The Fight Against The Sirens And Grimms (Red Alert x Azur lane x RWBY) [AU]

Chapter 1 The Defense of Vale (Part 1)

An Allied fleet is now sailing to Kingdom of Vale for a diplomatic mission. The fleet consist of, 4 Aircraft Carriers, 2 Aegis Cruisers, 5 Poseidon Cruisers, 8 Assault destroyers and 5 Hyrofoils.

Allied Carrier Andromeda

In Y/N and B/N's quarters of the Aircraft carrier, we can see they just woken up and wearing their commander uniform.

Y/N: Yo bro, are you excited for our diplomatic mission on one of the kingdoms of Remnant?

B/N: Yeah I'm surprised that the brass assigned us to be escorting our diplomat to Vale.

Y/N: Not only that, we're also aboard the carrier that defended pearl harbor from the Imperial attack.

Carrier Andromeda and her fleet are known for successfully defending the pearl harbor against the imperial fleet under the command of Captain Rogers and Commander Warren Fuller despite being outgunned and outnumbered.

Then they hear someone knocking on the door.

Y/N: Come in.

The door opens to reveal a man in his early 30s wearing a navy blue suit with red necktie.

Y/N: Ah, Ambassador Lenard good morning!

Lenard: Morning you two.

B/N: What brings you here ambassador?

Lenard: Oh nothing just check on you guys. Come on let's go to the mess hall to eat breakfast.

At the mess hall 

The Ambassador and the Commanders were greeted by the crewmen of the ship as they get their food and found an empty table.

As they we're eating, the 2 commanders was still yawning due to many paperworks they have done last night. Then Captain Rogers of the carrier came up to their table.

Captain Rogers: Good morning, Ambassador and Commanders we'll be arriving at Vale within 5 hours.

Y/N: That's good to hear, also good morning.

He nodded and gets himself some breakfast aswell.

At Vale

Ozpin has assigned Team RWBY and Team JNPR to show Enterprise, Hornet, Belfast, Cleveland and Laffey around Vale. When they first met, Ruby was drooling on their riggings while Yang tries to contain her.

Belfast: You have such a wonderful city Ruby.

Ruby: Thanks!

Laffey: ...sleepy...

As she was about to fall over, she was caught by Belfast.

Weiss: Is she always like this?

AL Shipgirls: Yes...

Jaune: So you guys were transported here along with your base island?

Hornet: You betcha!

Pyrrha: So you were made instead of being born?

Enterprise: Yes.

She then brings out her wisdom cube and shows it to Team RWBY and JNPR. 

Enterprise: We used warships until this cube right here turned us into humans to fight off the sirens who are threatning humanity.

They continue on showing them around the city.

In a secret White fang base

Adam Taurus and the White Fang are preparing an attack on Vale. As Adam is discussing his plans to his men, a siren came out of the portal.
