1) As it was something unusual in a manga to see many people arriving at the same time to save the situation? But if you want a more logical explanation, just think that all these people were around town and just followed the sperm-people and the lights of the battle.
2) First, they had plenty of time to panic and be depressed about the situation during the time we don't see them. Second, they all used a stick and thus know about magic and strange stuffs happening, so they are more prompt to understand the situation than any other lambda human being.
I can't understand all these cristism and sarcasm in the comments. Yes, there are many unexpected plot twists, and this is really cool, because it's REALLY unexpected. But not unexpected in a stupid way, because the author seems to have really thought of his story beforehand. He even linked his two mangas. I really enjoy reading this manga and be surprised
