@Xeiyenreisha if it doesnt work then she will probably give her spare to someone else to help out when someone is being stubborn enough (Shinrei maybe?)
and Hayato never takes the hammer so there is that
Shinrei is probably the most stubborn out of all the characters. I mean when he entered the Duel Tower he acted like almost everyone was nonexistent as he made his way through only to have his sister drag him off to watch the duels. I bet Hayate is one of those ones who will keep repeating themselves around camouflaged mind people who act like nothing exists around them until they acknowledge them, correct?
