She was a bit of a stability in an otherwise chaotic web of relationships. They made her a source of strength for the player, but I never thought she was completely safe... especially after the subversion they did for Sayaka's character.
That's how I see it.
Kyoko wasn't perfect; she got valuable information because she took massive risks and almost died because of them.
???He was, I agree. Which I think comes off as a bit phony overall.
The phoniest thing is how Byakuya and Kyoko know 100% of what is going on at all times and basically refuse to let anything go wrong. Sorta takes the tension out!
Byakuya was mostly in the dark for the latter half of the game. He falls for Monokuma's pathetic group picture gambit, and outright denies the possibility of Junko being killed twice.
Kyoko's gambling, but she is the only one who actually knows what is going on. She's also at that point called it out as a trap at least twice. Byakuya might not always know exactly what is going on, but he's written in a way that really does make you feel consistently like the dumbest one in the room. I was so tired of seeing, "Well, you tell 'em, Makoto." Just really sort of weak because it makes Makoto and Byakuya feel like showrunners.
That's just in his nature; Byakuya's an arrogant asshole, (even when he's in the dark) but at least he manages to give credit where credit is due by praising Makoto's overly nit-picky nature.
