The theatrical frog animation movie is the latest in the franchise based on the hugely popular Sergeant Keroro manga series by Mine Yoshizaki with a television series directed by Junichi Sato.
In Sergeant Keroro the Movie 2, the alien frog and his corps are faced with the mission to rescue princess Natsumi and save the world, but their battlefield has moved from space to the deep blue ocean.
The film also has a 3D CGI segment dubbed the 'Keroro Special' which will uncover the secret of Keroro's childhood, and the biggest mystery of the animation - why he is in yellow.
'Rose previously bought the Sergeant Keroro the Movie episode 1,' says Nobuhiko
Kurosu, general manager at Kadokawa Holdings China. 'We've been having a lot of interest from other buyers, but Rose Media was very eager to have the film.'
Kurosu did the deal with Rose Media & Entertainment vice president Oraphan Monphichit.
The film opened in Japanese theaters March 17 and took in $1m over the weekend. Kadokawa expects the $3m-budget film to rake in over $10m by the end of its run.
