Jo was out patrolling, a habit she had gotten into since all of the weird shit started happening. There were too many creatures attacking innocent people and she just couldn't allow that to happen without consequences.
Even almost dying and being healed didn't stop her from being a hunter.
When she heard a scream she didn't think, just took off running in the direction the scream had come from. When her eyes took in the scene of the girl being attacked by a huge wolf -- and she just knew it wasn't an ordinary wolf -- she let out a shout of rage and launched herself onto it's back, stabbing down with her knife as she did.
