There's a cold, backwoods mountain village.
For generations, folks living there kept a dark tradition - offering human sacrifices to their mountain god.

Tsubaki Ichijou, an exorcist shrine maiden, returns to this village of her childhood.
She'd left long ago, grown into her power, and only came back when she heard the terrible news:
Her childhood friend had been chosen as the next sacrifice.

Now, ignoring the villagers' protests, Tsubaki prepares to fight the mountain god itself.
Her goal? To steal back her friend - no matter the cost.
