An Abyssal Lighthouse? But honestly, a Neuroi came first into my mind.

It's Tartarus!

It's Abyssal Fubuki making a statement. "THIS IS HOW BIG YOUR BONER WOULD BE IF EVERY TIME YOU BLUE-BALLED YOURSELF MADE IT GROW A BIT MORE!"

Is that how they're manipulating the weather?

If so, how is it that they haven't taken over the world if they got technology like that?

Could it be...the rumored Neo Armstrong Cyclone Jet Armstrong Cann—

the Neuroi has arrived shoot the CORE FUBOOTY

Is this the no-good thing revolving lantern ?

I told you it wasn't just a bunch of destroyers that Fubuki could solo.

That's a damn installation. Come to take Tokonatsu-kun home to his true family.

Ask not for whom the light shines; it shines for thee.

This seems like something that belongs in the Fate universe... "Noble Phantasm: Lighthouse of Alexandria!"

It should be mentioned that the "no-good thing" was meant as an alternate reading of "revolving lantern", not as some sort of title.

Oh God, it's the Washington Monument! Run! Run!

A lighthouse is a part of the shipping industry as it was design to keep ships safe. Thus this is a Shipping Tower, put in place to keep the shipping of the Admiral and Fubuki safe.

Its so large now because the shippers are frustrated.

It's the Clinton Monument!

That or the Iron Giant came late.
