Koutarou and Harumi end up as the leads in the play. During rehearsals Theia notices that Koutarou is a surprisingly good fit for the role of the Blue Knight, while Kiriha wonders about similarities between the Blue Knight and a person from her past. Theia's rival for the throne, Princess Clan, appears and tries to kill Theia, but Koutarou somehow is able to summon power in his sword replica and repulse Clan and drive her off with the help of Kiriha and - unnoticed, of course - Yurika. Theia orders Koutarou to undergo knight training - and knights him while he is sleeping.
