"The Five" is the term I use to refer to the 5 "main" characters of P37254: Fohnyx (3), Seth (7), Devon (2), Aleph (5), and Misato (4). The term is generally only applicable after is interchangible with 'the troupe', the latter of which I'll use
Actually, a little tidbit about the lore: Misato wasn't actually part of The Five until quite recently. Actually, it wasn't even 'The Five', it was just 'The Four'. The reason for this is actually really stupid, and dates back a few years, around the time I begun to get into roleplaying (click here for clarification).
It was April, 2020. I'm pretty sure I was working on my own RP server during this time, and I had come up with a character named 'Misaki.' The specifics of him aren't that important (might be on Misato's wiki page), but either way that character was basically dead by June of the same year, as he was left in limbo, forgotten, until about September 2024, when I begun considering bringing him back, and giving him a place among The Four, officialising him by the 19th of October, though the term 'The Five' hasn't really.
