Three years later, a documentary film crew led by Koji Shiraishi began a project chronicling the aftermath of the incident and interviewing survivors.

To the crew's surprise, Eno states that he is thankful that Matsuki stabbed him as, in the aftermath, he has experienced "miracles", such as UFO sightings and disembodied voices.

Seeing that Eno is financially troubled, the crew agrees to let him live in their offices and pay him on the condition that they are allowed to film the phenomena he witnesses.

According to horror film director Kiyoshi Kurosawa, Kutoro Rock was dedicated to Hiruko, a Japanese god with the form of a leech.

Meanwhile, the film Eno shoots following his daily routine reveals that the "UFOs" he sees are, in fact, leech-like apparitions that appear in the skies above Tokyo.
