Well, I'll answer these in order.....
1. Satoru is actually one of the more prestigious schools in the area, as such it's student's must look the part. Men and women both wear a custom black blazer with the symbol of the school emblazoned upon the chest. The symbol being a traditional eastern dragon coiled around the base of an olive tree. Men are also given slacks with the blazer, and women get skirts.
2. I sent her a PM a few days ago but I've yet to receive a reply. I for one would really like her to come back, after all she took my Student Council President position. Rather inconsiderate to take that and vanish really. In any case, if you want to play a third year by all means go for it, age diversity makes things a little more interesting.
3. You can play as many NPCS as you like so long as the focus remains on the primary character. Also I reserve the right to control any and all NPCs, so this secondary character would be fair game for me to use if I wanted to, like as a Social Link or something. So long as we're clear on that, then yeah go right ahead.
Well, my intention was for this RP to be slower paced and more relaxed. However I'm afraid that's what's been costing me the players. I haven't had anyone tell me they quite they just disappear. So I've decided from here on out we'll move to a faster pace to hopefully avoid losing more.
