When Theia’s Blue Knight detects a strange anomaly near Earth, it looks like Koutarou and the others have a new kind of invader on their hands. Another princess from Forthorthe has come to sabotage Theia’s trial, but no one seems to be able to find her! The threat lingers as they get involved with the drama club and agree to help put on a very special play for the upcoming cultural festival. And just how long can Yurika keep a you-know-what in room 106 a secret from Ruth?
