Its release date is currently unknown.
In the story, a "Fleet of Fog" loaded with super weapons suddenly appear all over the world. Without the ability to withstand this fleet, humanity was defeated and could no longer travel the seas. 17 years after the devastating naval war, Gunzō Chihaya and his friends somehow commandeer a "Fleet of Fog" submarine and rename it I-401. Together with Iona (I-401's "mental model" or physical incarnation in humanoid form), they take on the "Fleet of Fog."
Quick off the confirmation that Ark Performance's sentient battleship sci-fi manga Arpeggio of Blue Steel is set to be adapted into anime, Flying Dog, whose domain registration originally prompted anime rumors, has posted a promo.
Seiji Kishi (Angel Beats! , Persona 4 The Animation) will direct the SANZIGEN (009 Re: Cyborg , Black Rock Shooter) produced series, with Makoto Uezu (Devil Survivor 2 The Animation, The Qwaser of Stigmata) penning the scripts.
