Story: 2/10
EASILY THE WORST PART OF THE ANIME. It goes from something simple of cute girls learning how to pilot battleships to them fighting rogue ships from their school with the STUPIDEST reason ever...not going to spoil it other than a virus but the reason how they get the virus is really, really dumb.
Each episode has roughly 15 minutes of nothing happening with some action sprinkled in. The action scenes are kind of interesting but other than it's just a slice of life on a battleship.
I also wonder some reasoning for things like how and when did Japan sink? They do mention a "war" that caused the country to basically become flooded but when did the war take place? With who? For how long? Why do all boys schools only learn to operate submarines and all girl schools only learn to operate battleships? Do they not want girls in subs and boys on ships? Why were high school students given very powerful battleships (You will see what I truly mean towards the end).
Art 7/10:
Things like the characters and boats look pretty, so I can't hate on the art here. Pretty enjoyable on the eyes.
Sound 7/10:
From the fire of the cannons to the roar of the boats, the sound here is quite good. Music is ok, nothing too memorable. The OP is more or less generic anime music that is supposed to get you excited which is fine. The ED is forgettable really. Overall the sound is nice.
Character 3/10:
I don't give a damn about any of these characters. There are too many they try to make important in too short of time. Then, they try to go through the backstories of Shiro, Mike and Rin (fun fact, Rin's seiyuu is Yurika Kubo, famously known as Hanayo Koizumi from Love Live! Funny enough she's voicing the same name of her best friend in the show but like Hanayo in Love Live, Rin here is very shy). Honestly I wasn't invested in any of them so why they are training to become Blue Mermaids does not interest me in the slightest.
Enjoyment 4/10:
At first I enjoyed it but then after the VIRUS I was just under the impression of how dumb this really was. It felt more like a chore to finish which is never good.
Overall 4/10:
There are many anime involving cute girls, there are many anime which involve cute girls doing X. Honestly speaking there are many anime which can fulfill your cravings for cute girls anime girls and there are plenty of anime which involve cute girls doing various things. Save your time and go "full speed ahead" away from this show.
