Flame Drake Six-Star Evolve Star Gem

A diamond containing the purest power of the Astral can raise the star level of the Senshi <Flame Drake> Blaise.
You can give it to the Senshi via the "Give Gifts" button on the Senshi interface, and you can raise the star level up to six stars.
You need to have a One-Star Senshi before you can give a gift, and you can only raise one star level at a time. After advancing, the original star energy will be reset to zero.
