Stona

Stona is Kouko's second reincarnation. In this life, she is one of the spiritual leader in leading the sacrifice.

[Spoiler] In order to appease the people, Stona was forced to perform sacrifices even when she knows that the rituals are all shams. She killed Rei during the ritual and Fone when he tried to stop the ritual. Afterwards, she and her family was brutally murdered because people was convince from Fone's death that the sacrifice ritual doesn't work, reigning Fone as their hero and new god. [/Spoiler]
