In 'The Gurdian's Challenge!', The next day, Lillie gave a recipe to Mallow for some Pokémon food. Mallow assured Lillie that one day she will be able to touch any Pokemon. In 'Alola to New Adventure!', Lillie denied that she can't touch Pokemon, claiming she only touched Pokémon once she knew it was safe to do so. Lillie and Mallow (along with their classmates) are a part of Professor Kukui's class at the Pokemon School, and are also members of the Ultra Guardians: Mallow is the Green Ultra Guardian and Lillie is the Pink Ultra Guardian. And Lillie, along with the others, have always been supportive of Mallow when she is working at her family's restaurant or trying out a new dish idea. Mallow and the others were so proud of her bravery. At the end of the episode, Lillie fully conquered her fear and can touch any Pokemon. When Lillie temporarily went back to square one and couldn't touch any Pokemon, including her own partner Pokémon, Snowy, after remembering Type: Null in a memory from the past of the incident that caused Lillie to develop her fear of touching Pokemon, Mallow and the others felt bad for Lillie and encouraged her to never give up and keep trying. Even though everyone was supportive in Lillie fighting her fear, it was shown multiple times throughout this ordeal that Mallow cared the most. Mallow, and the rest of the gang, have always been supportive for Lillie when she had her fear of touching Pokemon and wanted to conquer it, and had made great progress.

They share a notably strong bond compared to any other relationships in the show. Lillie and Mallow are close friends, and classmates at the Pokémon School.
