I will just use it in a positive way, thus its synonym is "gives you goosebumps".
The seiyuu who gives me goosebumps every time I hear his voice is
Try to notice his breathing pacing when he does his voice acting in Drama CDs, even in anime...
(Well, only girls will understand what I mean here though. -__-)
He's got a long list of characters portrayed in anime, so he is a real veteran now.
Anyway, here are his pictures:
HELLO THERE CAMERA-SHY MIKI-SAN
(a) He's with Morikubo Shoutaro while he covers his face.
(b) With Ookawa Toru while he covers half of his face. Yey to the Hakuouki poster too.
(c) Covering his face with that (what is that? wwww) with Nobuhiko Okamoto in front of a Dummy Head Mic.
This is from Hakozume Drama CD.
(d) With Kamiya Hiroshi while he covers his face with a manga.
Hard to find shots since he is usually hiding his face.
He has aging features, but that doesn't affect his talent as a seiyuu. After all, what counts the most to him is his voice. He is famous in their industry, he doesn't have anything else to worry.
Hontou ni Arigatou Gozaimashita.
Thank you very much.
