Also, I had a random idea involving N-Forza in Ijiyatsu.. While I guess there wouldn't be any room for a 'shopkeeper' type person, he could be like the Rinnosuke to our CPMC Gensokyo. :V
I randomly imagined an in-game Extras shop that N-Forza would be the staff of, or something like that. Of course, if there are any spinoff games..
