Adding animations to models?

I found this Ayane model from dead or alive, and it works fine, but as a player model, it has no animations, and just walks around in somewhat of a “T” shape. I was wondering if anyone can add the normal animations to the model. I tried to do so, but have no experience and continuously failed. I would really appreciate it.

I uploaded the model into a .rar so people can take a look.

Thanks in advance
