Momo is the princess of Fenarinarsa, a land of dreams that is getting further and further from Earth. She is sent to help the Earth regain faith in its dreams.

She's ready and willing to help anyone she can in order to make their dream come true, no matter what happens.

On the first day her family moved to their new house, 5-year-old Ami-chan made friends with three talking animals who came out of a door in her bedroom floor, which she finds out leads to Animal Yokocho, another world. The three are Issa, an overly innocent, soft-spoken panda, Kenta, a highly strung, red-scarf-loving bear who puts on an almost constant tough-guy act, and Iyo, a rabbit who usually holds her own well-being and enjoyment over the happiness (and safety) of her friends. Even at only 5 years old, Ami-chan is easily the most rational of the group, and she's a little wary at first, but she eventually comes around and starts spending her free time with them. A typical day involves Ami-chan and the three doing different things to pass the time, often playing a seemingly innocent game, but in AniYoko style. Unfortunately for Ami-chan, the AniYoko version usually turns out to be drastically different, much less logical, and usually more dangerous than the ordinary version. (Source: ANN)
