As the second coming of the titular Dogtooth Angel and the reincarnation of Michael, Zsaciel is an extroverted, starry-eyed, adventure-seeking little bugger who wishes to travel the universe and befriend people across the world. He believes happiness is fulfilled when spent in the company of others. 

Looking for a young male/female doing a young males voice. I imagine he sounds like your wide eyed, husky cough drop voiced little brother who wants to do everything with you. Like Jason Marsden (Max Goof), Greg Ayres, or a higher pitched Dean Winters.  Goes into a deeper register when he goes into humanoid form.
