Chai - a relatively low ranking member of the Chi You Men, Chai manages to over hear Ryo talking about having the Phoenix Mirror and attempts to steal it from him to curry favour with Lan Di.

Goals
The Chi You Men are attempting to get their hands on a set of legendary mirrors which can be used as a treasure map using light reflections. To this end Lan Di was sent to retrieve the Dragon Mirror from Iwao Hazuki, although he was seemingly unaware that Iwao also had the Phoenix Mirror in his possession.

It is rumoured but not confirmed that these mirrors will allow them to resurrect a legendary chinese diety known as Chi You that was said to devour the world and show the way to a new one.
