Silken Plumage Six-Star Evolve Gem

The purest astral gem can Evolve the Senshi "<Silken Plumage>Sheru" to a higher star level.
It can be given to Senshi through the "Give Gift" button in the Senshi interface, and can increase the star level up to Six-Star.
You must own a One-Star Senshi before you can give this gift, and it increases the star level by one each time. After Evolving, the existing star energy will reset to zero.
