The Senshi of the Garden



 
 

These two senshi were only in the manga.  They were the two main avitars of Sailor Galaxia.  They were responsible for both the deaths of The desert senshi and Sailor Kakyuu. 

The are both named for Greek Symbols.  Phi is pronounced (Fai) and Chi is pronounced (Kai).  This is also how they are romanasized.
