Beast Hunters

Qualifications
Over 18 years old (Sometimes minors above 16 are accepted by schools if they show promise),

Payment & reimbursement
Hunters may be hired personally for specific jobs, but they generally spend most of their time eliminating Monsters. It's sort of like volunteer work.

Purpose
Since parasitic creatures pose a threat, each in their own way, so these Hunters are trained to keep them at manageable numbers.

Social Status
Being a Hunter is generally a highly respected position, seeing as it's so dangerous. Monsters are very intelligent, and are not afraid to kill. They don't hesitate.

Dangers & Hazards
Being a monster hunter is an extremely dangerous profession, seeing as you're hunting creatures that could not only kill you, but some could get you to kill yourself.
