We might need a slogan for this movement. Like #sixinstallmentsandananime
In all seriousness, tho, is there anyone a frequenter in Japanese fandom? They are quite active in making small fan events, like the Twitter characters rank voting or an installment anniversary event. We can set up something similar, maybe favorite characters/scene/anything ranking similar to chara ranking in Marugoto! book, or fanwork events like Mark of Stars and 108fanarts in LJ.
I mean, we have been spread over different sites until recently. Tbh, I'd like to have fun and getting know other fans first before going straight for big goals. Just like Suikoden itself -- the army exists not only because of having 108 characters, but 108 characters interacting with each other.
