Harike Seido

Kuni Harike Temple was built to honor Kuni Harike, who in 634 sacrificed himself to defeat the Kusatte Iru in the Plains of Foul Tears.

Deception
Shortly after his demise a Bog Hag by the name Higashato took his body and skin. Using her foul magic, she appeared many times to the monks that prayed at Harike's shrine dressed in his skin and convinced them that the only way to battle the Shadowlands was to understand it. By 1050 she had them reciting blasphemous texts and carving stone oni statues.

Idols
The monks told the villagers of the nearby Kyuden Toketsu to beware the evil, giving the peasants idols to defend against it, which would keep them safe from harm. They were unaware the idols were made in obsidian, ressembling the Kusatte Iru.
