The girl, who has lost her memory, has a pendant that reveals her name to be Yuriko...

This work was serialized in "Shojo Book" (January-September 1963 issue, published by Shueisha).
This is the first e-book edition reproducing the extant two-color version!　

Also included, " Good Morning Meeko" is the mangaka's own remake of "The Milkman of Chiko,"
which was published in the 1956 summer special issue of "Shojo Book".
Both of these works have an appealing storyline that cannot be strictly categorized under the "Shojo Manga" category.
