For ID: INVADED that phrase was supposed to be the detective's way of remembering who he was since he loses all memory in the dreams. I totally get how that would be annoying though lol
As for Deca-Dence.. That second episode throws everyone off lol I was feeling mixed on it for a few episodes after that too and almost dropped it, but halfway through the season was enough to have me stick around. Both sides of humans and cyborgs have their conflicts and manage to impact one another, it's actually pretty cool.
And Appare-Ranman! That's literally my favorite anime this season, it's the one anime I look forward to watching the most every week. I know the premise isn't the most appealing, but if you keep with it, the moments that the characters have with each other is just perfect. Just a big old chef's kiss on that show
