Warriors are physical battlers who use weapons like axes and swords to take on enemies. Most males in the Netherworld can become Warriors, though one must make a pact with the God of War Grandell to take on the title. Warriors wear light armor, but can harden their bodies instantly as a defensive measure. They are aggressive wandering soldiers with a low capacity for friendship, but respect those they deem worthy.
Warriors are the generic physical attack class, who are easily trained to use a sword or axe.
