Mametchi continues to research the Tama Hearts and Kizunatchi's connection to them, eventually learning about Hatokamitchi, the god of Tama Hearts. The Tama-friends eventually visit him at Ha Island and he encourages them to collect more Tama Hearts so the ancient heart stored in the island could be summoned and used to bring back all the missing Tama Hearts on Tamagotchi Planet.
The gang all tries to have faith in Kizunatchi as she attempts to cure the entire planet and its inhabitants of the egg curse.
