"Tail Concerto (Japanese: テイルコンチェルト Hepburn: Teiru Koncheruto) is an action-adventure platform video game developed by CyberConnect for the PlayStation. It was published by Bandai in Japan in April 1998, and France the following December, with an English version released in North America in November 1999 by Atlus. The game features character designs and artwork by manga artist Nobuteru Yūki, and the Japanese version included the opening theme song "For Little Tail" performed by Kokia before her debut in the music business.

Taking place in a steampunk fantasy world of floating islands populated by anthropomorphic dogs and cats, the scenario revolves around a canine police officer named Waffle Ryebread and his encounters with the Black Cat Gang, a group of sky pirates who aim to steal magic crystals. Though it received a generally positive response from critics, the title was met with low sales in Japan, falling short of the publisher's expectations

Despite a direct sequel never coming to fruition, CyberConnect and character designer Nobuteru Yūki returned to the world of Tail Concerto in 2005 with the creation of the character "Mamoru-kun" (まもるくん?), a public safety mascot who first appeared in Fukuoka Prefecture's disaster-warning email program of the same name. The promotional materials for the program reveal that Mamoru-kun and his friends live in the country of "Nipon," which, along with Tail Concerto '​s Prairie Kingdom, is part of a larger world called "Little Tail Bronx." In June 2007, CyberConnect2 released promotional artwork for a new video game, which was confirmed to be a spiritual successor to Tail Concerto called Solatorobo: Red the Hunter, which takes place in the same world, and was released for the Nintendo DS in 2010.A mobile game in the same universe, Little Tail Story, was released in 2014, and there is promise of another game called Strelka Stories that is still in the making."
