Tetsutarou Doi

Tetsutarou Doi (土井哲太郎, Doi Tetsutarō) is a member of the ultra-nationalist organization of Tokonosu under Souichiro Takagi.

About
Little is known about Tetsutarou except that he is a friend of Souichiro as well as a member of his ultra-nationalist party.

Appearance
Exactly how Tetsutarou looked before he became one of "Them" is unknown. However, it can be seen that he had black hair and wore the standard uniform of Souichiro and his men. As one of "Them," his left eye is usually closed, and he has the typical grayish skin and gaping mouth.

History
Tetsutarou has been good friends with Souichiro for 25 years. He has served the man alongside Yoshioka and other retainers. Some times later, he saved a junior officer from "Them. But got bitten and became as one the "Them".

Personality
Tetsutarou is described by Souichiro as a noble man after he sacrificed himself to save a junior officer from Them.

Plot
When Souichiro and his men arrive at the Takagi house, Tetsutarou is brought in a cage carried by a forklift to a platform that Souichiro is standing on. The people sheltering at the Takagi house gather around the platform, and he tells them Tetsutarou's name and that they have been friends for the past 25 years. He explains to them that Tetsutarou was bitten while attempting to rescue a junior officer, and his self-sacrifice was the most noble thing a person could hope to do. He then tells them that Tetsutarou is no longer human and his life ended when he became one of "Them." He opens the cage, and, when Tetsutarou charges out, Souichiro cuts his head off. The people are horrified when they see this. Souichiro says farewell to Tetsutarou, and then he stomps on the head and crushes it. (In the anime, this scene is omitted, and the head simply rolls into a fountain.) Souichiro uses this demonstration to try to make the people see what is really going on in the world.
