かつての英雄。

A mysterious, decaying battleship submerged in an unusually clear sea, with sunlight penetrating the water more broadly. The image is highly realistic, capturing the intricate details of the deteriorating battleship and the widely dispersed sunlight. The sea water has an extremely high level of transparency, making the underwater environment vividly visible and beautifully illuminated by the sun over a wide area. The aspect ratio is 16:9.
