Denka is predominantly a light-coloured brown with darker markings along his ears, on his cheeks, paws, and tail. Suigetsu when he first met them mistook the two for talking tanuki. He wears a simple blue kimono with mesh armour underneath, held closed by a simple white sash. On his forehead, is the kanji for "shinobi" (忍).
- Hina and Denka are actual names of cats that are owned by Naruto Uzumaki's voice actress, Junko Takeuchi.
- Junko Takeuchi also voiced Hina, while Denka was voiced by Kazuhiko Inoue, who also voiced Kakashi. The same goes in the English dub with Naruto and Kakashi's voice actors.
