Horpun is the seventh Heartiel in Futari wa Pretty Cure Max Heart. Heartiels are fragmented embodiments of the Queen of Light's will, dispersed following her battle with the Evil King. Twelve Heartiels exist, each symbolizing a distinct virtue essential to the Queen. Horpun manifests during a specific event where the main protagonists exhibit strong positive emotions and unwavering hope while facing a challenge, occurring after they successfully protect an ally and share lighthearted laughter. Like all Heartiels, Horpun's function is to be collected and returned to the Queen Chairect, the item representing the Queen's heart. Gathering all twelve Heartiels is necessary for the Queen of Light's full restoration.
