No Ones POV
The group of 15 were on the staircase, that is connected to the first-years hallway and second-years hallway. But something is in there way.... The hole first-years hallway is pack with undead students from all three grades, however they're many many more undead students and teachers that have both school buildings surrounded.

The group is discussing if Saya Takagi's theory is right, that the undead can't see anything in front of them, and the rest of their senses are dead, besides being able to hear.

Toshimi Niki looked through her bag, and she pulled out a few emergency alarms.
"Um, hey guys," the group turn to her, "I have these emergency alarms, if you pull the cord a very loud alarm will come on. If we through it once we get outside, the noise will bring all of the undead students and teachers all over the campus into one place." All the survivors gave her a scared look, and told her to be careful with those, because one wrong move they could have the whole undead school surround them in minutes.

So Niki, put them on her bag to keep the string from getting pulled while they are on the the move.

In order to escape from their school in one peice, Komuro walked down the stairs as quietly as he can as not to draw any attention to himself, once he was standing in the middle of the undead students, he looked down the hall were the classrooms are. And outside classroom 1-A the body of a female student lays on the floor, on her side, cover in blood and one of her shoes is next to Komuro's foot.

'Poor girl, she didn't stand a chance.' Komuro bends down to pick up the bloody shoe, when the undead students just walked by him, one was in front of him and just walked around him. And the moment he through it at a set of lockers by classroom 1-B, the undead students and the body on the floor started moving to the sound.

Komuro and Busujima changed out of their school shoes, and put on their regular shoes, and they hold the doors open so everyone else can changed their shoes and ran outside.

It was going well, until one of the survivors weapon accidentally hits the staircase railings making a sound so loud that the undead students in the hallway and outside the school heard it and they all turn their heads to the noise to find their next meal.
