Hidden in the forests of the mist, the scroll house is guarded by two-man ANBU team Yin & Yang. The scroll house is guarded by a special barrier created by the two-man team to reflect the forest around it, making it utterly invisible. Only one satsubatsu of the mist, and the Mizukage himself know where the scroll house is, and therefore they are the only ones able to get to it. It is them who can only access the scroll house.
