Lulu (Japanese: ルル Lulu) is a character of the day in Three Sides to Every Story!.
Lulu was searching for her Marill who was wondering where it ran off to. She introduced herself to Ash and his friends and then explained to them that she lives on a Berry farm with her parents where they harvest many Berries, including the rare Lum Berry. Lulu's parents were out and wouldn't come back home for another 2 or 3 days. Lulu decided to have the group stay for the night so that she wouldn't feel lonely while her parents were out.
During the nighttime, Lulu discovered her Marill was missing along with Piplup and Elekid. She and the group go searching for them and find them by a grassy-area battling Team Rocket. Back in the orchard, Lulu gave Ash a box of Berries before the group headed over to Twinleaf Town.
