This is an injection-plastic kit of a science-fiction/anime item.
From the anime/manga series "Arpeggio of Blue Steel", in which the Earth is greatly affected by global warming and much of the world's landmass has been submerged underwater and fleets of sentient sea warships wipe out the remaining human naval forces, naming themselves "The Fleet of Fog". Each sentient warship has a human avatar.
This unique kit from Aoshima can be built to display the Super-Graviton Cannon as seen in the series. The model comes molded in blue plastic for the ship and includes clear parts for the display stand. Decals are also included.
