In order to hold back the advancing Imperial Army at the border, Grand Master Harold takes the royal flagship to the front lines. Joshua throws himself into his first combat sortie in order to protect Yuki's smile.
It's bad for your health to 
stay up this late, Princess.
من المضرّ لصحّتكِ أن تسهري حتّى
هذا الوقت المتأخّر يا أميرة
Es ist ungesund, bis spät in die
Nacht aufzubleiben, werte Prinzessin.
Desvelarte es malo
para la salud, princesa.
Trasnochar es malo
para la salud, princesa.
Veiller tard est mauvais pour la santé,
dame Yûki.
Non fa bene alla sua salute
stare sveglia così a lungo, principessa.
Não faz bem para a saúde ficar
acordada até tarde, princesa.
Вредно не спать ночью, принцесса.
