Miroku

was the previous high priestess of the Land of Demons and Shion's mother.

Background
Miroku wanted Shion to live a normal life and prevented her from learning about her true powers, and as such prevented her guards from teaching Shion any ninjutsu. But to protect her daughter, she left Shion a special bell to contain her powers and protect her. However, to save Shion's life, another one must usually be sacrificed in her place.

Eventually, Miroku and Mōryō came into conflict, and when the demon tried to absorb Shion in place of Miroku, the mother sacrificed her own life to save her daughter and seal away Mōryō.

Personality
Miroku was a very kind mother that cared deeply for her daughter.

Appearance
Miroku had pale skin with very long brown hair and light-coloured eyes.

Abilities
Miroku was well-versed at fūinjutsu, having sealed Mōryō. She also gave Shion a protective charm bell, which was imbued with powerful protection for her daughter, and to assist in sealing Mōryō.
