@Shien it's identifiable as male but not overly masculine. If I can I'll find a clip of the kind of voice I imagine he has and post it so people have an idea. Though in the meantime it's rather soft and...I can't think of any other adjectives that don't sound horrendously feminine.

This is the closest I could find. His voice is like the character 'Break' in this. The short white haired guy who appears from under the table.
