Kirill is a very special character, despite not having many lines in the movie he is certainly one of the most important characters for the plot and is one of the three main orcas of the short movie.

He is a fairly young character that could be classified as a 13-15 year old human, so make sure your voice tone fits that.

Think about stitch when auditioning for him, his accent is really weird and he can hardly speaks english, sometimes, even speaking some type of giberish.

Kirill does not speak english very well and most likely has a croocked, weird accent in russian or any other northen europe language.
