TBS' drama adaptation of "Koizora" now has its leads confirmed. From more than a thousand people auditioning for the parts, 16-year-old model Erena Mizusawa and 20-year-old D-BOYS actor Koji Seto were chosen to star in the series.

Originally based on a mobile phone novel, the story was turned into a hit movie last year starring Yui Aragaki and Haruma Miura. When it was announced in May that the drama version would have a different cast, producers were said to be looking for a pair with relatively little acting experience.

Mizusawa, a model for the magazine SEVENTEEN, just made her acting debut in BS-i's "Koisuru Nichiyoubi" drama program this past March. On the other hand, Seto has been with the acting troupe D-BOYS for about two and half years, and is currently gaining plenty of exposure as the hero of "Kamen Rider Kiva."

"Koizora" starts on August 2, airing Saturday nights around 8:00pm.
