AT FIELD

AT Field is the acronym for Absolute Terror Field. The AT Field is a special kind of force field that prevents any projectile or close range weapon to hit the target. In later episodes, particularly in episode 24, Kaoru says that the AT Field is actually the soul. It can never be penetrated by anybody. Everyone has an AT Field.

Developing the same AT Field in the same wavelength can only neutralize the enemy's AT Fields. Although humans have tried to create artificial means to generate the AT field, attempts were unsuccessful.
