SKE48 member Matsui Jurina will be appearing in the "Kagi no Kakatta Heya SP" due to be shown via FujiTV on 3 January 2014 at 9pm. The SP is a continuation of the hit drama series shown during the spring 2012 season and features Arashi's Ohno Satoshi as a security systems expert Enomoto Kei who works with lawyers played by Toda Erika and Sato Koichi to solve difficult mysteries.
Matsui who is only 16 years old, will be playing the new secretary of Serizawa (Sato) who is 21 years old. She commented that it was rare for her to wear such clothes typically worn by OLs and that it was difficult to say lines containing words which she doesn't say normally. However, it was a great experience to work with the crew and cast.
The guest lineup for the drama SP was also announced where Fujiki Naohito, Kuroki Hitomi, Sano Shiro and Okada Yoshinori will appear in the sequel.
