Returning from his visit at the Polar Snake Shrine, Kaiki asks Hitagi to meet him again, ending up in a Mister Donut restaurant. Kaiki claims that it will be easy for him to deceive Nadeko as at her current condition, she can't doubt anyone - she has turned even more childish than she was in her human state, unable to detect any ill will. He reveals his plan to spare Koyomi and the others by lying to her that they died in an accident, thus he needs Hitagi to convince Koyomi to cease all connections with Nadeko. Hitagi, relieved and crying, thanks him for his services. On the following day, Kaiki is approached by Yotsugi who comes with an ultimatum from Gaen urging him to pull off his scheme to deceive Nadeko, claiming that the stake is too high and the entire city may be destroyed should he fail. Despite accepting ¥3,000,000 as compensation from Gaen, Kaiki moves on with his plan and pays another visit to Nadeko, claiming that he has a special wish she can fulfill and he will keep visiting her in a 100 visit cycle. Nadeko cheerfully tells him that she destroyed the cat's cradle yarn and used a white snake instead. Terrified, he determines she is not only an idiot, but also insane. After the meetup, Kaiki tricks Nadeko's parents to have them leave their house and he takes the opportunity to investigate her room, getting startled upon finding out what she kept hidden inside her closet.
