First, their 14th single, the title yet to be announced, will be the theme song for Tamamori's drama, "Seishun Tantei Haruya". (The drama was announced back in spring, and will start airing in October on NTV.) It will be released on October 14th.
Their 15th single is called "Saigo mo Yappari Kimi", which will be the theme song for Tamamori's movie, "Raintree no Kuni" and is written by the well-known music producer, Tsunku♂ (つんく♂). It will be released on November 11th.
Tsunku's comment for the song - "It has become a song that will warm your hearts and it's filled with members' passion, innocence, and attractiveness, so I'm happy with it. It has become a powerful song, overflowing with kindness - it is more than the love song I had imagined it'd be."
Kitayama - "I'm just really amazed. Tamamori being the lead actor for both works is amazing too."
Tamamori - "I'm happy that I can be a part of both works as well from the music side, through the theme songs."
Fujigaya - "We're going to convey our feelings of gratitude with all our might."
There may be more details in the newspaper, but we have to wait a bit for the full articles.
