"Easy... easy... " Yuri turns back, making sure every club member is accounted for... and missing a step on the path that leads into the main building tripping and skinning her knee. (Without drawing blood, I may add) She winces and closes one eye in pain, but does not let out a peep. She checks if her equipment's still working and continues her way into the main building.

Knox and the others, by their supernatural nature or their own physical prowess manage to escape detection. There are at least 2 errant flashlights in the far corners of the school grounds, telltale signs of at least a pair of guards.

You get to the door and Yuri starts looking through the keychain trying to find the correct one in the fewest attempts possible.

Those with the sharper senses, in all likelyhood Knox and/or Amaya, notice that flashlights go out... only to be replaced by yet another sensory cue... animals.. canines, domesticated... guard dogs.

Yuri still can't find the right key... what do you do?
