Two WW2 warships turned breakwaters wake up as cute girls just in time to fight an interdimensional invasion from a wormhole the 2011 earthquake created. This is the kind of fever dream only a local Fukushima ONA could pitch: real maritime history, real disaster trauma, real geography, all wrapped in mecha ecchi that has no business existing. Three episodes means it commits fully to the bit without overstaying. The actual emotional core, these ships spent decades protecting the coast that adopted them, now they're protecting it again, gets buried under transformation sequences. Watch it for the unhinged creativity. Stay because it's weirdly earnest about what it's doing.

Shiokaze and Sawakaze were destroyers in Japan's navy during the Second World War. After the war they were sunk on purpose to form part of the breakwater at Onahama Port in Iwaki, on the Fukushima coast, and here they appear as personified girls. In this fictional story, the 2011 earthquake disturbs space and time and opens a wormhole, and beings from another dimension pour through. An aspiring cyclist fights the invaders together with the two ships, who can change into robots. The result is a short ecchi mecha ONA that mixes local maritime history with sci-fi action.
