He also has a strong sense of justice and actively pursuing of what he believes is right for the people, which is why he formed the Vongola Family. He is shown to be a calm and collected leader that cares for his friends and family and is willing to protect them from harm. Their Guardians are quite similar as well: Yamamoto, Hibari, Mukuro, Lambo, Gokudera, and Ryohei have already been shown to be very much like their predecessors in appearance, weapon of choice, and personality. Tsuna has repeatedly been shown to be very much like him, as they have the same weapon and techniques (including the Zero Point Breakthrough), similar appearances, and equally unorthodox Families (the First Family included kings, military men, rival Mafiosos, and religious people). He is the great-great-great grandfather of Tsuna. After his retirement, he moved to Japan and started a Family, making Tsuna his descendant. He is also the creator of the Zero Point Breakthrough.
Shoichi apparently runs back home, with the package, afterwards and has strange nightmares that he feels won't stop until he returns it.Giotto is the Founder of the Vongola Famiglia, and thus, its First Boss. However, Bianchi is 'not in the mood,' and attacks Tsuna with her poison cooking. Reborn blasts Tsuna with a Dying Will (Or Deathperation) Shot, and then a shot to both cheeks, or a 'Niramekko Shot,' causing his face to swell up, at which point young Irie passes out. Then, Lambo blasts himself with the Ten-Year Bazooka not three feet from Shoichi, Bianchi sees Teen Lambo and tries to kill him, but is a horrible shot with a gun, and actually grazes Shoichi. When Tsuna appears, his hopes go up because he's a normal person. Lambo again perks up, takes the grenades designated to him, and throws them at Reborn, who deflects the attacks, blowing Lambo up before Shoichi's eyes. He relays what he learned to his mom over the phone, but she has been replaced by his sister because his mom couldn't make sense of what he said and decided to go shopping. After Lambo passes out from his wound, Shoichi flees, forgetting to leave the package. At that moment Lambo wakes up, and attacks Reborn while still on Shoichi's shoulder, but the attack is once again deflected. When Reborn appears, looking nothing like Shoichi had imagined. He comments on this to his mother over his mother's cellphone and she says they must be foreign celebrities. When he first gets there, he sees Bianchi sunbathing. He carries both the package and Lambo back to the residence. Shoichi's mother and sister ask him to take the package back and comment that it should be a man's job to bring Lambo and it back to Reborn's place.
This package includes olive oil, wine, and a wad of bills, as well as a pack of 10 Year Bazooka ammo for Lambo. Shoichi's Family receives a package after Lambo is bazooka-ed into their apartment. In the anime, he is now a part of the Vongola Famiglia in helping to destroy Byakuran. Later, he was found out to be a Fake Ring Holder by Byakuran. After the Base was destroyed along with the cameras, Shoichi told Tsuna and the gang, which now included Chrome, Kusakabe, Lambo, I-Pin, and Hibari, that he was on their side, and that this was a setup by Future Tsuna along with Future Hibari. He was the reason why Tsuna, Lal, Gokudera, Yamamoto, and Future Ryohei went to the Melone Base so that they could take him out. He also was at first shown to be a fearful leader as the holder of the Sun Mare Ring. Not much is shown of him in the Past, but in the Future, Shoichi was shown to be in close contact with Byakuran, being watched everywhere he went. Because Lambo was bazooka-ed into Shoichi's Family apartment, the Bovino Famiglia sends him a package, excusing Lambo for any annoyance that he caused. I n the Past, Shoichi Irie is shown as a 15 year old boy who happens to meet Tsuna and his Family.
