I was dressed up a bit, in pressed black slacks, a black tailored dress shirt with a mandarin collar, a long black cloak hanging from my shoulders, a black walking stick, and with a small set of costume horns poking out of my temples.
Several people in the dealers area and artists galley referred to me as "The Boss" and offered me small presents. As in telling each other "Look, it's the Boss. Quick, give him a donut."
To which anime or manga were they referring?
