He is one of the main protagonists of the anime and web manga series. He is in Nanba Prison for starting a gang riot in a city.

Born to a wealthy family, Rock rejected his dad as his dad wanted Rock to be like him. Running away from home, Rock was arrested and sent to juvenile hall for starting a gang riot, but escaped because the food was terrible. Rock was then arrested once again and was sent to prison, only to again escape due to the terrible food.

At an unknown point in time, Rock was placed in a prison cell by himself and was starved. It was then that Rock met Jyugo who freed Rock from Prison. Jyugo then brought Rock to a nearby restaurant to fill up his stomach. Rock now claims that it was because of Jyugo that he came to enjoy and appreciate food.

At some point, he met back up with Jyugo, who was with Uno, in Las Vegas while he was trying to find Nico, who took his money and abandoned him at a restaurant, which left him in trouble for doing a dine and dash. Nico didn't mean to leave him but got distracted easily. It is also stated that he was sent to cell 5 before he went to cell 13 with his friends.
