Mana and Haruka were in their second room inside the building. They hastily picked up the paper. Flipped it open and whilst Mana holds the phone, waiting for Haruka to give her an answer.
"Please open the door." Haruka read. That's what was written on the paper. Nothing more.
Mana, confused by what was written on the paper, began punching in the words. But, Haruka stopped her from entering the answer 'Please open the door'. On the wall, there was a note. "The participants will be penalized by a five-second delay if they ever put or answer the wrong answer. Two wrong answers are equivalents to ten seconds delay. So on and so forth."
