Gigguku
The world’s battleship girls joined forces against the Sirens, then the alliance SHATTERED over whether to use the enemy’s technology!

Father's Basement
A large ensemble of battleship girls and named factions can make the opening harder to parse than it needs to be. The core conflict is simpler. Azur Lane splits when the Red Axis embraces Siren technology, forcing former allies to fight over the methods they will accept against a shared threat.
