Type: Raiton Ninjutsu
This is a mostly non-combat Raiton ninjutsu. To start the ninjutsu the ninja does the needed hand seals and then sticks three kunai in a triangle around the other ninja. No one can be in the way of the triangle. After the kunai are placed electrical walls rise up and connect the three Kunai together. The walls are 10 feet high and can not be broken from the inside except by a B ranked or higher Fuuton jutsu. The walls can be broken from the outside by a C ranked or higher technique that isn't a Taijutsu. If anyone tries to touch the walls they will be electrocuted badly but not badly enough to kill them. After the walls are formed, a ceiling closes it off.
