Voice actress Ryoka Yuzuki (柚木涼香) keeps fairly busy, between video games, movie dubs, and obscure anime like Naruto, Nanoha, To Love-Ru, Queen’s Blade, and Kill la Kill. Publicity pictures show her to be an attractive woman, but that’s just the tip of the iceberg.
Starting at 15, under the name Ayumi Nagashii (永椎あゆみ), she did some acting, then as Kanori Kadomatsu (角松かのり), she did a lot of cheesecake and nude modeling (NSFW: 1, 2, 3), as well as B movies and this cute little NSFW clip (removed from this video). She briefly used the Nagashii name again for some hentai anime, before settling on Ryoka Yuzuki for her quite successful seiyuu career.
To end on an amusing note, the #2 link above claims that the term coined in the Nineties for idols who did nudes but not porn was ヌードル, which Google associates exclusively with Cup Noodle. Wikipedia redirects it to Adult Model, which isn’t nearly as fun.
