Over Time

This is about a lazy baseball player, Taro, and a very serious baseball player, Takami, who want to make it to the top. They cross paths on a bus that crashes. Takami dies and Taro lives. Taro visits Takami's grave and sees Takami's ghost. His ghost tells Taro to "switch" with him and take him to the koshien to fulfil his dream.
