Taken from his game, headcanon/personal playthrough/guesstimates. Demons will come later, since at
vatheon he doesn't have them anyway.
As Naoya (as seen in Amane's route boss battle against him
HERE, which has SPOILERS) is a cheating jerk who created the COMP's Demon Summoning software, programs, and all the coding for everything therein, he has resistances like a demon all his own, and the abilities to match, as well as the ability to switch his skills as often as he likes in RP. He can and will at any time reserve the right to change these abilities immediately, because he's cheap like that. Therefore, a → denotes a slot that should not exist, but Naoya has for these abilities only as per canon. [EXTRA] Indicates a skill he is likely to use but swap one of the original slots for should he need it.
List of abilities and what they do can be found
here, for reference.
