In "Jojo's Bizarre Adventure" episode 31, Josuke was lured inside a pylon tower that will kill him if he ever tries to leave without a replacement and its possible Kira's identity will be revealed anytime soon with Rohan stalking him and sorting through photos of Kira in different disguises.
In this week's episode, the challenger is Toyohiro Kaindaichi which is also referred to as "Superfly," described as a one of a kind stand that can live independently from its user. It lives inside a broken pylon tower that provides electricity to the area around it. However, anybody who comes in the tower will automatically be trapped inside of it until another person comes in to take their place. Toyohiro Kaindaichi has been in the tower for quite a while and pretends to be a kind man and tricking men inside the tower.
Unfortunately, he was successful in bringing in Josuke into the tower and trapping him inside it. This is his trigger to finally reveal his true form as a bad man and escape the tower. Any attempt for Josuke to escape will make the tower meld his body with it which will ultimately kill him.
While Josuke and Mikitka do their best to defeat Kandaichi, Rohan and Koichi seems to be being stalked in the other side of the town.
