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.

Before deciding if you should watch Aoki Hagane no Arpeggio: Ars Nova, you should probably ask yourself if military science fiction is your type of anime. Military science fiction often takes the idea of military but also fuses it with supernatural themes with flavors of science and artificial warfare. There are a lot of ideas that plays around with military sci-fi including alien invasions, mecha, or space wars. So what happens when you take a bunch of mental models that resembles the characteristics of female characters and puts them into total warfare? Simple. You get Arpeggio of Blue Steel: Arsa Nova.

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.

In the year 2039, the combined naval forces of humanity suffer a crushing defeat at the hands of a military force with weapons technology that far surpasses their own. The fearsome assailants? A group of heavy warships, termed “The Fleet of Fog,” who are commanded by “mental models,” robot-like representations of the minds of the battleships that take the physical form of little girls dressed in frilly clothing. Fast-forward seventeen years, and one of these mental models, named Iona, approaches a human naval cadet named Gunzou out of the blue, offering herself (and, by extension, the advanced Fog submarine she represents) to Gunzou to command. read more

Anime: Kantai Collection: KanColle
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".

Anime: Tactical Roar

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.

Anime: Mouretsu Pirates
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.

Anime: Shingeki no Kyojin

Anime: Sidonia no Kishi
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.

Anime: Zipang
Both deal with war
Both deal with ships

One deals with friendships and bonds
The other deals with alternative histories and complex characters.

If you liked arpeggio you'll probably enjoy Zipang.
