|The Secret Base|
|Volume||Ten Years Later|
Suddenly, Future Yamamoto appears and stops the Strau Mosca with Attacco di Squalo. Tsuna and Gokudera are surprised at Yamamoto's appearance. Yamamoto wonders if their presence was a joke or an illusion. Tsuna explains why they are there, and Yamamoto simply tells Tsuna that many things have changed the past ten years.
Yamamoto shows them the location of a secret Vongola base. Lal Mirch falls unconscious as soon as she walks in for an unknown reason. Inside, they find Reborn much to Tsuna's surprise, shock, and relief. Reborn reveals they only went nine years and ten months into the Future, rather than the normal 10 years, along with the fact that they were still in Namimori. Yamamoto also adds that Future Tsuna was dead. Gokudera punches Yamamoto in anger for letting Future Tsuna die. Yamamoto revealed that there was also a "Vongola Hunt" going on, where the Millefiore Famiglia hunts down every Vongola member as well as their families and friends; Yamamoto explains that his father had been killed and that the Tomaso Famiglia, Tsuna's mom and dad, and Mochida had gone missing as well.
