The user guide for the Yasashii recounts the tale of Tamagotchi Planet getting drunk, causing the Tamagotchis to escape to Earth. Almost two years later, it's time for the Tamagotchis to begin their journey back home. Professor Banzo, the creator of the original Tamagotchi device that allowed them to live, still wished to improve the living conditions for the Tamagotchis. Alongside Mikachu, he eventually developed the Yasashii, a more spacious and comfortable home designed to make caring for Tamagotchis easier. The Yasashii Tamagotchis, or "YasaTamagotchis," were born and raised on Earth. As a result, they only know about Tamagotchi Planet through the stories shared by older Tamagotchis who once lived there. The YasaTamagotchis are eager to visit their ancestral home for the very first time.
