"Swordmanship is cool, isn't it. Let's set up an awesome school all by ourselves!"
The Kikoukenjutsu Sword School (気功剣術, Kikōkenjutsu; lit. "Energy Control Fencing") is a martial arts academy reported to have been created and instructed by Trunks and Goten after the events of the original Dragon Ball manga. The school debuts in the computer game Dragon Ball Online, along with Krillin's New Turtle School and Tien Shinhan's New Crane School.
After the release of Gohan's book, "Groundbreaking Science", which informed the general public of advanced martial arts, the people of Earth took great interest in fighting. Some specifically gained interest in the theory of channeling ki energy through swords to increase the speed and power of strikes because of the book's article "Katchin Can Be Cut!". This article reveals that the dense material Katchin can be cut, which greatly intrigue Trunks and Goten. "Swordmanship is cool, isn't it. Let's set up an awesome school all by ourselves!", the two become enthralled by this motivation. Via intense training, the two are able to develop their natural potential and, as adults, create the Kikoukenjutsu Sword School to educate the planet's new generation of warriors.
In Age 820, remnants of Frieza's Galactic Frieza Army attack Earth and the Kikoukenjutsu Sword School is reported to play a major role in their defeat; being the only major fighting school established until a year later when Krillin and Tien's schools are founded. The Kikoukenjutsu Sword School still exists as of Age 1000 and is one of the most notable schools on the planet.
