A black-clad intruder wearing a fox mask who attempted to interfere with clearing Abyss. Used dual swords with purple lightning, similar to Sumeragi Kuon's Two-Blade Purple Lightning style. Wore bulletproof-specialized gear that completely blocked magic gun attacks. Was defeated by Hinasuu's Kamijiki-Style Hiten Kagura but survived and fled toward the exit. Was later knocked down by a shockwave when the real Sumeragi Kuon arrived. Was an imposter, not the real Sumeragi Kuon.
