Tetsumou

Tetsumou (鉄網) is a young girl who is a member of BLOCK.

All of BLOCK members are not Espers but instead are all adults with proper military training, the only exception is Tetsumou who was hired by BLOCK to be a part of their security measures and is not expected to be involved in the actual operations.

She is a kind and cheerful girl who is a stark contrast with all of the serious professional soldiers that she has to deal with. Her skill is named Skill Polygraph (意見解析) of unknown level, is a telephath class skill that will allows her to verify the profile of a person as long as she holds hand with her target. The "voice" that she uses to read the profile of her target is not her regular voice but a different mechanical sounding voice, she can even read important facts that have happened to a person in the past, along with their basic information such as name, age and occupation.

During volume 15 she was requested by Saku Tatsuhiko, BLOCK's leader to verify the identity of the people present in the room before beginning the operation.... Unfortunately for her, Etzali was disguised within the people that she had to scan and he needed to figure out a way to escape that sticky situation. Etzali hid a very small quantity of plastic explosive inside the cream of a coffee coup and managed to have a random grunt touch it; as soon as the grunt held hands with Tetsumou a small explosion was created, blowing up some fingers from her right hand and causing her to faint.

Etzali regreted that result, since it caused not only damage to Tetsumou but also ended up with the grunt being executed as a traitor. Etzali also realized that if he did not used such measure, he would have been killed and no one would be able to stop BLOCK's revolt.

Saku noticed that now that Tetsumou could not function as a polygraph, she was completely useless to the team, he went even as far as calling her "a device" that needed "a replacement" and proceeded with the operations of BLOCK while he instructed some of his men to tend her. It is unknown what exactly happened to Tetsumou afterwards, but is known that Academy City's facilities can perfectly threat wounds far worse than having lost some fingers without even leaving scars.
