Tsuna might not fight Byakuran at all. Uni clearly stated that she was the only one to defeat him and Tsuna in the future was either dead or in the time machine. Well, in the manga he is already fighting him and almost half dead.. Byakuran is way to strong.. [SPOILER ALERT] you have been warned Tsuna does in fact defeat(more like pulverizes) Byakuran and in the latest release Tsuna and his Family have returned to past, also the future Tsuna never died he was put into a special state that gave his enemies the impression of him being dead, so that the Vongola or any of Byakuran's opponents could have an upper hand.
