Heartful Echo (ハートフルエコー Hātofuru Ekō?) is a purification attack used by Cure Echo in Pretty Cure All Stars New Stage 3: Eien no Tomodachi. It is shown to be quite powerful. She used it only once.
First, she summons a small shining ball from her bow. It lies between her hands and she says the incantation. A sparkling spiral line comes from the ball and covers Cure Echo. She turns around and then shoots it to the target. The dark sky is purified and becomes normal.
