Y/N P.O.V.

I groaned in pain and opened my eyes. When I was looking around, I saw that I was in a medical room.  I tried to get up but I couldn't. In the next moment, someone opened the door. I saw that there were a woman with red clothing with a stern expression, a little girl with a crown, a woman with blue clothing and to my suprise, my mother.

Q.E. (Queen Elizabeth):"Looks like that you are finally awake. Now, tell us who you are."

Warspite:"Your highness, can I talk with him?"

Q.E. :"He is all yours."

I saw how my mother nodded at this small brat girl. She was looking at me with a serious expression.

Warspite:"Who are you and did you call me mom?"

I sighed at this and closed my eyes because there will a be lot explaination.

Y/N:"This is a long story."

Warspite:"We have time for that."

Y/N:*sighs again* "I came from another world where we were defeated by you."

Wales:"So you are saying that you are a siren? It's the first time that we will see a male siren with a rigging."

Y/N:"I got this rigging from my mother and the sword was from my mother. They sacrificed their lifes in order to sent me into this world."

Hood:"Hold on. You are saying that this sword which you had in your arms belonged once to your mother, am I right?"

Y/N:"Correct. Anyways, is there still a war between Azur Lane and Crimson Axis?"

Warspite:"No, why do you ask?"

Y/N:"Does it mean that they rejoined Azur Lane?"

Wales:"Yes, they did. But now answer our question. Who are you?"

Y/N:"I am Y/N. A siren from another world with the rigging from my father who was once a member of Iron Blood and a sword from my mother was part of the Royal Navy."

Warspite:"Wait, you mean that this sword was given to you. Could it be possible that the Warspite from your world was your mother?"

Y/N:*looks away from her* "That's right."

Hood:"Who is your father? You mentioned that he was part of Iron Blood."

Y/N:"He was the 3rd ship of the Bismarck class."

Q.E. :"This doesn't explain why you have his riggings."

Y/N:"I got his riggings when Azur Lane attacked us again and also defeated us. My parents sacrificed their lifes for me so I could survive. I won't tell anything more to you."

Q.E. :"This is all we needed for."

I saw that they left the room and I sighed in defeat. 

Timeskip: some days later

After I fully recovered, I could only go with the supervision of a ship girl. It was decided that I will accompanied by Warspite because that little stupid brat said it. I didn't have a choice about this so I just accepted it. She was showing me the base and I could tell that I felt everyone was glaring at me ready to kill me. After a while, I hit something on my foot and I turned my head downwards. I saw a white plush unicorn. Strange, a unicorn. Wait a moment. I chuckled at this because I already know this belong to which person. I went on my knees and grabbed it carefully.

Y/N:"Hey, buddy. Lost your owner? Don't worry, I will help you to find her."

I saw that it was thinking if I was lying to it and I showed that I truly mean it. It relaxed and jumped on my head. It made itself comfy there and was sitting on the top of my head.

Warspite:"Didn't know that you could calm it down."

Y/N:"In my world, there was also a Unicorn. She treated me like her big brother. She was the most cute and adorable little sister I had."

Warspite:"Why was? What happened to her?"

Y/N:"She got killed after the new Azur Lane forces declared war on us. I'm still blaiming myself for not to be next to her when she died."

Warspite:"She was a precious person to you, am I right?"

Y/N:"Indeed." *sighs* "I don't wanna talk about such sad things right now."

I saw that she nodded and we started to search for Unicorn until we found her at place with a fountain. I also noticed there were Javelin, Z23, Laffey and Ayanami. I grabbed it U-chan and went to Unicorn.

Y/N:"You are looking for him?"

I saw that they turned their heads to me with a suprised expression. I gave U-chan to Unicorn and I could tell that she is very happy.

Unicorn:*speaks with a shy voice* "Thank you very much, Mr."

Suddenly, I remembered the time when Unicorn from my world thanked me.

Javelin:"Something happened? Why are your eyes leaking out?"

I realized that I shed some tears. I quickly removed it and chuckled nervously.

Y/N:"Nothing serious. Anyways, have a nice day."

I was about to go until Z23 called me.

Z23:"Wait. You are the siren boy!"

Y/N:*sighs, then turns his head to them* "Even though, I am a siren. It doesn't mean that I am like the other ones you met before my arrival."

With that, I went to my mother and we continued with our walk. I noticed that it was getting late and I asked where I could sleep. My mother said that I will be getting a room for myself soon. For the meaning time, I have to sleep with Bismarck.

Y/N:"Wait, did you really said Bismarck?"

Warspite:"Yes, I did. Is there something wrong about this?"

Y/N:"I am a little bit worried that she could blast me to oblivion."

Warspite:"Don't worry, she won't. They will only attack if you show any hostile movements."

I sighed at this and I was escorted to the dorm of my aunt. When we stood in front of the door, I was very nervous about this. I knocked on my door and we were greeted by my aunt herself. I could tell that she was looking at me like her looking could penetrate me.

Bismarck:"I see. So you are the famous siren boy in our base. Come in."

I nodded and waved my mother goodbye. When I entered the dorm, I was suprised to see how big her dorm is. I couldn't help but to remember about the time when aunt Bismarck came to my parents. I was smiling about this and I took a seat on the couch. I saw how she came from the kitchen with a teapot and two cups. She poured into the cups tea and gave me one. I took a little sip and was glad that her tea has the remaining taste like in the past.

Bismarck:"It looks like you enjoy my tea."

Y/N:"I must say that you really can do make good tea."

Bismarck:"Thanks. Now, I wanna ask you some questions if you don't mind."

Y/N:"I don't mind."

Bismarck:"Who are you really?"

Y/N:"I am Y/N. A siren from a former ship girl and a former ship boy."

Bismarck:"What do you mean by that?"

Y/N:"They were my parents. My mother was part of the Royal Navy and my father was part of Iron Blood."

Bismarck:"Iron Blood?! Wait, you mentioned a ship boy? Who is this ship boy?"

Y/N:"I don't if you know him but he was under two names famous. His name from Iron Blood was Kriegsheld (War Hero) and in Azur Lane, it was F/N."

I saw how her eyes grew bigger. So that means that my father exists in this world.

Bismarck:"How do you know the name Kriegsheld?"

Y/N:"My father told me about his past. Another thing is that my father had two older sisters. I mean you and aunt Tirpitz."

I heard how she gasped about this. Maybe it was to much to for her to process it. 

Bismarck:"I see. I think you should meet your father."

Y/N:"Even they don't consider me as their son, I will still love them and protect them even if I have to die."

Bismarck:"You mean it because you are from another world?"

Y/N:"That's correct."

Bismarck:"What happened to them?"

Y/N:"They were killed by the new Azur Lane forces. To be more specific, it was Enterprise who killed my parents. Before you say something, I only hate the Azur Lane who killed my family from my old home. This Azur Lane from this world is not to blamed for what they did."

Bismarck:"I see. Anyways, I will go sleep. You will sleep on the couch. I prepared everything for you."

Y/N:"Thank you."

We quickly cleaned up the teapot and the two cups. After that, I put the blanket and the pillow on the couch so I can sleep there. Bismarck quickly turned off the light. With that, I was laying on the couch and was about to sleep. The last thing I heard was how my aunt went to her bed.
