Humans have been polluting the ocean for a long time, carelessly pouring their garbage and desecrating the waters that many creatures call home. The denizens of the sea have suffered at their poisoning hands. Finally, one certain squid has had enough and vows to punish the humans' selfish actions.

Possessing all the fearsome abilities of a squid such as powerful hair-tentacles, the ability to spit ink, and even use bioluminescence at will, Ika Musume takes it upon herself to rise from the depths of the ocean and exact revenge upon humanity! She surfaces at a certain Lemon Beach House, a restaurant managed by the sisters Eiko and Chizuru Aizawa. Thinking them to be an easy first step toward world domination, she immediately declares war against them, only to find out that she is, quite literally, a fish out of water! To make things worse, she destroys a part of a wall of the beach house in an attempt to flaunt her squiddy superiority and is consequently forced into becoming a waitress to pay the repair costs. Beached for the time being after tasting a thorough defeat at the hands of the Aizawa sisters, Ika Musume is forced to put her plans for world domination on hold.

Despite these setbacks, Ika Musume soon finds herself right at home in her unexpected position as Lemon Beach House's newest employee. Wacky and hilarious, Shinryaku! Ika Musume follows her brand new life on the surface as she makes precious memories and meet lots of new people. With her newfound acquaintances, Ika Musume is looking to take the world by storm, one squid ink spaghetti at a time!

Cute squid girl. Classing Ending animation. For opening is so-so. Both opening and ending song is not bad. The story is good, balance of the comedy and SoL. Some episode are predictable, for SoL watcher of course. As for character, each of them are unique. they have their roles well within the story. For Art style, like other SoL anime, simple and classic. Realistic? Definitely not, it's a Squid Girl.

For me, i enjoy this anime.
Recommended for you to spend your days in chill sofa with big TV and snacks. Not recommended for Action fans anime, Obviously. For them, they will say "boring anime".

Mixed Feelings
'Shinryaku! Ika Musume' is an extremely wholesome and cheerful show with a touch of misanthropy. Things can get pretty goofy or whacky, but there are also times where it might make you cry (in the good way). The characters are oddballs, but that's what makes them so lovable. Squid girl's attempts to take over humanity are as cute as they are amusing. It might even motivate you to take better care of the environment. This show may be too childish for some audiences, but it's quite heartfelt and positive so you might like it anyway. IMO, this show is pretty underrated.

Preliminary (10/12 eps)
Ok, so just 2 more episodes and this anime is already nearing its end, so what can I say about this anime? Well, let's put it this way according to how I rate this anime:


Originally, the plot of this story is about nature fighting back against humans who pollute the seas with garbage and with the help of squid girl Ika Masume and her so called invasion force of half human and half squid, which,by the way she seems to had forgotten bring it along with her at the start of the anime- talking about letting a girl do a grown-up's job. But,only to get ...
