It's been announced that Utada Hikaru will sing the theme song for TBS's new drama 'Saiai' to premiere in October. 

'Saiai' is an original suspense love drama produced by Arai Junko, directed by Tsukahara Ayuko, and written by Okudera Satoko and Shimizu Yukako. It will star Yoshitaka Yuriko as Sanada Rio, a businesswoman who becomes a witness of a murder case, Matsushita Kohei as Miyazaki Daiki, a detective pursuing the murder case, and Iura Arata as Kase Kenichiro, a lawyer who defends Rio.

The title and track will be revealed during the drama's first episode. Producer Arai commented, "I had even dreamed about Utada-san singing the theme song. I created the proposal while listening to 'SAKURA Drops' endlessly, so I am thrilled that Utada-san has written the song!"
