiss with me.

Jacob:*chuckles* "Didn't thought that you captured the heart of Bismarck and the Tease Princess of Iron Blood, Prinz Eugen."

I was looking at Bismarck and P.E. I could tell they were waiting for my answer. Suddenly, I all remembered the good times I spent with them and I decided to give them my answer by kissing them back. When I did this, I could tell that they didn't expect this. After I returned the kiss to them, I put my forefinger on my mouth.

Y/N:"Does this give you an answer?"

P.E. :"Then it's official."
