A modern corporation's work opening doors to other dimensions has had the unintended consequence of making our world vulnerable to demons from beyond. In Persona, a role-playing game set in the contemporary age of cities and AK-47s rather than one of castles and broadswords, a group of teenagers is working to stop the havoc brought by the invading demons. Your characters gain experience for fighting, but they also gain by not fighting; talking your way out of battle adds to your ability to use magic, which adds to your assets when the gloves really have to come off.
