That someone may know what's best for humanity? It happened to my friends and I too back home...or in my case, will happen soon.

[But then back to Philemon...so if he was connected with personas here and this boy knew him before arriving then was it possible that he came from a world where personas existed like her friends and the group from Tatsumi Port Island?]

May I ask something? Before coming here, were you able to use a persona?
