Hunters & Hunters - S0.E6

Belldandy, Keiichi, Urd and Skuld are trying to pass the time on a hot summer evening when they are suddenly visited by the two goddesses-in-training Eir and Saga. It turns out that every year the Goddess Assistance Agency hosts a shell gathering tournament and they've come to challenge the legendary champion Belldandy for a shortcut to fame. Since Keiichi is a seasoned shell gatherer himself, he confidently joins the goddesses in the tournament. But when it turns out that shell gathering is done a little differently by goddesses than he is accustomed with, he'll need to adapt quickly in order to help Belldandy keep her title and prevent even greater consequences in the process.
