Hitagi then arrives and apologizes to Koyomi. She reveals that Mayoi does not exist, as she is actually dead. As a ghost, she can only be seen by those who have a subconscious desire not to return home.

At the study session with Hitagi, the two discuss their future after high school, but things quickly deteriorate when Koyomi mentions Suruga. Hitagi and Suruga were friends in middle school and Suruga may have even had a crush on her, but they had a falling-out in high school.

On his way to Oshino to drop Hitagi's payment off, Koyomi is viciously attacked by a person wearing a rain coat. During the fight he sees that the assailant has bandages dangling from its left arm.

She apologizes for beating him up the previous night. Koyomi asks about her unnatural strength, and she reveals that she literally has a monkey's paw. She also bluntly states that she is a lesbian, which is hard for Koyomi to swallow. Koyomi then takes Suruga to visit Oshino for help, where he determines that the arm is actually a lesser devil's, since a monkey's paw doesn't attach itself to its owner. As such, the arm will take Suruga's soul once three wishes are fulfilled.

EP8 - Suruga Monkey, Part Three

Inheriting a mummified hand from her mother, Suruga first wished on it in 4th grade to run quickly so that she could win a local race. Soon after, four of the competitors were hospitalized due to an assault from a monster dressed in a raincoat. Suruga suspected the hand may be acting like a monkey's paw, wherein a wish is granted in an unexpected way. She abstained from wishing upon the arm for many years, coming close once to wish for help with Hitagi's crab problem, but it's stated that such a wish would probably not have been granted, as the arm only manifested negative wishes, especially the hidden intentions of them (the students being beat up was revenge for Suruga being outcast). However, after seeing Koyomi and Hitagi in a relationship, she became insanely jealous, and wished upon the arm to be with Hitagi, without noticing that the hand had grown into an arm and attached itself to her. Oshino surmises that her first granted wish had already caused the devil to take a portion of her soul, leading to the hand's growth. He offers the solution of cutting off the arm, a suitable price in exchange for nearly killing Koyomi (a result of the hidden side of her second wish). Koyomi objects to this, and instead, opts to defeat the devil to dissolve its contract. To prepare for the fight, he gives some of his blood to Shinobu in order to boost his limited vampiric powers. Despite that, he still gets literally shredded apart by the devil, and is saved at the last moment by Oshino's intervention. He called for Hitagi, who notes that Koyomi had hidden the entire situation from her, against his precondition for their relationship. With her appearance, the devil is unable to continue the attack without invalidating either half of the wish, so the contract is dissolved. However, even though the devil is gone, her arm still hasn't fully recovered. In the end, she becomes good friends with both Koyomi and Hitagi.

EP9 - Nadeko Snake, Part One

Koyomi and Suruga travel to an abandoned shrine in order to perform a job for Oshino. As they climb the mountain the shrine is located on, they pass a girl running down the path, who only briefly exchanges glances before continuing in the other direction. Once they reach the shrine, Koyomi and Suruga discover a number of dismembered snake corpses in what appears to be some sort of ritual. They both quickly decide to leave. The next day, Koyomi and Tsubasa go to a bookstore, where they begin to converse. Tsubasa warns Koyomi that he and Hitagi must set down boundaries in their relationship if it is to last. She then leaves after getting a sudden headache. Koyomi then meets the girl again, who he finally realizes is Nadeko Sengoku, a friend of his sisters whom he met as a child. He and Suruga intercept her at the shrine, and return to Koyomi's house. Once there, Nadeko takes off her clothes, revealing snakelike skin, and pleads for Koyomi to save her.

EP10 - Nadeko Snake, Part Two

Oshino informs Koyomi that Nadeko is under the effects of a Snake Constrictor, a snake spirit that slowly constricts the life out of its victim. Nadeko explains that it is a curse a classmate placed on her after Nadeko inadvertently rejected the confession of a boy the classmate liked. Normally, a curse placed by an amateur would be harmless, but Nadeko accidentally made the curse worse by performing her ritual at the shrine, which has been corrupted by Shinobu's presence. Koyomi obtains a special charm that will banish the Snake Constrictor and they return to the shrine. While the ritual is seemingly successful, Koyomi realizes that Nadeko is under the attack of two Snake Constrictors, the second being placed by the rejected boy. While the first one is banished, Koyomi is forced to battle the second to keep it from killing Nadeko. He and Suruga manage to chase it off, but Koyomi feels guilty for not being able to destroy it, as the Snake Constrictor will return to the person who originally placed the curse.

The cat soon escapes from Oshino, then goes after Koyomi; this time, however, she sides with him and aids in searching for Shinobu. The two have conversations regarding Koyomi's interactions with oddities while they scour the city. The search proves to be difficult even with the cat's keen sense of smell and hearing. The conversation gradually switches over to Tsubasa's situation. The cat explains that there is a way to confine her without relying on a vampire, that she is the personification of Tsubasa's stress, and that she knows exactly what is causing it. She remarks that Koyomi can deal with it easily. The oddity then reveals that Tsubasa being possessed by the cat was because of the stress that she felt from her unrequited love for Koyomi, and that the oddity itself may be sealed away for good if Koyomi falls in love with Tsubasa.

Koyomi is confused after hearing that Tsubasa loved him as he heard from the cat. After arguing with the cat that it was a mistake, the cat tells him that there is another way to suppress the stress for good, to kill him.
