The tenth season of Huyao Xiao Hongniang.

Mini web anime streamed online leading up to the Mars Red TV anime premiere.

Hana, Hinata, Noa, Koyori, and Kanon are always good friends. Today, they are having a friendly sweets party at home with Miyako's homemade sweets! The flower-shaped cookies look just like the hair ornaments worn by Hana. The hair ornament was a precious treasure that Hana received from her grandmother when she was little, and everyone was intrigued by the story. And as "practice for the school trip," they decide to go visit Hana's grandmother's house...! The "first" outing for everyone is about to begin.

The anime centers on Manatsu, who moves from her small island birthplace to a city and starts middle school. On the day she moves she meets a mermaid girl named Laura who is looking for the "legendary warriors," the Precures. Laura's hometown, the mermaid country of Grand Ocean, has been attacked by the "procrastination witch," who has stolen the country's "motivation power." (Source: ANN)
