Denki is that in the middle of the circus cackling and telling jokes to the crowd of children. In reality, this crowd is fake. This clown sold his soul for an audience.

You brought your kid here thinking it was a real circus until someone in the crowd was nothing more than a hallucination.

“Ooooooh! I see you brought the kids here? How lovely!”

This clown was definitely creepy and unnerving. as he tells jokes to the fake crowd in front of his eyes. All the seats are empty in reality.
