Hitagi End, Part One Episode 21

Kaiki returns to his hotelroom and finds an envelope with an anonymous message telling him to pull off. After tearing it up and flushing it in the toilet, he contacts Hitagi, telling her about the incident with Gaen and Yotsugi. He asks her if anyone else could profit from having him stop his plans to deceive Nadeko, however she has no idea who could have such goals. She asked if she could see the message, but Kaiki noted that he destroyed it already. Before hanging up, Hitagi warns him to beware of Nadeko. On the following day, Kaiki pays another visit to Nadeko just as promised, but this time he offers ¥20,000 and a bottle of sake instead of the usual ¥10,000, much to Nadeko's joy. Returning from the temple, Kaiki is approached by Hanekawa who wants to talk to him. As they return to the city on a cab, Hanekawa reveals that she had just returned from her search for Oshino overseas without Hitagi's and Araragi's knowledge and even though she knew that continuing to look for him is futile, she intends to depart again on the following day. It turned out that Gaen personally warned Hanekawa to stay out of the intrigue. She invites Kaiki to her hotelroom. Kaiki, after making sure she is on their side, suggests her to exchange information with him.
