Crimson Flame‧ Six-Star Evolve Gem

The purest gem of Astral power can evolve the Senshi "Dragon Flame Valkyria".
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 gifts, and you can only increase one star level at a time. After evolving, the existing star energy will reset to zero.
