Blood Coral Crystal

The blood coral crystal, passed down from generation to generation of the bat demon clan (Hyakki Mori clan), is used by their current guardian to create a barrier to protect the clan. The stone contains all the souls of previous bearers within the tribe.

Powers and Abilities
The crystal can erect a barrier so strong it could withstand the Kaze no Kizu (Wind scar) easily and even withstand the backlash wave though it was temporarily weakened by the latter.
