Trying to find a Japanese Cartoon

[Kelpie]

Dear Japanese Cartoon Experts,

 

I'm trying to find a Japanese Cartoon that featured a young Sorcerer in the ancient Japan era. This young sorcerer has a guardian which is cat lookalike creature.

 

Someone told me it is the Kekaishi (结界师). An example is shown here at http://www.youtube.com/watch?v=NmCDDFMkANI .

 

But, still, this is not the one that I came across. The one that I once watched was a sorcerer whose grandfather is a supreme sorcerer. He appeared to be powerless at 1st but his potential slowly released with the help of a cat like creature. This cat looks more stylo that the above example.

 

Do you know which cartoon am I referring to?

 

Please advise me.

 

Thank you very much.

 

Regards,
