Oh, I see now. It's Yaguchi, Kago, and Inaba, not Mika, but all they're doing is the Japanese dub. Less exciting now, but still obligatory for a Yaguchi/Kago completist, I guess....

Now I'm thinking that I may have seen it mentioned in a Wiki article once upon a time and then forgot about it, since all they were doing was voiceovers.
Another recent purchase: A local used bookstore had a bunch of old Japanese dorama series on cheap Malaysian DVDs and VCDs, so I picked up Beauty 7 from 2001. It's an 8-VCD set with Chinese subtitles (no English), but it only cost me $4.79. It stars Uehara Takako (SPEED), Fujii Takashi, Itō Misaki, and Nakazawa Yūko. Whoever prepared the text on the packaging had absolutely no knowledge of kana, though, since the Japanese title appears as ビヱーテイーセづソ!
