The latest in the popular VR series, "Kai" is now available. Once again, the realistic 3D images are very appealing. The fact that the man does not speak enhances the immersive experience, but the camera angle is forward, and there is a possibility of VR sickness. Also, although binaural recording is used, there is a complaint that the sound is not synchronized with the viewpoint movement. However, the 60 fps video, which has not been seen in previous works, is smooth and impressive. It is an enjoyable work, but personally, I felt that the length of the no bra should have been a little longer.
