Ero-neko

Ero-neko is a small, deceptively adorable phantom tabby cat frequently spotted near the school attended by protagonist Hibiki Amanai. To ordinary people, it appears to be nothing more than a harmless stray meowing innocently—but beneath that cute exterior lurks the soul of a thoroughly shameless, lecherous old man. Only Hibiki, blessed with a unique spiritual sensitivity, can decode the cat's outrageous and inappropriate commentary. Ero-neko's favorite pastimes include sneaking into girls' locker rooms and scheming to catch glimpses of women's underwear, making it one of the story's most notorious comic-relief troublemakers.
