As Y/N charges up his 4 railguns, everyone begins to distance themselves from him.
Tester: I dont think so.
She lunges herself only to get an uppercut from Alan's gauntlet and send her flying.
Tester: Argh! You little brat!
Alan: ....
She gets up as she rubs her chin.
Tester: Why you...
As she fires her laser cannons at Alan, He launches some UAVs and dives down to the depths to evade her attacks. As she was finding him through her sonars, Alan surfaces himself behind Tester and blasting her further away using his auxiliary railguns, while his UAVs attacks her aswell.
Tester: AHHHH!!!!!!
Y/N finally done charging his railguns.
Y/N: Fire!
*Skill Activate: Ultra Rail Salvo*
Then 4 of his guns fire a blue beam at Orochi penetrating its sheild like it was nothing and hits the hull of the ship. After it hits the hull the ship begins to explode from the inside.

She turns to Amagi who is also not happy.

Amagi then turns to her with an evil grin on her face.
Akagi: Nee-san, is there anything wrong?
Then Amagi changed her appearace into a siren.

Akagi eyes widen to see the Empress of the sirens.
Akagi: What's the meaning of this? What have you done to Amagi?!
Empress: Oh we didnt do anything cause she's still dead, I only used you to advance our plans. Since Orochi has failed, your service is no longer required.
She fires her laser guns at Akagi, blasting her off the ship.
Christine: Oh, she got backstabbed.
Zuikaku: Akagi senpai!
Kaga: Nee-san!
Empress: Well...I have no choice but to destroy all of you with my bare hands.
A bunch of Portals appeared out of nowhere and more siren ships came out of those portal and humanoid sirens. Y/N then readies his sword while Christine brings out her daggers.
Y/N: Ready sis?
Christine: Always ready!
Y/N: How about you little bro?
Alan nods as he raises his gauntlets.
Then Shipgirls from both Azur lane and Crimson axis stands beside them.
