The Lungfish (肺魚, Haigyo (tenative name)?) is a narrative character in Kanojo, Okarishimasu and the spin-off manga Kanojo, Hitomishirimasu. It is a pet lungfish owned by Kazuya Kinoshita that lives in an aquarium with at least two other lungfish. In the story, it serves as a commentator, mostly criticizing its owner Kazuya.
The Lungfish was originally mistaken by some sources to be an axolotl. Its species is clarified as it introduces itself in the first chapter of Kanojo, Hitomishirimasu.
