Sorry about the first chapter confusions, so the Aftermath-Class Heavy Cruiser and the Hades-Class Supercarrier are of my own invention (OC). Although, pointed out by K1LL3R1393, the Infinity-Class is a warship that was due to the fact that it was UNSC (United Nations Space Command) standard. For the UNN (United Nations Navy), it's a huge ship with massive guns so I shall classify the ship as a Dreadnought. Onto other things, I will also introduce the return of the so-called outdated Fleet Boys (OC) that has been remodelled by the UN. So here's the second Chapter of Kantai Collection: The Lost Files.

SHIGAN NAVAL BASE
0900 HOURS
PARADE SQUARE

2 days after the arrival of the 3 UNN ship-girls, a welcome ceremony is held as promised by the secretary ship, Nagato. The ceremony also served as an event that she can use as a commendation to all the Fleet Girls who has fought in Operation MI or The Battle of Midway Atoll as it was officially released.

"Good morning to all of you! I'd like to express my and the Admiral's gratitude and congratulations on the amazing job well done 2 days ago. While I still await the report from the flagships, the Admiral has decided to allow a day off from the paperwork to enjoy the festivities that we have prepared today." Nagato says cheerily. The gathered Fleet girls cheered as they listened to Nagato's speech. Nagato then held her hand up, effectively silencing everyone on the square.

"Today is also a special day as we welcome our friends from the United Nations Navy. Due to our performance in the last battle, the UNN has decided to give us 3 ships. Not just any ships too, the 3 most prized ships in the UNN. I welcome, the UNN ships!" Nagato speaks quickly as she looks into some of the girls' eyes. She steps to the side to allow the 3 UNN ship girls to march up to the stage. Standing in attention, the 3 ship girls saluted as they introduced themselves.

"Heavy Cruiser Aftermath, codename Kerry, Ma'am!"

"Supercarrier Hades, codename Janet, Ma'am!"

"Dreadnought Infinity, Ma'am!"

The assembled fleet girls looked at their newer arrivals with shock. Not knowing what to say, Fubuki shouted, "Attention!" The girls, upon hearing her, all faced forward in attention. On her cue, the assembled saluted. This prompted the UNN girls to lower their arms into parade rest. The Japanese Fleet girls followed suit.

Nagato looks at Fubuki in surprise as she somehow managed to command the entire Fleet into a salute. Forming a small smile on her lips, Nagato tells them to be at ease, allowing everyone to relax. Walking in front of the UNN girls, she faces the crowd and shouts, "Let the festivities begin!" Turning around, she looks at the UNN girls, somehow still in parade rest. "Look girls, you are free to go. Drop the formalities will you? We are of free spirit. We here at the Shigan Naval Base are non-militarilistic. I don't know how you were brought up to be at the UNN Base but please, drop it. It would not do well to the younger ships to see you to be so serious. I hope you have been mingling with your Fleetmates?" Nagato asks.

"I have been as social as protocol permits, ma'am. It has good reason." Kerry says with discipline. She then walks away.

"Oh my god, the other carriers have been so nice to me! I can't resist it, sorry Ma'am. They were showing me around but when they asked the more personal questions, I answered as per protocol." Janet says as she blushes a little. She nods to Infinity and salutes Nagato before rushing of to find Kerry.

"Hmm, I don't quite see what protocol you are talking about. Mind telling me about it?" Nagato asks Infinity.

"It's the Hood Protocol, ma'am. As per the UNS… UNN Rules, as per Operation Midway, all UNN ships are not permitted to create a visible bond between other ships. This way, should a ship be sunk, the other ships would not be affected in combat in anyway that may disrupt the battle plans." Infinity explains without emotions.

Nagato looks miffed. As she listened to the UNN ship's explaination, her expression changed from understanding to sadness to disgust. "So you're telling me that the battle plans are more important that the Fleet girl's feelings?!"

"Essentionally, yes. This way, we would lose far less ships as well as keep our victories enjoyable. Thinking about our lost comrades are very degrading. Some would breakdown should they every think about it. I, personally can see the use of this." Infinity says as tears began to form.

"Hey. Hey don't cry. There's no need for that now. I have yet to see the battle reports but I can see it in your eyes that you care more than you let on. I may not agree with the protocol and I cannot order you to disengage from the protocol. I can, however, tell you that the UNN rule do not apply here at the Shigan Base so it is up to you to decide. Honestly though? I'm pretty sure you've gone far past that stage from what I can see from Fubuki. Seems like you managed to talk the shyness out of that girl. I thank you much for that." Nagato whispers as she held the girl in her arms. Despite being only slightly taller than the girl, Nagato could feel the girl curl herslf into a ball. "Alright. Enough of this. I can see Fubuki, Mutsuki and Yuudachi looking around for you out there. Seems like you really made friends, eh? Clean yourself up, no use in making them see you in this state."

Infinity sniffled as she looks gratefully at Nagato. Wiping her tears, she got up, saluted the secretary once more before running over to her fleetmates. Nagato shook her head as she smiled sadly. Her eyes trailing the girls.

20 Minutes Later

XXXXXXXXXXXXXXXXXXXXLineBreakXXXXXXXXXXXXXXXXXXXXXXXX

Nagato walks up the staircase to the Operation Room to get an update from Ooyodo when she heard the blaring noise of the air raid siren. She dashed into the operation room to see Ooyodo shivering while staring at the radar. Nagato shakes Ooyodo while looking at the radar. "Ooyodo, listen to me! What is it?! I can see things but what it is I don't know!"

Ooyodo shakes her hear when she sees Nagato. Glancing at the radar, she speaks shakily, "Mu-multiple airborne contacts! E-Enemy bombers!"

Quickly, Nagato gets on the intercom. "Man the Anti-Air defences! Carriers, launch the Fighters! All Ships, Sortie!" Closing the channel, she runs out to the hanger to see the 3 UNN girls running up to her. She also notices that all 3 of them appear to be wielding a large pistol.

"Ma'am! What's happening?"

"Air raid. Possible base attack. Where did you get those?" Nagato says quickly, pointing at their guns.

"Quick sortie, ma'am. One of our abilities. We still need full sortie to get get in the water though. If you want, we can defend the facility while your girls sortie. Janet here can launch her TOSSER-class Fighters to support us." Infinity replies just as promptly.

"Very well, but you are to sortie immediately after the last Cruiser. Get to it!" Nagato shouts as she pulls away to the Docks.

Battle Coming in next chapter. Finally get to see the armnements of the UNN Ships eh?
