Flyers are distributed by Shop Assistants in most of the areas. There is one in each area, not including "MOGRA", "Battle Arena", or "Shrine". The locations of the Assistants are static. Their names are purple. Each of them will give you one of the 135 total flyers. You must speak with them multiple times as you progress, as they will only give you a flyer after every few story missions. To find out if new flyers are available, leave MOGRA and check if the Shop Assistant in the connected area has a new flyer. If she does, check all locations for new flyers. This will require the storyline to be completed a few times. The amount of flyers you collected will carry over to your next playthrough
