Tsuna is not a ordinary child, no child can understand a cluster of languages or top tier math problems. From Mafia to Vigilante till death he will now rise up to be a hero worthy of the title.

"God, or whoever is up there... please give me another chance. A chance to redo everything, a chance to redeem myself. Please... I just want to see my family again." I just want to see my family happy and smiling again. I couldn't resist and met unending darkness . . . . Or that was what I thought. ♪( '▽｀) REWRITE of [KHR: Another parallel world?!] Disclaimer: KHR and BNHA/MHA does not belong to me.

This is a side story of Hero or Mafia. this will follow the omake part and will be rather short. This is only to tell about the festival I won't be able to put in the main story.

Sawada Tsunayoshi, Vongola Decimo , and his two friends infiltrate UA high school at first just to protect one Midoriya Izuku, as time went on their protection expanded to the teachers and Pro Heroes that helped Class 1-A. What they never intended to happen was to get so involved with the class that they began to help them build their character and their quirks furthering their path to be heroes. The sports festival was the first step to being part of the class even though the three Vongola's were three to four years older than the class themselves. They and the class went on to do internships where the Vongola began to recruit a student with the ability to mind control people. Shouto Todoroki, Shinso Hitoshi, and Tokoyami Fumikage accompany Tsunayoshi to Sicily where the three will be trained to better use their quirks and participate in the 100th-anniversary celebration of Vongola being a company. Following the internships were the final exams ending the first semester. With the most interesting test being first, hyper intuition vs a quirk that calculates every possible outcome. With the final exams done the class began preparing for their summer training camp where things become chaos when villains attack the camp kidnapping Bakugou Katsuki and Pro Hero Ragdoll from the Wild Wild Pussycats. By then the villains have an idea who they are messing with when the Vongola's move into action helping the heroes create a diversion so they can rescue Bakugou even though Kirishima Ejiro, Iida Tenya, Yayzoro Momo, and Izuku Midoriya do the rescuing so All Might can fight a villain dubbed as All for One. Tsuna and his Famiglia helped with rescuing and evacuating the civilians that were caught in the debris field. All Might won the fight and finally put All for One in prison, which also ended Vongola's mission.
