all the male hashira from demon slayers in maze runner, but they arent the only people living in the glades.. the Grievers. the grievers resemble gigantic spiders with cybernetic limbs and only come out at night, when the maze closes off, keeping the people safe. Their sting causes symptoms like being uncontrollably aggressive, dark veins being visible. (they live in the glades and try to escape, when/if they do they have to build camp and fight off cranks.)
