Riding Bean is an anime Original Video Animation following the exploits of courier-for-hire Bean Bandit and his partner and gun(wo)man Rally Vincent.

The anime follows one day in the life of Bean and Rally, as they find that they have been framed for the kidnapping of Chelsea Grimwood, who is daughter of Mr. Grimwood, President of the Grimwood Company/Grimwood Conglomerate. However, it is Semmerling, by way of various disguises, tricks, and manipulations, that is the real kidnapper. And the real target is Mr. Grimwood himself. While the police are in hot pursuit of Bean and Rally, along with Chelsea in tow, Semmerling and her helper/lover Carrie plan to make a secret getaway with Mr. Grimwood as hostage. This is a tour-de-force involving a purposefully-blundered bank heist, voice alterations, disguises, and an unusual job offer to transport the kidnapped girl to her home, all orchestrated by the criminal mastermind Semmerling (her name comes from the gun she carries).

Riding Bean was followed up by the anime series Gunsmith Cats, which focuses on Rally and her bounty-hunting partners. More accurately, Riding Bean is essentially the Pilot episode for Gunsmith Cats.

Riding Bean, it is rumored, was to have been the first in an anime series by of same name. However, Sonoda had a fallout with Toshiba EMI over the series (rumored to have been mostly on the part of Toshiba EMI), and thus the series ended with only one "episode." Toshiba EMI retained the rights to the series, and Sonoda was forced to abandon a direct port of the franchise to what became Gunsmith Cats, which seems to be a sort of prequel to Riding Bean. Again, as is self evident, characters and concepts were ported over and a new plot was devised.

• In Gunsmith Cats, Rally is a dark-haired, dusky-skinned woman who works as a bounty hunter(and gunsmith, hence the name). She usually works on the opposite side of the law as Bean, but considers him a friend. In one story, she races against Bean to get him to stop working for drug dealers. Rally's signature car in GSC is the Shelby Cobra used by Percy.
• Bean's custom car is named 'The Buff.'
• Semmerling seems to be the prototype of Rally's manga arch-nemesis, Goldie Musou, a powerful Mafia Queen who has an entire harem of drug-controlled young girls.
