When Takao was about to be sunk/Killed as a target ship until a Female Knight with golden armor gave her some time to escape and from there she was hunted by Eagle Union and Royal Navy shipgirls,
But she fled from Fuji Mountain and was about to die...
As Unryu left She summoned her and stands at it's fight deck and then pulls out a phone and puts some earphones on her ears and plays a song
As she played this 6 Shoki Fighters/Kamikaze Aircraft appeared at her fight deck and because of this she steps aside so that the planes could fly and then 10 Mitsubishi A6M3 Zero Fighters, 8 Aichi D3A Val dive bombers, and 8 Yokosuka D4Y3 Torpedo Bombers followed the Kamikaze Aircraft and made a formation to protect the 4 Kamikaze Aircraft
Operation 鋼鉄ノ鳥 (Kanji: Kōtetsu no tori, English meaning: Steel bird) also known as Steel Bird Protocol is a operation/protocol created by Takao incase Enemy ship's survived from The Operation attacks that Takao made against there enemy(Expect that you'll see this song Video again in the near future As Takao has a plan to humiliate Enterprise once Again)
At the 5th Carrier side
We could see The 5th Carrier Division on there own ships as Nagato tells them what Kamikaze planes could do and needless to say they were both shocked including the ones in Nagato's side
They were used after the 5th Carrier Divisions death in The Battle of The Philippine Sea and Battle of Leyte Gulf as suicide planes in hopes to sink the enemy during the Pacific war
With this information is hand The 5th Carrier Division aimed all of there AA guns at the sky incase enemy planes came and to shoot those planes immediately
Until Unryu's squad saw and heads to the 5th Carrier Divisions Ships and in response The 5th Carrier Divisions AA guns lighten up the sky with Black smoke alarming the Crane Sisters and so they summoned there planes to intercept them and summoned there rigging to dodge the Kamikaze planes
Until a cloaked shipgirl Appeared and was about to hit Zuikaku with a mace only for Zuikaku to dodge it in time
and from there the Shipgirl removed her cloak revealing herself

Zuikaku: So it was you and your other friends that attacked us, Unryu!(They met once before the Battle of the Philippine Sea)
Unryu: Correct Ms. Zuikaku me and many others attacked you since your about to Attack Pearl Harbor at Eagle Union and so we decided to Pearl Harbor the mainland instead
Zuikaku: How did you-
Unryu: That's secret you have to solve by your own but it would be best if you look at your sisters condition
as she said this Zuikaku turned her head to see her sister in danger but Unryu get the opportunity to pull out two green paper cut like planes and throws them straight to Zuikaku and the 2 paper cut plane turned into 2 Shoki Fighters/Kamikaze Aircraft
As Zuikaku saw this she used her sword to slash them and from there she could hear her sister screams of pain as Shoukaku got hit by a Kamikaze and a torpedo
as Zuikaku rushed to her and from there all the planes that Unryu sent returned back to her and from there she spoke
Unryu: It's a shame that I have to hide the truth to you but let me say this "The Second World War was set up to humiliate us"
Zuikaku: What do you mean Unryu?
Unryu: You'll learn the truth soon, and since I'm a merciful Person, I'll let you go unless you also want to be hit by Kamikaze planes?
and since Zuikaku is in a risky position she decided to leave and return to the Sakura Empire
and from there Unryu called Takao
Unryu: I've prevented them from Following us Takao order's
Takao(On the Radio): Return back to Base we need you for Operation Dethrone
Unryu: Very Well
and from there Unryu left to return to the fleet
Unknown to her A Sakura Empire Submarine was following her, but also Unknown to that Submarine, Unryu know where she is but it was all part of Takao's plan to achieve there main objective
