This anime is about Chihaya Gunzou and his friends along with their submarine I-401, a.k.a Iona who is a traitor to the Fleet of Fog, which is the main antagonist of the series and they're not human, but they are physically human, and they view themselves as weapons.
Chihaya Gunzou and his crew take on a few jobs that involve taking down the Fog while helping countries reestablish connections with other countries since the Fog's involvement to blockaded all the sea ports for some unknown reason. Battling with other Fog ships who follow the admiralty code (like a set of rules for the Fog) Chihaya Gunzou indirectly changes the female Fog members (cause ships are female) point of view on themselves and their reason for doing what they do.
There are some reasons that this review isn't getting a 5/5. Character development. I mean there is some character development, but I don't see it for Chihaya Gunzou's crew I can barely remember their names. It's like they're there, but they aren't there.
They're just people who have roles on the ship, I mean their things do give a perspective on what they like, but there's gotta something more to that. In the first episode they introduced Chihaya Gunzou and Iona respectively with a bit of background history, but that's it.
So I hope that the anime sheds some light on that, but that's just me.
I'd recommend this to those who like action, awesome animation, and a gusty main character who takes many unpredictable risks.
