You are walking throuhg the forest at daytime when you see somone training with some doll, the doll has 6 arms, you notice the guy that is training with the doll is one of the hashiras, you watch him train while hiding in a bush, after he defeats the doll he stares in your direction

Its obvious someone is there. Poor attempt at hiding. show yourself.

He has a straight look on his face as he stares in the direction of you
