In an age of science in reasoning, gods and youkai were considered myths of the past.
However, behind the scenes, the forces of good and evil were always in motion.
Those who fought to defeat the youkai were known as "Taimashi" or exorcists.
One summer, Koyori was called upon by her exorcist mother
to journey to a village and defeat youkai there as part of her training.
Unable to spend time with her friends that summer, she begrudgingly made her
way towards the village.
