You know… Kaito being a Kid fanboy and annoying Aoko with it is used often, and that’s all well and good. But… if you think about it, Kaito’s not really the type to gush over people. Events, objects, and places I can see at times, but not really  the sort to never shut up about a person. So… I wouldn’t be surprised if the only time before Kid, the only person Kaito would bring up over and over would have been Toichi. Since he already seemed to be bugging Aoko with how proud of his dad he was.
