Revealed Truth is the 136th episode of the Katekyo Hitman Reborn! anime.
Shoichi tranquilizes the Cervello before they can kill Tsuna's friends. He reveals that he is on the Vongola's side, and that all the events that have occurred was a plan devised by Shoichi along with future Tsuna and future Hibari in order to train their past selves to defeat Byakuran. Shoichi reveals that the next step of the plan will depend on the Millefiore base invasion in Italy, which is led by the Varia.
