The anime voice acting industry is an extremely emphatic creative field. The craft of nurturing outstanding vocal performances is never taken lightly, and talented voice actors, or seiyuu, are worth their weight in gold. With over 130 voice-acting schools actively training new voice-acting stars across Japan, aspiring seiyuu face fierce competition to get into this niche of the entertainment industry. In anime, some of the most prolific seiyuu get roles due to the archetypical nature of their voice, typecasted only as loud genki girls, soft-spoken stoic anti-heroes, or expressive shonen protagonists.
