Japanese name:	キセニアン
Nickname:	Kisenian Blossom

The Xenian Flower has to destroy stars and planets to survive. Alone, she holds no power. Thus, she needs a host, preferably someone with a 'vulnerable heart' (like Fiore). Luna calls the Xenian the 'most dangerous flower in the universe', and Artemis says that hundreds of planets have been destroyed in this galaxy due to a Xenian Flower.
