In Jisatsu Circle (Aka Suicide Club) by Furuya Usamaru, this name was a bit of an anomally. With each wave of the club, the sole survivor would become the new leader of the club, shed their given name and surname and would be known simply as "Mitsuko". It's ironic that in such a dark series, the leader of the group would be called "Light Child".
Mitsuko was the main character in Little Sister and The Heavenword Path by Kara Dalkey. These two books are about life in imperial Japan. Mitsuko's nickname was Mitsu.
