Isn't that exactly what you're doing right now?
NOTHING NOTHING NOTHING IS CONFIRMED.
DO NOT STATE SPECULATION AS A FACT.
Can you guys maybe tell what my pet peeve is?
Yes, with the Sky Arrow Bridge resembling Nanpu? bridge, Shanghai has a lot going for it, and yes, I do personally think that it has a high chance of hosting the Isshu region. However, it may not. It. is. not. con. firmed. Honestly, when is it going to get into your heads that you are not correct if the information hasn't been released?
Also, the pokemon that live in the region don't support its origins at all. Are beavers, giraffes, elephants, scorpions, and armadillos native to Japan? No, they aren't. We have a bald eagle in Isshu. For those who say that doesn't mean it's New York, well, your pigeon doesn't mean it's Shanghai. Again, say it with me, this is all speculation, and not fact. It is not fact. Don't treat it like fact. Don't state it as fact.
Besides, if that blue bird is a Mamepoto evolution, to me that seems like the perfect link between Mamepoto and Woogoru.
