Now, imagine this doll house as our school.

It's pretty simple, actually. We strike at the center.

The computer system. It runs everything from the grading system to the air condition.

We knock down the power, and thus the alarm, and then we go and clear everything.

The only problem is ... it's difficult to enter ... and that's why we need a third party.

An innocent pawn that helps us.

We just need one...

Third party?
