And once again we go back in time!
From helping Sodachi in October to right after summer break in August, the final blank space to fill up of that time frame after having watched Tsubasa Tiger, Mayoi Jiangshi and Shinobu Time.
Funny how Nisioisin originally had plans to tell this story during the Shinobu Time arc in Onimonogatari, but in the end it would be too much and it became its own book and one of the lengthier arcs.
