OH about the finale at the shrine, this completely slipped my notice when we were talking about it, but Ichi says he's "reporting" Jo's verdict to both Arakawa and Masato. It's just not translated that way.

Not too big of a difference (well, it is to me, but I'm insane), but if it was highlighting anything, I'd guess it's probably Masato's change of heart. It would've been fair for Ichi to assume Masato wouldn't care and only "report" to Arakawa, but in the context of Ichi doing his damnedest to show Masato they all love him, it works in terms of, "Maybe I made him reconsider, and maybe now he would care."

Also... I'm looking at it in a "measured" way, since the chapter trophies are always just standard "Nth Chapter Cleared" messages that the localization team just spices up for us, but there's something I find really poignant about the Chapter 13 trophy being worded as "Fate of Our Fathers." The pluralization of both the noun and pronoun. Realizations that come too late.

Of course, Masato definitely didn't "know" and had no real reason to suspect it, but the Arakawas have this bizarre subconscious almost-psychic link. So even if he doesn't really think so, there's this sense that Ichi "might as well" be Arakawa's "real" son because they're so much more alike. And maaaybe he felt that way about Jo and himself at one point, because (as we've discussed) there has to be a reason Jo was Masato's "favorite."
