The Ignis Trio is the nickname for the group consisting of Hideyoshi, Hanbei, and Kanbei. They are sometimes called Hideyoshi's Team or Hanbei's Group. The name originates from the three's homeland, Ignis, back in Ransei.
The group first appeared in season seven, coming to live in Takeru's House. They became popular for their stories at the table. The group became the ones called on for shopping, and had their own series of episodes called the Sleepover Series.
After Takeru's House broke down, the group slowly became less important. By season ten, they were minor characters.
