Incisivis: I love the way Megumi Ogata screams in this shot. Positively chilling.
Reichu: And she has a rather disturbing talent for it, as well! One wonders how the woman avoided permanent vocal cord damage.
Incisivis: I think it's rare that a VA's performance can be so stressful there's permanent damage, based on my limited experience. It usually seems that some actors with difficult performances get pushed to their limits in a session and have to stop, but are fine later (this happened frequently to Richard Horvitz while recording for "Invader Zim"). Although, the first dub actress for Excel from Excel Saga had to quit because the hyperactive performance would have damaged her vocal cords. Don't know of any Japanese cases, but I'd imagine things are the same.
