Rule 1. The Crimson Axis are now our allies. The Sirens are our enemies. Please remember that.

*this is the re-edited version of Chapter One, at the advice of starburst98

It was a peaceful morning at the Azur Lane Joint naval base. After the destruction of the Orochi, Azur Lane and the Crimson Axis had begun to repair their diplomatic relations, with talks of an alliance starting once again. As a result, a fleet of Sakura Empire and Ironblood forces were expected to arrive at the Joint Base to join the combined forces already stationed there. Everything was going according to plan.

Then the base's air-raid sirens went off.

USS Long Island, still in what appeared to be her off-day attire bolted from the dorms in an unusual display of speed. Seconds later, she had several SBD scout bombers in the air, much to the confusion of several nearby naval personnel and kansen.

Until they realized where her aircraft were heading.

IJN Zuikaku was excited. Her longtime rival, The Grey Ghost was stationed at this very base! What luck! She could finally challenge her to a duel! She could finally prove herself to be the better carrier-

"Wait. Why are the air-raid sirens on?"

The sound of aircraft overhead made Zuikaku, in a reflexive action of stupidity, look up.

The resulting action delivered a bomb straight into her face.

Eyewitness reports would later state the explosion was both spectacular but also looked incredibly painful.

Panic broke out amongst the combined Sakura Empire-Ironblood fleet. Shoukaku went straight for Zuikaku, Admiral Hipper began screaming something about filthy Americans in German, Prinz Eugen's anti-air littered the air with flak while Ayanami just stood there. The other ships gathering into a rugged anti-air formation as all hell broke loose.

With a blank stare, the destroyer simply chose to ignore everything going on.

"What is happening... dess."

A few minutes later, the sounds of angry shouting and the pained wailing of Long Island could be heard all over the base.

Admiral Lillian Nimitz, commander of the Eagle Union, stared at the battered and bloodied form of Long Island, who lay in a literal pile on her office floor. The shut-in escort carrier had apparently been unaware of the new changes in relations with the Crimson Axis and had activated the base's alarms when she saw the approaching fleet. How does one not know about such events? Admiral Lillian had no clue.

"So. What have we learned today?" She ground out. Annoyance coating her voice.

Long Island mumbled into the floor.

Admiral Lillian sighed.

"Shall we send her to the repair docks...?" Her secretaryship USS Enterprise asked.

The Admiral merely nodded.

"Please inform her that her punishment will be deductions from her paycheck for the repairs of all injured parties and that next time, she should check the base notices."

"...Of course." Enterprise sighed.

Hello everyone! Thank you for reading the first chapter of Things involving Kansen that are no longer allowed!

For those who know of CV12Hornet's story "Things involving shipgirls that are no longer allowed" I took inspiration from the said story and wished to write an Azur Lane variant of such! While I do not have anywhere close to the amount of writing skills they possess, I do hope I can keep you all entertained! For now, updates will be irregular, as I write these 'rules' as they come to mind. If you have any rule idea, please send them my way! Thank you~! Yuuki signing out for now!
