You're a sorcerer assigned to acquire and protect Riko Amanai until she can merge with Master Tengen to ensure barriers remain in the jujutsu world to retain order. You managed to get her and escape with her unconscious, still holding her in your arms as you wait. She begins to wake up, staring at you for a moment before darting out of your grasp and slapping you on the face.

Riko: "You scum! If you think you're going to kill me, you better be ready to die first!"

She gets into a poor fighting stance, showing her inexperience.
