Ueki's Seiku

Seiku (花鳥風月) is the 9 star Jingi which grows wings to the users back, enabling flight to midair. They can be combined with heavenly powers to increase its speed, like during Ueki and Hanon's fight. They don't seem to have any pattern or signs that show what power is infused with it. The only thing that varies within all Seiku's are the color of the wings.
