This wall is an invention of the Cultural Institute, created using liquid crystal particles. According to the plan, the particles are capable of completely recreating the texture of any material, which can be used to hide a valuable object. Chihare Amano claims that the idea of creating this scientific ninja tool belongs to her.
Such a wall was installed in Tami's candy store, and was also previously located in Chihare's laboratory, but was destroyed along with the laboratory.
