Aoi Blink EP18 - Will It Bloom?: The Flower of Dark in Emerald Forest

Kakeru and the others come to Emerald Town in search of his father Haruhiko, who had been sent down the dark river. This town is filled with flowers. "If you look for the seeds of the flower of darkness, you will reach the dark river," says a girl named Fula, who becomes friends with Kakeru. So they head for Emerald Forest.
