It is the first game to be developed by CyberConnect, as well as the first installment in the Little Tail Bronx series, which takes place in a steampunk fantasy world of floating islands populated by anthropomorphic dogs and cats.

The game revolves around a teenaged canine police officer named Waffle Ryebread and his encounters with the Black Cats Gang, a group of sky pirates who aim to steal magic crystals.

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.

Players control the character Waffle, who pilots a semi-humanoid mecha called the "Police Robo" with the ability to run, jump, climb on ledges, and hover in mid-air for brief periods.

[5] The game features a variety of levels, each with their own objectives that usually involve capturing enemy kittens by grabbing them with the Police Robo's limbs, as well as boss battles that take place at the end of certain stages.

[10] Due to its unique geographical configuration, the nation's inhabitants mostly commute by way of airships, and their society is characterized by steam-based technology and mysterious crystals culled from the ruins of an ancient civilization.

[10] The story revolves around a young canine police officer named Waffle, and begins as he investigates a public disturbance caused by the Black Cats Gang on one of Prairie's islands.

After speaking with his grandfather Russel, Waffle learns that the crystals once served as the power source for a colossal robot called the Iron Giant which nearly destroyed the world centuries ago in a great war.

Thinking the cats want to revive the giant themselves, he discovers that the gang is unaware of the crystals' purpose, and were only gathering them on behalf of their financer and weapon supplier Fool, who tricked them with the promise of getting revenge on the dog people for years of prejudice.

However, they expressed concern that the developers responsible for translating and localizing the title may not be able to complete the game on time, citing it as "the only factor that would make Tail Concerto not see a release on these shores".

[20] Although delays caused the title to miss this date, Atlus later made a statement on their website that they would begin shipping the game to retailers on November 3, and for players to expect it in stores shortly thereafter.

[24] Peter Bartholow of GameSpot called attention to the Japanese import's "pleasant and light" presentation, deeming it "a 3D platformer perfect for gamers of all ages", but ultimately felt that it lacked challenge and was too short.
