Claw

Claw is a criminal organisation composed entirely of Espers. They recruit Espers to strengthen themselves and plan to overthrow the world government. The organisation was founded and is led by Touichirou Suzuki.

Scar
"Scar" is a special cadre of the organisation, composed of particularly powerful Espers. When a member of Claw defies and/or challenges the boss, a wound is placed on them; this mark is representative of the boss acknowledging the recipient's skills and thus they become a member of "Scar".
