Fyodor Dostoyevsky
Demon, フョードル・ドストエフスキー
Head of Underground Organization "Rats in the House of the Dead."
Spoilers:
His ability has yet to be described. It is hinted to be something that is able to kill someone with one touch as shown in chapter 42. This ability is not restricted to skin-to-skin contact, as when he was grabbed by a government agent who had gloves, the agent was killed by Fyodors ability.
