A crossover between KHR and BNHA. Tsuna has been drowning in work lately and thus Reborn decided to spice things up a little. Asking a favor from a certain someone, he managed to arrange a class field trip to the most prestigious school in Japan; U.A Academy, where Heroes are made. Just what could happen when mafia meets heroes? Hopefully, this trip will teach the Vongola on what it means to be a hero. <~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~> Disclaimer: I do not own KHR or BNHA. All credits belongs to Akira Amano and Kohei Horikoshi respectively. Also, Pics used does not belong to me. But the plot belongs to me!! Warning: Grammar mistakes This is my first try at writing a crossover so I hope you enjoy. 1 June 2018~ ongoing

Tsuna finds himself in a world full of weird looking people. It's either someone is shooting fireballs out of their mouths, having wings on their backs, lifting super heavy objects, or etc. Now, he needs to fulfill his parallel self's promise to his mother. But it looks like his father had different plans for him.

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.

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.

Tsunayoshi the Vangola Decimo has passed away due to old age and was left to peace leaving the Vangola to his children and being a great man. Or so he thought but apparently fate wanted him to do more by being reborned into the oushitsu kyoushi Haine world as the second prince Xavier Von Granzreich
