Testament

Testament is a machine used to install information into a human's brain. Notably used for the Sisters Project under the supervision of biopsychologist, Nunotaba Shinobu.

Appearance
The machine appears in a form of a capsule, large enough for an ordinary middle school girl to fit in, though there are probably other variations of size depending on the person. The seal for the machine is transparent, and observers from the outside can fully view the recipient. Inside, the subject wears a helmet which is connected to tubes and wires, though another Testament machine showed the helmet covering the eyes and ears of a Misaka clone which probably produces the same effect. Outside the capsule, several tubes and wires are connected to the machine and probably leads to the bank where the information to be installed is stored.

Use and Operation
The subject lies down inside the apparatus, here, the helmet is inserted unto the subject's head. By sending out electrical signals into the brain, the machine can input a large amount of information in a short period of time and affects all five senses of the body. Using the machine, information such as speech, logic, motor functions as well as the personality and emotionsof the subject can be installed.
