Snow White -Star Six-Star Evolve Gem

The purest power gem of the Astral can evolve Senshi "<Snow White -Star>Muse".
It can be given to Senshi through the "Give Gift" button in the Senshi interface, and can evolve the star level up to Six-Star.
You must own a One-Star Senshi before you can give gifts, and you can only evolve one star level at a time. After evolving, the existing star energy will reset to zero.
