ダニエル, Danieru
Accompanying Momo is a talking black cat familiar named Daniel with a bell around his neck and batlike wings who helps Momo out. The living frequently hear the ringing of Daniels bell when Momo and Daniel are nearby. Daniel has a calm character and does not show as much sympathy to humans as Momo but is still patient with them. In the TV drama Daniel is portrayed as a young boy rather than a cat. Wikipedia
