Suzaku's entire motivation is to FREEEEE JAPAAAAAAAAAAAAAAAAAAAN. Very community-based. And do it in the most retardedly incompetent way. Because otherwise ZOMGZ PEEPULZ WILL DIE. His entire life is centered around this Ni-Fe idealistic vision.
That, and he clearly has Se as well, being very physically adept (in fact, he could be ENFJ come to think of it -- he's far better at situational awareness and physical action than Lelouch is).
And Why Ne Fi?
Half his internal dialogue consists of zany connections. As he has a visibly very strong Te, and appears to actively suppress his Ne, I believe him to be Ne-dom.
