So from what I see then is:
Roof - Kuro, Paneru, Megumi, Reiko, Aki and Kenny
4th floor - Empty
3rd floor - Utaho, Kurisa, Shoske and Akane
2nd floor - Zombies
1st floor - Empty or Mi and Yukito
Outside - Hatake's character

If this is wrong or I've missed a character, can you lot add where your characters are currently just so that we know where everyone's at f(^_^') Just to avoid confusion
