Character archetypes for VLR?

it's been known that the characters in 999 were based on the enneagram of personality during development.
in ztd, the focus to me seems to be defined more around decisions, with the characters within each team acting like a good angel and bad angel to the more uncertain and deeper thinking team captain, with akane and junpei being the most obvious such pairing.

is there a similar system or archetype that governs personalities in vlr? could characters be based on something like prisoners dilemma strategies, eg from axelrods tournaments? dio would be a defector and luna a cooperator in that case, and sigma could be random given the players freedom of choice, but i cant put a real label on any other character in that sense so im unsure.
