Hebitani Tsuguo
蛇谷 次雄
The leader of Big Spider, he is behind the attacks perpetuated on espers and won't hesitate to kill to maintain his iron grasp over the gang. Though he initially claims to be Wataru Kurozuma, the former leader of Big Spider, this ruse is exposed (and Big Spider dissolved) when the real Kurozuma returns.
