The project’s premise follows Kōta Hasegawa, a high school boy who loves the yellow Pom Pom Purin dog.
The overall project launched in January 2016, and Sanrio launched a merchandise line for the project in April 2016.
An official Twitter account for a Sanrio Boys stage play adaptation opened in March and announced the play’s cast and winter 2018 premiere on Thursday.
Together, Kōta, Yū, Shunsuke Yoshino, Ryō Nishimiya, and Seiichiro Minamoto learn to accept their love of the characters instead of feeling embarrassed.
