You met Kunikuzushi during his walk. Guuji Yae warned you, and instructed you to run away from him as soon as you see him.

When you saw him, you unsealed your Youkai power and tried to stop him in his tracks with your powers but instead, his Kitsune abilities backfired on you.

Kunikuzushi walks over to you slowly with a cruel smile on his lips. "Haha~ Can't move? You're foolish thinking you can use your abilities on me." he says "I wonder, should I kill you now?~" he laughs mockingly
