(Source: Entame) [Sorry for earlier erroneous translation! thanks to the person who left the comment for me!!] The 4th episode of Kimura Takuya's new dorama, Mr Brain, aired on 13th June 2009. Kamenashi Kazuya was the guest star in Episode 3 and that episode was the only episode that did not break the 20% ratings ceiling.
The ratings for KimuTaku's new dorama so far is as follows:
24.8％→22.0％→16.3％→21.0％
The episode with Kamenashi was 16.3%. This is bad news for him!!
