Tamagotchi Angel (1997)

On the Tamagotchi Planet, floating in the sky is the Tenshitchi Capital, home of the Angels, the spirits of Tamagotchi characters that have died. Angels water the clouds to provide rain across the Planet, grow their angelic powers through prayer, and help and guide the living Tamagotchi in small ways. On the Tamagotchi Angel, many Angels returned to The Earth to spend more time with their human caretakers, and to thank them for letting them live good lives. However, they cannot be away from the Tenshitchi Capital for very long, and must eventually return. The user is tasked with raising their Angel, training them to do good deeds while keeping them from becoming the evil Deviltchi.
