Sexy Zone will release their 21st single "Natsu no Hydrangea" on August 4. 

Written and composed by Hata Motohiro, the title track is a summer song that will be used in Fuji TV's upcoming drama 'Kanojo wa Kirei Datta' starring Nakajima Kento and Koshiba Fuka. After reading the drama's script, Hata compared the heroine to the hydrangea that blooms beautifully in the city even when it rains. On the song, Nakajima commented, "I feel like I've encountered Sexy Zone's most ultimate love song," and "Let's make the 'hydrangeas' bloom this summer!"

The single will be available in three different types: Limited Edition A, Limited Edition B, and Regular Edition. The Limited Edition A DVD will contain the music video and making footage for "Natsu no Hydrangea," whereas the Limited Edition B DVD will include a special variety footage.
