Hello everyone,
Here we are for another review. This time we'll review an erogè adapted into an anime that got a rather interesting premise. It is named Chaos;Head and is based over an erogè by Nitroplus.
Let's start with a synopsis :
Takumi is a high school student. He is withdrawn and is not interested in 3D things. In his town, a mysterious serial murder case happens and people get panicked. One day, when he chats on the internet, a man suddenly contacts him and gives him an URL. He goes to the website and finds a blog image that suggests a next murder case.... On the next day, it really happens....
Takumi Nishijō suffers from intense delusions as a result of his apparent schizophrenia and the extremely secluded lifestyle he lives as a hikkikomori. One day he accidentally stumbles upon a gruesome murder scene, a part of a chain of events called "New Generation." After this, his life gets caught up in these events, and he meets a bunch of increasingly insane anime girls with swords.
The premise as I said is quite interesting, and I thought that the power and the mad situation of the character may give this story some depth...
...but well I was totally wrong, the anime delve inside a pit of incongruences and rather evident problems that maked its enjoyment almost impossible.
All the power story is totally unbelievable and ends up generating plot-rule just to make it fall into pieces (The original Takumi who can't cure himself with a "deus ex machina" power that allows everything?! Auto-exclusion or something?! pfff...) and the new generation murders that mostly after the whole series still don't make any kind of sense.
The characters are your stereotypical one, all ending up following our main character for one reason or another, but they don't give enough growth in the anime. (Their backstory is not truly explained in detail)
The graphical quality is mostly high with some minor hic-cup during the series, but nothing exceptionally wrong. The animation is mostly consistent during the series and the opening and ending were quite interesting.
The sound quality is also high quality, there are a couple of famous seiyuu (like Eri Kitamura in Rimì's role) together with less famous one, but all of them do a nice job conveying the characters emotion.
One of the best thing of this anime series it the opening/ending songs. I listened (and I'm still listening) infinite time to the opening F.D.D. by Kanako Ito.
Concluding, , this isn't a bad series. It does have high production values and interesting premises, but I think it would have been a lot better if fleshed out in a 24/26 episodes anime with more depth on each of the characters backstory.
I do not suggest to watch it if you can't stand infodumping and gore as there is plenty of both into this series. (I hand-picked the less dangerous wallpapers. 
)
See you soon,
