I mean yes; the Chibi versions of the characters may be somewhat new to some people and it may cause haters to raise and comment about it but still!
We should look at the plot!
The plot is based on the 12 Chinese zodiacs and the story of how the cat tries to fit in among the zodiacs.
The plot itself is somewhat unique; I mean who would think of a competition that is held once in a few thousand years for the 13th zodiac place?
That's plenty unique if I must say!
There are also times when the anime goes past the line that they shouldn't pass (I mean it they start talking about recap episodes) which is funny so no problems there
Although it is not fully focused on explaining the reasons behind Nya-tan's motives until much later on; the anime keeps the viewers distracted by providing us comedy
I swear this anime can be categorized solely as a comedy anime and I don't think anyone would complain.
BUT the story starts to go into detail about Nya-tan towards the end (sadly) but none the less the explanation was necessary; especially with an anime like this which already started with the present setting from episode 1.
I still find it amazing how creators can summarize the plot line of the series into one episode.... It amazes me till this day....
For a 12 episode series it ended perfectly!
Although it felt rushed the series was none the less interesting and in addition was hilarious!!
Comedy lovers will love this anime (If they don't mind how the characters transform into Chibi versions of themselves)
