Yeeeep, it's Nenohi's fault.

Murasachan: How come whenever Poi-chan throw me in a attack i get drowned or rode like a surfboard, yet she throw a torpedo and get a cool explosion.

And that's why the base got obliterated.

Explosion ending, a truly Kancolle manga...

i willl frrryyyyyyyyy yea

Maybe they should just start making the naval base from more damage-resistant materials?

Then again, maybe it's cheaper to use crap materials and just rebuild constantly...

It probably was blast resistant to begin with, but after the first explosion they could only afford the cheap stuff.

That was a Sanshiki, wasn't it?
