Find the Wind

During the hot summer in Tokyo, all the inners except for Usagi are gone and Chibi-usa is back from the future; during the hot Tokyo summer, the outers learn Haruka died in a car accident; Hotaru can't see her 'mama,' so sad. She thinks there is a way to bring her, 'papa,' back. There is a chance there will be a lot of power, is it possible with only 4 soliders to get Haruka back?
