After a small investigation I have found that Shion Sonozaki is in-fact a protagonist of the series, and after reading a few episode transcripts I can see why you were concerned, she is borderline insane/the evil teammate. Basicly the story is she was tortured when she was young and it warped her more than a little, however other than one or two traitor story arcs where revenge was on the menu what I found suggests she is genuinely on board with helping the series protagonists. It's the sort of situation with a villain protagonist who would be a regular villain if not for the regular protagonists. But thanks for bringing it to my attention, these sorts of things always deserve a closer look.
