Low-Frequency Vibration Therapy Equipment

Low-frequency vibration therapy equipment (低周波振動治療器) is a device that is designed to be placed on a person's shoulders. It uses vibrations to massage and reduce the user's stress. It is given by GROUP's technical department to Musujime Awaki to aid her in her missions to counter her stress and can be assumed to have been constructed by themselves.

Principles
Electrodes are stuck onto the shoulders and back of the user and it looks like a compress. It is a machine that sends electric currents into the body. The machine measured the disturbances in the user's brainwaves and creates the most effective pulse pattern based on it.

Drawbacks
The stronger the stress involved the greater the pulse sent out by the device. A sufficient amount of stress can force the device to send out enough electric current to cause pain and discomfort to the user.

Awaki removes the device from her neck against her battle with Teshio Megumi, deeming that she cannot protect anyone in her current state. However, because of the anti-esper technology, specifically the AIM Jammer, used in the facility where they are fighting, she accidentally teleports her leg into the ground, but manages to overcome her trauma, and defeats her.
