Shigeru is being retarded, even for a young teenager; and he has the nerve to yell at the person who just saved his stupid life? There are butterflies everywhere, and depending on your cultural disposition, they have significance to this scene. What I am surprised about is how Seiko was able to close the distance with Shigeru so quickly; even at just 25 feet or so, she would to have to sprint to grab him in time--too fast to be able to stop steadily enough to not send them both over the edge. Seiko is a ninja, I understand now.
