Isshin Sumeragi

Isshin Sumeragi is a character from Code Geass: Shikkoku no Renya and a member of the Sumeragi clan. He is the leader of a mercenary band from Kyōto who were hired by the Portugese Jesuits to raid the village and find Carla. He seems to scar his own body when he kills a worthy opponent to him. He also seems to have a tough body, since he survived from a sakuradite explosion. He is killed by Renya, following the failure of his contract.

Three brothers
They are triplets who seems to be the second in command of the mercenary band. Each one of them uses a different weapon. One has a katana/long sword, another uses a samurai bow, while another uses a chain with a spear-like blade at its tip. They are killed by Renya and Andreas.
