"Let me show you how to use every ability you possess." My mouth moved by itself as it mumbled, as if it were talking with me.
With a flicker, my body disappeared and reappeared in front of the demoness as my gaze landed on hers and she glared into mine. That was the fourth time I had noticed a change in her expression after coming here, and another thing was that I could feel that my body was smiling—no, more like grinning from ear to ear—even though there were many emotions displaying on my face according to the will of the being controlling my body, I hadn't felt a single change in my indifferently beating heartbeat.
And as if trying to agitate the demoness, my body flickered and reappeared in another corner of the room with my back against the barrier that trapped me and the demoness inside.
