Please read the description of pool #1791 and you'll see that this really isn't what the pool is for. If the mere presence of a company's branding counts as a "crossover", then literally any post where a Japanese character consumes a Western product is a candidate for inclusion in the pool. When you use this pool for fast-food franchises, save it for the ones where the company's mascot is actually present, like post #2196669.
