Glass Mask(ガラスの仮面Garasu no Kamen) is a shōjo manga series written and illustrated by Suzue Miuchi, serialised in Hana to Yume from January 1976, and collected in 44 tankōbon volumes as of August 30, 2009. The story has also been adapted into anime and a live action television series. As of 2006, the collected volumes had 50 million copies in Japan, making it the second best-selling shōjo manga ever. The title refers poetically to the mask of faces that actors wear - while expressing emotions that are not their own, the mask they wear (their acting) is as fragile as glass. If the actors are distracted, their mask will "break" and show on stage the actors' true feelings.
