It took Terry having a Shadow for Minato to say they're friends..... Terry is probably the source of most of Minato's headaches, but it's because of how strongly he's connected with people that he drags everybody down with him when he's down, so Minato doesn't blame him for it. There's a lot about Terry's situation that Minato can relate to, but he believes Terry is much better with people than he is, so he doesn't worry about him. Terry is fun to watch... Minato is very content just sitting back and watching Terry do his thing, even if that thing is destroying half the forest and pointing arrows at his Guests. Probably because Minato's a disappointment of an Attendant, Terry's always treated him as a person instead of an Attendant and that's something Minato appreciates too, that Terry doesn't just come in to do a request and then leave, and instead tries to show Minato something new or talk about something different each time. He gets frustrated with Minato and angry at him at times, but he's always willing to come back and talk instead of walking away forever, so Minato likes that about him.

Terry is a complete mess and Minato really loves messes; those sorts of people just feel so much more real to him.
