Dokincho! Nemurin (1984 - 1985)

A 30cm doll suddenly moves! This is Nemurin, the queen of a precivilization humanity who had been sleeping for 800 million years. She and her followers, Vivian and Monroe, slept soundly until a certain day in 1984, when the kind and energetic Mako happened to awake them. Awoken from their peaceful slumber, Nemurin and her followers end up living in Mako’s home. Children sleep when they are sleepy. As she sleeps as much as she wants when she is sleepy, Nemurin is the truest form of a child. Possessing a heart as pure as that of a child, Nemurin finds herself causing plenty of trouble in a warped modern society.
