Kosetsu 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 by stabbing his sword through his own knightmare trying to destroy Rolo's Vincent in the battle of Babel Tower to allow Zero (as well as Kallen Kozuki, C.C. and others) to escape. According to C.C. and Kallen, Urabe has no sense of taste.

First Season
Urabe first appears with Kyoshiro Tohdoh and the Four Holy Swords to defend the Japan Liberation Front from the Britannian Army. He is piloting a Burai Kai, an upgraded version of the Burai. While defending, Zero retreats leaving Tohdoh and the Four Holy Swords to fend by themselves. As a result, they abandoned their knightmares and escape. He is later seen with Tohdoh and the others for a meeting, but are discovered and Tohdoh sacrifices himself and becomes captured to let Chiba, Urabe, Asahina and Senba escape. Then, the Four Holy Swords turn to the Order of the Black Knights for help to rescue Tohdoh.

Urabe and the Four Holy Swords are given the Gekka to pilot by Rakshata. They break into the prison and rescue Tohdoh. Then, Urabe fights against Suzaku with Tohdoh and the others. Tohdoh and the Four Holy Swords knightmares take damage due to the Lancelot's Harken Boosters. They spot reinforcements and Tohdoh gives the command to release the chaffsmoke and escape.

He is seen later on after Euphemia massacres the Japanese due to Lelouch's Geass and follows under Tohdoh during the assault of the Toyko Settlement. He is actually not seen at all during the assault, but is mentioned by Asahina when Tohdoh asked him of his whereabouts and said that he was moving on to the energy filler repository.

Second Season
After the failed rebellion, Urabe was only one of the few who managed to escape. During this time, Urabe found out Zero's real identity and set up a plan to get him back. So, they hide the remaining Black Knights in a commercial blimp and land on top of Babel Tower and initiate their plan by releasing smoke. After Lelouch regains his memories and becomes Zero once more, Urabe and Kallen meet up with Zero and start to destroy the Britannian forces. After most of the Britannian forces inside Babel Tower were eliminated, Rolo came in piloting the Vincent and attacks the Black Knights. Urabe and Kallen protect Zero from Rolo and start to battle each other. However, with Rolo's Geass, it makes Urabe, Kallen and Zero see him going at a fast speed. Zero is almost struck by Rolo, but is intervened by Urabe. Urabe tells Zero that he doesn't care what his background is or if he's just a student and to help the Japanese people. Then, he uses his Gekka's Revolving Blade Sword (Katen Yaibatou) and stabs it through his Gekka and the Vincent and dies from his Gekka's explosion.

Quotes

 * "Zero, I don't care if you're really a student or what your background is and I know you meant it when you said that we're not expendable. I know that every fighter we got counts. Kozuki, protect Zero, he's our last hope and hope is what our people need."
 * "Zero, save Japan, help our people to lift their heads again and fight!"
 * "The Four Holy Swords have proven our worth."
