Shinobu Time, Part Two Episode 18

On New Year's Day, Kaiki receives a call from Hitagi requesting for his services. After claiming that he is in Okinawa in an attempt to shake her off, Hitagi affirms that she will take a flight to meet him there, forcing him to do the same to keep his lie from being exposed and Hitagi from killing him. Once meeting at the airport, Hitagi explains their problem with Nadeko - she wants him to deceive her into letting them live as the day of their graduation and battle with her approaches. Despite seeing how Hitagi is desperate enough to resort to asking a man she loathes and that she is prepared to attend whatever demand he asks, Kaiki claims that he has no reason to help them at all before considering their connection with Gaen's niece Suruga, causing him to accept Hitagi's request.
