There are certain things that nobody wants to roleplay, and that is understandable. For those people who no one wants to be, they shall be NPC (Non-Player-Characters). If you play RPGs, this term is familiar. Anyways, good roleplayers know how to control real generic characters (Such as crowds in public places, animals, etc.) in order to add to their RP. With NPCs that are gonna show up more frequently, I will give them profiles. In villages, this will usually be the teacher in the academy. There will also be various ninja who teach specific jutsu. These will usually clan techniques. Since there is a bit of screening for you to join, I'm trusting that you can all use the NPC's profile and RP them fairly.
