Risotto was born in an ordinary batpony family. Because he is silent and has a low sense of existence, he is often regarded as a transparent pony, but he doesn’t care much. When Risotto was young, he was abducted to a sweatshop as a child laborer in a flight training class. This factory is one of the birthplaces of the infamous rainbow factory case in the future, which was organized by Anti-Harmony creatures to calumniate the Mane Six. Risotto was used as coolie in the factory and was forced to make “Rainbow” (later proved to be a high-risk magic power material, rather than Cloudsdale used as the material for weather management). But he also used his own sense of existence to secretly collect bits and pieces of machine parts, or to collect more food for other victims of weakness, and during this event ,he was found to have a sympathetic side. When the supervisor beat a child worker who was familiar with Risotto, Risotto stabbed and scratched the supervisor’s throat with a self-made metal tool, which won the chance for some child workers to escape, but he was caught and beated up by the overseer. In this event, Risotto learned the vitality and fear brought by “metal”, which laid a certain foundation for him to obtain his Stand in the future.  
About two years later, rainbow factory was exposed by local Pegasus residents, but a large number of foals had been killed due to poor environment and inhuman treatment when children were free. When Risotto was rescued, he was as skinny as a bone, and his coat and mane color were dimmed by the massive extraction of blood, which made him too weak to stand on his own hoofs. However, in the process of being treated and psychological counseling, he never said a word, and it was difficult to carry out psychological evaluation for a while. After confirming that all the physical indicators were normal, Risotto was able to return home, and his family paid more attention to him, but he was still silent and refused to interact with other ponies, his feelings and existence also seemed to be even thinner. Besides, apart from the remaining fear of the claustrophobic environment, his life did not seem to be greatly affected until he was 14 years old.  
At the age of 14, Risotto moved to Napmules city. In the same year, his cousin was killed by a drunk sky carriage driver. Unexpectedly, Risotto broke out in a rage, beat the driver violently and nearly beat him to death. As a result, he himself was put into the juvenile penitentiary. Four years later, Risotto was released. After learning that the driver had been punished by law, but had no regrets about his actions, Risotto was furious again. But this time, he made a careful plan, and finally killed the driver. He also got a permanent mark because of this - his Cutie Mark was born from this event. After that, Risotto, perhaps out of deep fear of the rainbow factory, was afraid of the prison life similar to the environment, so he fled under his own name.  
Three years later, he finally lost his way. After knowing the name of “passione” gang, he killed several cadres of rival gangs with his own special skills as a vote. After gaining the recognition of the organization and passing the trial of Polpo , he got the Stand “Metallica” and was assigned to the assassination team because of his own characteristics.  
Because of his appreciate to the gang that saved him, Risotto has always worked hard, done all the dirty work, and finally emerged as the leader of the assassination team. Even in the gang career, Risotto still has a weak sense of existence, but his decisive killing methods and efficient torture ability also convince other members, and also take good care of the members in daily life, which makes him deeply trusted and welcomed by the members. In addition, in the decision-making of team matters, Risotto often shows a certain momentum of self-control in key events, which makes the members to obey his decision involuntarily, but facts also prove that Risotto’s decision is almost the most reasonable.  
He has absolute trust in all the members. Maybe because of the influence of childhood , Risotto is very tolerant to the fledgling rookies, but he also has a way to deal with “rebellious teenagers”.
