TBS' Mr.Brian??? (somewhere like May 23rd?)?

Is there such a thing? I'm so confused... Gackt said on his blog, "5月23日スタートのTBSドラマ「MR.BRAIN」(土曜19:56～)に、Gacktの出演が決まりました。

Gacktは第2話(5月30日OA)に登場します。

ご期待ください！ "

He should be on an episode of whatever this show is on May 23rd.... But I can't figure out what this show is!

TBS is a station in America, but I can't find information of them having a "Mr.Brian" (their scedule (sp?) only goes to May 11th though)

Gackt was in America for the Bunraku filming, for i all know he might have done some for this! (but I kinda doubt it)

If not, is this a Japanese TV station with the same name as one here?

... O_O;

does anyone know about this drama? What country does it air in, I can't find any results for it when I search.
