Arpeggio of Blue Steel

蒼き鋼のアルペジオ

Aoki Hagane no Arpeggio

In the seventeen years since the enigmatic and invincible Fleet of Fog materialized and dominated the world's oceans, rendering intercontinental and inter-island travel obsolete, humanity has yearned for liberation from this aquatic tyranny. Despite the persistent desire for a rebellion against these uncrewed ships, there was no sign of salvation—until recently. The invention of a weapon capable of harming the Fog Fleet has ignited a glimmer of hope. With the vital data and prototypes needing to be transported from Japan to America for manufacturing, the submarine I-401 emerges as the sole viable option. This submarine, alongside its humanoid representation—an AI known as Iona, who presents herself as a youthful girl—was once part of the Fleet of Fog but has now decided to ally with humans. Under the leadership of Captain Chihaya Gunzo and his team, the I-401 stands as the only ship controlled by humans that can traverse the seas unhindered. However, it adheres solely to the orders of its captain, who operates independently.
