Hanamonogatari EP4 - Suruga Devil, Part Four

Rouka continues her explanation from the previous episode, finally revealing why she came to collect devil parts. A person came to her with a problem, and like usual Rouka planned to listen. The girl revealed that she had a monkey leg, and her wish caused her to attack her own mother, similar to Suruga's wish on her paw. For the first time, Rouka actually wanted to help someone, but as nothing more than a collector of misfortune, she was unable to do anything beyond embracing the girl and telling her it would be alright. Rouka then thinks to contact Kaiki, but discovers the next morning that she now had the monkey leg.
