The female unit, long deployed out in the field, has returned to the Demon Castle to get their first taste of Princess Syalis.
I recently realized that I don't sleep
well on days I don't do anything.
أدركت أنني لا أنام جيدا في الأيام 
.التي لا أفعل فيها أي شيء
Me di cuenta de que no duermo bien
los días en que no hago nada.
J’ai compris qu’on dort mal
les jours où on s’ennuie profondément.
Mi sono resa conto che non far nulla tutto il giorno,
 mi porta a non dormire bene la notte.
Percebi recentemente que não durmo bem
quando fico sem fazer nada o dia todo.
А когда мне скучно весь день, 
я потом плохо сплю.
