Houpriyusu

 is a trainee unit of Houkago Princess. The members here are candidates and apprentices and are working on training so that they may eventually debut with the group one day.

Candidate-members perform more regularly with the group and sometimes have a spot in one of the singles. The apprentice members perform mainly as backup dancers.

They were created on February 18, 2015.
