HPC49

'Minna no kokoro wo hitotsu ni! Watashi wa saikyou no Pretty Cure!!' (lit. Everyone's Hearts are One! I'm the Strongest Pretty Cure!!) is the 49th and final episode for the season Heartcatch Pretty Cure!, the seventh season in the Pretty Cure franchise, including the 341st episode of the Pretty Cure all series.

Summary
Dune has withstood the Heartcatch Orchestra and reveals his final true form. The Cures, together with Kaoruko and Coupe, escape from the collapsing fortress, and resolve to confront Dune one more time in order to calm his raging heart. The Cures and the three fairies combine their feelings into one, and transform into a single Earth-sized Pretty Cure, Infinity Silhouette. Dune attempts to attack her, but a strong invisible forcefield prevents him from even touching her. Infinity Silhouette proceeds to perform Straight Punch and lands her fist on Dune's heart, with the explosive impact delayed by a few seconds, and the earth is restored to its original, natural state.

The girls continue their normal daily school lives with fresh, new changes brought in; Itsuki wearing the normal girls' uniform and having slightly longer hair; her older brother having recovered from his illness, and being able to continue his martial arts; Kumojaki, now known as Kumamoto, wishing to train with the Myoudouins; and the other two villains, Sasorina and Cobraja whose hearts were purified, now starting anew in their lives. The final scene shows Tsubomi's new little sister, admiring the group picture of the four Cures and holding Tsubomi's Heart Perfume.
