电影Tropical-Rouge！光之美少女 雪之公主与奇迹的戒指！

This is the 30th overall film in the "PreCure" anime theatrical series and the movie adaptation of the 18th series, "Tropical-Rouge! PreCure," which aired from February 2021 with a "sea" x "cosmetics" motif. The PreCures from the 7th series, "Heartcatch PreCure!," which aired 10-11 years prior, also appear, resulting in a collaboration between two generations of PreCures. Invited to the celebration ceremony for Sharon, the new queen of the snow kingdom Shantia, Manatsu Natsuumi and the others arrive in a sparkling, radiant world of snow. Laura, who aims to become the queen of the mermaid kingdom, becomes friends with Sharon and receives a beautiful ring as a gift. The two then make a certain promise, but the appearance of a mysterious monster traps everyone in the snow kingdom. As Manatsu and the others find themselves in a pinch, the "Heartcatch PreCure!" team rushes to their aid this time. Encouraged by this, with everyone's feelings overlapping, Laura's ring transforms into the "Snow Heart Ring," but... Marika Matsumoto guest stars as Sharon, the Snow Queen.
