According to Shizuku, it's the "Giant Man-Eating Ox Demon" that was rumored in the neighboring country, with an extraordinary physique and a face with four fangs and six protrusions, called "Ox Demon" from the Nanboku-chou tag game. When Tokiyuki's group went hunting, they suddenly encountered it, and before they named themselves as the "Escape Youth Party," it became a life-and-death battle opponent for them.

Although the arrows shot by Kojiro and Ayako didn't cause significant injuries, thanks to Shizuku's strategic use of the terrain and the capabilities of Tokiyuki, Kojiro, and Ayako, they were able to make it fall to its end by a trap leading to a "Blade of the Gods" carved from an obsidian boulder.

Moreover, according to Shizuku, it was a lonely remnant of an ancient beast without a family to carry on its lineage, and if it hadn't been so lonely, it probably wouldn't have fallen into a demonic path of eating humans. Afterward, it was supposed to be dismantled to fill the group's stomachs, but it was completely eaten up, thanks to Yorishige, who had already foreseen that future and stole it entirely.
