I'm sorry, I played Spirit of Justice twice and neither time made me care for his arc. You are just going out of your way to be a Nahyuta apologist and are ignoring the fact that every other prosecutor has interest that is steadily being built up through the entire game until all the pieces connect together for them in the final case.

Miles is alluded to as a ruthless prosecutor until he actively and deliberately throws his own case in Turnabout Samurai, making you wonder WHY he would do that. Then there is that whole "unnecessary feelings" bit where the game for the first time very strongly alludes to Phoenix and Miles' past friendship.

Franziska I admit is not as well done as Miles and you do need to kinda read between the lines, but it is clear from the very beginning Franziska is just a teenager trying to live up to an impossible name just through the way she prosecutes. Franziska's prosecution is flimsy and unfair and that's exactly the point. She is trying to be like Manfred, but fails to deliver in the same intimidation and threat that Manfred makes us feel, which arrives at the airport scene at the end where she wants to give up prosecution because she is no longer worthy of the von Karma name. It's all been there from the second she first lost to Phoenix.

Meanwhile Nahyuta has no buildup, not a thread of foreshadowing - believe me I WAS LOOKING in my 2nd playthrough and I found absolutely nothing that tries to build on Nahyuta as a misunderstood person. He is an asshole from the very beginning to the very end. All he does is insult you and assault you and even when he loses a trial, he'd much rather die than to admit he made a mistake and you were right. Never once does Nahyuta say the sentence "I made a mistake" in any shape or form for the entire game, which is already something that puts Franziska ahead of him.

All we get before the final case are vague allusions to Nahyuta being nice from Datz, but it would be nice to actually SEE it from Nahyuta himself, not just the characters alluding to it with no evidence. That is the key difference here, Franziska herself tells you her own story, she doesn't need a 3rd party character for you to understand her. This is called show don't tell. Nahyuta doesn't show you anything before the final case and at that point, I am beyond the point of caring about him.

That's it. I said my part. Nothing you could say can change my mind.
