Nisemonogatari EP2 - Karen Bee, Part Two

On the same day, only a while after parting ways with Mayoi, Koyomi arrives at Nadeko's to spend some time playing with her, despite learning that her parents are not home. Nadeko is seen styling a different hairstyle than what she previously had. They spend their time talking and playing games. Nadeko becomes frantic after hearing her mother come home because she did not tell her that Koyomi was coming over. Koyomi leaves Nadeko's house and then decides to call Suruga about her asking Koyomi for help in cleaning her room. On his way to Suruga's house, Koyomi meets his sister, Karen, who is in a rush doing some "community service" before leaving in a hurry after receiving a phone call. Koyomi then visits Suruga to find an unexpected sight.
