By 2039, global warming had caused sea levels to rise and large amount of territory to be lost. As though in response, a mysterious group of warships clad in mist, "the Fleet of Mist," appeared in every corner of the ocean, and began attacking human ships. In spite of humanity mustering all their strength, they were utterly defeated by the Mist's overwhelming force. All of humanity's trade routes were blockaded by the Fleet of Mist, their political economy was destroyed, and the human race was steadily beaten down. Seven years later, the Fleet of Mist's submarine I-401 appears before cadet Gunzo Chihaya. The humanoid life form that pilots the sub, who should be their enemy, is instead offering her services to mankind.

Loved the animation, loved the ships and character design. The opening song is good enough to listen to repeatedly. Another thing I loved is that this has the set up to be a harem (1 guy, tons of powerful, attractive girls) but doesn't turn into one. There's only 1 love triangle and all the other mental model girls have their own motivations. The mental model characters are fleshed out very well and think is one of the best female supporting casts I've seen. Iona is probably the best character, with all of the ship mental models following closely second.

On the surface Arpeggio has a few detractors but if you allow people to finish airing their subjective complaints about how CG never blends well with anime, the harem genre is overused and how they don’t want to be made to remember complicated words like Super gravity Cannon and Klein’s field, you’ll find that Arpeggio has a decent story, a setting with rich possibilities heavily untapped by the anime world, interesting characters and an all but obvious moral lesson at the end.

Aoki Hagane no Arpeggio: Ars Nova Full Review

I would say that Aoki Hagane is one of those dark horse anime this season. Not many people watched it, maybe because they didn’t like the art style or maybe just the idea behind battleships. So, is this a worthy investment of your time? Let’s take a look!

Note: There will be minor spoilers.

Story (9/10):

The story of Aoki Hagane is broken up into two parts. First, is the battle between humans and the forces of the Fog. This is basically the universe it is set in, and our hero, Chihaya Gunzou, somehow manages to obtain the power read more

"It's a carnival!" -Maya

There is no better line to describe the enjoyment I got out of this seires. Unique and thoughtful, I would recommend this series to almost any anime fan.

Aoki Hagane no Arpeggio could be compared to a hidden jewel. The unique art style and idea of navel combat may drive many viewers away, but any who decide to try it out will almost certainly find a high degree of enjoyment.

Story 9/10

The entire plot was focused around one main goal: getting the vibration torpedo to the US. As such, little time was spent foreshadowing unexpected narrative twists. This doesn't mean the series was without read more

Both have the same Naval settings.

Both involves war in the seas.

Both also have the same situation were humans were driven out of the sea.


The enemy in one anime is more of a hidden type. while the other anime, the enemy is known.

One has an extra sci-fi genre, while the other has supernatural, comedy and harem.

The art in one anime has a futuristic theme, while the other one has a bit of retro theme.

Similar 3D animated cell-shaded look. Both are about a boy, while initially disliked by many, later achieves heroic deeds; even if they made some enemies along the way.
The protagonists of both series gains a powerful vessel to board (a space mecha in Knights of Sidonia, and a sci-fi future-spec'd submarine in Arpeggio of Blue Steel: Ars Nova) to fight against a relatively unknown enemy bent on destroying humanity.
the similar thing between the two anime , is that the main characters try to rescue Humanity from extintion cause of a strange kind of enemy showed off suddenly.
This show reminded me of Mouretsu Pirates in a way. If you enjoyed this i think you might also enjoy Mouretsu even more.

Girls controlling ships (well in mouretsu's case space ships)

Fight in Oceans/Space

Don't want to tell too much just give it a try if you don't like it in the first few episodes then whatever.

1. Enemies from unknown origin take over the seas.
2. Humans fight back.

KanColle: More lighthearted + sorta dull aside from some cute slice of life. Fine for spending free time on if you have nothing else to do. Treat like any slice of life.
Ars Nova: Exciting, intelligent, better fights, better usage of CG animation, better character development, better "powers", etc. Main downside is less yuri. I don't really care much about the ship girls thing, but this anime was a real "page-turner" when it aired. KanColle was more like "oh the next ep is out".
Both shows have a strong focus in intense warship battles and have beautiful girls as main characters (as well as a few males).

- Starship Operators uses CGI for battles, while Arpeggio is a full produced CGI anime. You can see a huge technical difference between.

- Relationships are well portrayed in Arpeggio. Starship Operators also has interaction between its characters, but it seems a little bit odd.
