[Yuno Gasai & Yukiteru Amano (Group A) - West Hall, First Floor Main Building]

"Yeah, just like a puzzle. We do need to plan things out, because if we did find this corpse recently, there's definitely someone out there to get to us," Yuno says, remembering about the corpse and how it's obvious that someone was responsible for the death. Though, Yuno smiled happily at Rikku, somewhat having a sudden idea. "You know, if we do have to put these pieces together like a puzzle, I think we only need the pieces. Besides, it doesn't hurt to have some bait to distract and buy time for me and Yukki from the killer," Yuno says towards the other girl, really wanting to get rid of this other girl due to the risks of losing Yukiteru to this girl. As for Yukiteru, he was flabbergasted to hear that comment from Yuno, even when they were in a situation where anyone could die. "Y-Yuno...I don't want anyone to be bait here," he stuttered in shock, but saw that Yuno was hugging his arm tightly.

"But it's all for you Yukki," Yuno protested innocently, still not getting the point from Yukiteru that she shouldn't hurt others just for him.

[Group A (Kurama) - Classroom 2-A, Second Floor Main Building]

Just like the newspaper said, there was no chances of leaving the room and still be alive. Sure, there was the missing parts of the floor that led to the black oblivion, but that was it. Nothing else seemed to be of notice in the classroom, most of the stuff that was there was either basic school supplies or just plain dust. The only things that were related to the whole trapping was the skeleton of the previous trapped victim and the newspaper that had the message that he couldn't leave. It was certain that the newspaper was some sort of catalyst for the trapping in the first place, and it was only a single page, there wasn't anything else he could read for anything clues other than that eerie message. Even if there wasn't anything else to be read on the newspaper, maybe there was something he could do with it still...

[Group B (Dr. McNinja & Grant Harrison) - East Hall near girl's bathroom, Third Floor Main Building]

Regardless of what sudden conflict had currently taken place, they would still hear the distorted crying coming from the girl's bathroom.
