C cube was really rushed in the story, is like if they knew they were not going to make a 2nd season, and they wanted to throw a lot of content in just 12 episodes.

The story at first is really great, but it goes down every episode, because is not consistent, is like there are three different stories on just 12 episodes, the first story was great, was dark and violent and the action was the best in that story, the 2nd one was fine but it wasn't what i expected, like it slowed down the things and less violent and less dark and the read more

C3 centers around a boy named Haruaki Yachi who one day recieves a black cube from his father. His father sends him cursed intruments to try and make him break the it because he is resistant to curses. However the black cube is actually a girl named "Fear" and she is a type of intrument, a "Fear in Cube". She suddenly starts living with him, much to the dismay of Haruaki's childhood friend Konoha.

However as the story progresses on, it develops into something much darker. Turns out that there are other people who wants the " Fear in Cube", and they come after Fear. read more

I'm generally more positive regarding my views about series, so I'm not gonna flame the series.

Also, note that i am reviewing this long after it's release, so there are newer anime that serve as reference points as well.

But i will describe this series as wasted potential at very least.

based on that

I'll begin with the plot, which revolves around cursed artifacts taking human form and the overarching plot in the series is about the role of the curses and how to break them or something of that level. My vague and uncertain description of that overarching plot comes literally from the fact that it read more

Why didn’t I drop this?

[Contains vague spoilers, then again, it's so predictable a caveman could do it, also contains some offensive language]

C³ is best described as an atrocity then again, that might be considered a generous title. This would be the “ideal troll” series to give somebody to watch. It’s not very good in storyline, and the characters are the aggravating type of cliché. It follows the generic harem law of everybody falling in love with the average dude, and it offers incessant and redundant fan service. The series basically follows this extremely unique and innovative storyline:

Boy meets unique and strange girl, strange girl is read more

Anime: Kore wa Zombie Desu ka?
Both have characters with supernatural abilities which are very similar to each other. 
reportRecommended by shadowsword
Anime: Dansai Bunri no Crime Edge
Both shows have people fighting using, or being, cursed instruments/tools. They also look cute at times, and very violent at others.  
reportRecommended by Emathejester
Anime: Dragon Crisis!
Both of these shows are about artifacts. Dragon Crisis! has them in a more positive light, while C³ has them in a darker light. But some of the objects actually have a life of their own.

Anime: Itsuka Tenma no Kuro Usagi
Bright colors, a chaotic plot line along with a chaotic cast of characters.

Anime: 11eyes
the fights are pretty simular.
In C³ the people are the cursed objects, in 11eyes they are within the person.
A lot more.

Anime: Akikan!
Girl comes out of a strange object with super powers
Boy conveniently lives alone and girl stays with him
Ecchi elements galore

Plenty more to list but you get the idea.
