In one of the earliest episodes of Diamond is unbreakable, Koichi is pierced by the arrow which awakens stand powers. He was badly injured, and Josuke stated he was going to die, so he cured him with his stand. However, Koichi awakened his stand, and it's said that few who are pierced by the arrow and survive, they awaken a stand.
So, was he supposedly going to die, or was he supposed to survive because he awakened a stand even though he was badly injured and unconscious?
