I wanted to talk about the inui-is-ken-theory
So there's a fan-theory that noboru inui from persona Trinity Soul is ken amada. Everytime inui gets mentioned, it's in posts talking about this theory. Hell, it's even mentioned on the trinity soul wikipedia page.
But I do get where everyone is coming from. Nothing really contradicts the theory, Anyway.
The evidence that inui is indeed ken is:
They both have brown hair, They have a similar haircut, Inui likes dogs (But everyone likes dogs, so that isn't exactly concrete evidence), inui lived with persona users as a child, and he knows Akihiko (Inui even knew that Akihiko was a champion boxer). But none of these points are really concrete evidence and it could just be a coincidence.
Anyway, the ages do align, though. Inui's age was never actually confirmed, but he appears to be in his early-to-mid-twenties judging by how he acts and looks. He definitely isn't a teenager but he seems to be younger than akihiko. And Persona 3 takes place 10 years before Trinity Soul, so Ken would've been 21.
And this theory makes more sense than Ken being Akechi. Sorry, but I don't think that Ken would do the things that Akechi did. Ken would be more like Akechi if S.E.E.S. didn't practically adopt him, though.
Also, in Persona 4 Arena Ultimax, Ken is the only character that references Trinity Soul. He has a palette that makes him and Kala-nemi look like Jun Kanzato and Seth, but not inui and his dog.
I thought that if someone got a Trinity Soul palette, it'd be Akihiko as he actually appears in the anime. Like, akihiko would get a Ryo and Caine color palette or something.
My thoughts? I haven't really thought of this much and I'm mostly neutral about this theory, but I do find it pretty interesting.
