This roleplay seems to expand constantly, so I try to diversify the resources within it to adjust. Regardless, PM me with any questions you may have. The setting isn't too complex. The world has only been free of Sai for about a year and half, so your character, as a Chuunin, was most likely involved in the resistance, but wasn't quite capable enough for the Hokage to deem a Jounin or Special Jounin.
