Uroko Araundo

The daughter of Izuko Gaen. Her father is unknown. She is the cause for many snake-happenings that Sengoku Nadeko has to clean up after. Uroko is the "head" of the snake, and so Izuko tasks Nadeko with quelling the wild snake. It's said that Uroko is afflicted with snake scales. Uroko's limbs are covered in snake scales due to a curse. Though Izuko and Kaiki Deishuu refers to her as Izuko's daughter, Uroko isn't quite that. Her existence is actually akin to Ougi Oshino or the Rainy Devil; she is Izuko Gaen's other side. Izuko never killed her other side like Tooe Gaen did to her own, nor did she accept her other side like Koyomi Araragi did with Ougi Oshino. Instead, Izuko let her go off and do her own thing; when Izuko became the head of the specialists for good, Uroko had become the head of the serpent and had to do the opposite. When Nadeko, Kaiki, and Yotsugi Ononoki came to stop her, the plane they were on is brought down by Uroko. Ultimately, Nadeko faces Uroko and frees her from cursed limbs, making her into a normal girl. She later attends high school and lives a normal life.
