[Crossover] No One to Guide Me

When Reborn arrived in Namimori and rang the Sawada family's doorbell, he found a Tsunayoshi Sawada who had successfully become a hitman. His personality had been pretty much trained into shape, and his skills were nearly maxed out. --Katekyo Hitman Reborn, the end. Reborn never got to appear. Reborn: ... Damn it! Who stole my job?! Koro-sensei: Nufufufu~ ++ As stated above, this is a crossover between Katekyo Hitman Reborn and Assassination Classroom, and may include a few other series as well. It's the story of Tsunayoshi Sawada growing up under Koro-sensei's tutelage to become a legendary hitman, ahem, mafia boss. Even though his job was stolen, Reborn still gets a chance to appear. Really. The timeline is set after Koro-sensei's death, with the assassination storyline interspersed through flashbacks. The timeline has been adjusted. The entire Katekyo Hitman Reborn plot takes place when Tsunayoshi Sawada is in his second year of middle school.
