Summary So Far:
After the sudden assault by the Theater Troupe Actor, Itsuki and Nina were able to repel the attack within the school. Yet, strangely, there was no trace of students or teachers in sight, and the only clue they had was a message instructing them to head to the rooftop.
"… 'Come to the rooftop,'" Nina translated the English phrase written on the blackboard.
Her translation was incredibly helpful, especially since I was clueless about the language. Someday, I should learn some translation magic myself, I thought absentmindedly as I processed the meaning.
It was obvious that this message was meant for us. There was no one else around to read it, after all.
But just because the message told us to go to the rooftop didn't mean we'd willingly walk into whatever trap might be waiting for us up there. Monsters could be lying in wait; it was practically guaranteed.
"Itsuki, what should we do?" Nina asked.
