What do I use for this? What I have in mind is Transmigrators Association since they were summoned from another world. Is this fitting? Or should I change it to Reincarnators Association? Many thanks. 転生者会
Transmigration is more like governmental or NGO attempts to move people from a crowded region to another less populated region. Reincarnation is more about putting souls in new fleshy bodies. I also propose Metempsychosis and Metempsychoser(?) as an alternative

Eh?
