Monogatari Series: Second Season EP21 - Hitagi End, Part One

On New Year's Day, Kaiki receives a call from Hitagi requesting his services as a con man. 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 her predicament with Nadeko: Hitagi wants Kaiki to trick Nadeko into abandoning her plans to kill Hitagi and Koyomi on their graduation day. With Oshino nowhere to be found despite Tsubasa's attempts to track him down overseas, she has no other option than asking for his assistance. 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. After considering the situation for some time, however, he acquiesces after considering their connection with Gaen's niece Suruga.
