Tooe Gaen, was the sister of Izuko Gaen, the wife of Suruga's Father, and the mother of Suruga Kanbaru. It was later revealed that Suruga's parents eloped at some point during Suruga's elementary school life, as the Kanbaru family did not approve of their relationship. She and her husband died together in an accident. By the time of her death, Kanbaru will have received a "monkey's paw" (the Rainy Devil's left arm) while Deishuu Kaiki will have been entrusted with the Rainy Devil's head. Tooe's possession of these two artifacts imply her strong connection with oddities.
