This Four Giants were the Bosses of The Abukuma Territory (a place near Kyoto town). One day Aoshi was walking around Abukuma through the way to Kyoto to meet Makoto Shishio. Then these four bald giants stood in front of Aoshi and challenged him to fight or die. When they began to attack, Aoshi removed the sword case and he uncovered his two Kodachis, then the four giants were surprised and in that moment Aoshi finished them quickly.
