For a prompt on my Tumblr: TOS!Sannin. Tsunade McCoy the grumpy, compassionate alcoholic with a heart of gold, Jiraiya Kirk the cocky and intelligent leader and womaniser, and finally, S'chan T'gai Orochimaru, the 'non-emotional' genius scientist with a not-so-hidden soft, gooey emotional centre.

Tsuna and his guardians died in a blaze of glory. Then they woke up, slowly, one at a time, in a different world that was the same in all the ways that really mattered. Or the one where Tsuna and his guardians are reincarnated into the class below the Konoha rookie nine.
