Simon: IEI (possibly ILE, but I think IEI makes more sense)
Kamina: SEE
Yoko: Gamma extrovert (seems more LIE when contrasted to Kamina... not like an irl LIE, but more like an exaggerrated version of a female anime LIE archetype), possibly EIE
Nia: SEI
Rossiu: SLI (seemed ILI at first, ended up seeming more LSI)
Viral: oddly, I've never thought about his type before... and the first thought that popped into my head was ESI, but LSI is also possible, and I'm not completely confident he's Se creative
Reeron: IEE or EIE, probably
Kittan: SLE? could be SEE? could even be SLI???
Kinon (Kittan's redheaded sister): Beta rational
Gimmy: SEE maybe?
Darry: ethical, maybe IEI?
Kiyoh: ESE
Lord Genome: SLI? LSI?
