The worst possible side-quest available in this series, it is available as early as Volume 1: Rebirth. After completing the quest given by Bikman, you can find him in the Alchemy district. Talk to him to receive flyers. The whole goal of this side-quest is to give flyers out to the other PCs (the actual NPCs that can't be in your party but flood the cities and areas). There are 135 PCs in total you have to give flyers to, but any that you've talked to prior to the side-quest will count. It would be better to clear this out as early as possible, since it does guarantee you don't have to contest with even more in the later volumes. You will find them between Mac Anu, Lumina Cloth, inside areas, and sometimes between both cities.
Should you have issues with the PCs not appearing at all, despite hours spent loading and reloading an area, try turning the game off and then reloading it. That's how I managed to find the last I needed, EXILE (Male Human). You can also find PCs in the @Homes for Moon Tree and Kestrel, so make sure you check them.
In regards to exploring the Areas, one thing to note is that when you're composing a field up, there are two numerical readings near the keywords up top. The left one is the total amount of PCs already in the area, while the right one (the one with the heart) relates to the number you've interacted with before. This will be a life saver when hunting down the Medic Union (beast tribe members) found in the Fields.
