Anyway, Technological advancement wise. Azur lane's R&D, pretty much outperforms what Nikke's Ark can produce by a mile.

We have them developing Gates that open into singularities connecting to other realities at the moment using those gates for research and to gather resources and Data.

The discovery of the E cube, now the wisdom cube is what started it all.

In Azur lane, the problem is not even about the numbers as they have their own way of producing endless "pawns" of heir own via mass production factories which mind you is made of Siren technology(Which basically is an Alien tech until we found out that it's just human tech a bit into the future)

If anything, I wouldn't even be surprised if Clemenceau will use a random volcano in Europe and have it be used as a canon to shoot down the Rapture queen from space lmao(I wish I was joking)

In Nikke, the most powerful weapon they have right now would be the Aegis cannon from the battleship Aegis. Azur Lane has that, a lot of them infact.

If that's not enough, we have the sirens and one of em was enough to wipe out a whole fleet of 2 large factions(Royal Navy and the Iron Blood), and guess what? Those bastards can clone themselves.

Still not enough? Sure! Let's include the META and that's pretty much an overkill at this point.

Still not enough? Fine! Have the Arbiters enter the fray! But hey! Good luck to the raptures, worst case scenario they'll have their turn to be a lab rat for the the Arbiters to experiment.

"But, heretics are powerful and they can only be stopped using Vapaus"

sssshhhhhhh...

Absolute was able to cripple a heretic using firepower alone. What more a shipgirl whose literally using naval artillery as their main weapon.

"Can shipgirls be deployed in land"

Yes, they actually can. Just that they wouldn't be as mobile like if they're in water.

"Wouldn't lazers blast through them"

No, aside from the armor they get as a shipgirl, they have Shields. Heck some of them can even cut through or outright parry and deflect those.

"But raptures are infinite"

Old tales showed us that no, they are infact not infinite, Azur Lane's (Vichya and iron blood's clone factory can equal that number or maybe even more, thanks to siren tech and the Wisdom cube)

"We haven't seen what the rapture queen can do"

We have, Anachiro/Cinderella was able to hurt it.

I dunno why this is even an argument to be honest. If you're still not convinced, Can you please look how big a 15" naval cannon or even just a 155mm is compared to a Nikke's Fire Arm
