Four Holy Swords

The Four Holy Swords are an Elite group of soldiers who serve Tohdoh. Initially, they are a part of The JLF, but once Kyoshiro Tohdoh is freed from execution, they join the Black Knights. By the end of the series, only Chiba survives.

Shōgo Asahina
Asahina Shōgo is a male member of the Four Holy Swords. He wears glasses and has a distinctive scar down the right side of his face. Like Chiba, he develops a distrust for Zero following the Black Rebellion, questioning his tendency to keep secrets and bring on new members such as Rolo and Jeremiah with no discussion. He is the leader of the first squadron of the Black Knights. After the formation of the United Federation of Nations and the Black Knights' appointment as its unified army, Shōgo is made the 1st Division Captain. During the second battle of Tokyo, he is killed in the blast from Nina's F.L.E.I.J.A. bomb whilst trying to pursue Rolo, but not before transmitting information about Zero's massacre of the Geass Directorate(which in turn came from the Squad Zero lieutenant who participated in it) to prove Zero can't be trusted.

Nagisa Chiba
Chiba Nagisa, 29 years old (30 at R2), is the sole female member of the Four Holy Swords, she also seems to hold a crush on Tohdoh, also noticed by her comrade, Asahina. A year after the Black Rebellion, she harbors animosity towards Zero for abandoning them. She survives the final battle but is captured along with all the other Black Knights for a public execution. She is released when Lelouch is killed and is seen together with Tohdoh in traditional Japanese attire in a photo of Kaname Ohgi's wedding.

Ryōga Senba
Senba Ryoga was the oldest member of the Four Holy Swords (even older than Tohdoh), and appears to be its leader. He is killed by Gino during an assault on a Britannian aerial transport. His last words were that he wanted to see Japan being liberated.

Kōsetsu Urabe
Urabe Kosetsu, is a male member of the Four Holy Swords with blue hair, he appears to trust in Zero more than his teammates. He is one of the few top officers of the Black Knights not captured by Britannia after the Black Rebellion, as well as the first member to discover Zero's identity. He is killed by sacrificing himself against Rolo's Vincent in the battle of Babel Tower to allow Zero (as well as Kallen, C.C. and others) to escape.
