Lal

How Lal joined the Tourney
Lal Mirch, in the future, comes off as a no-nonsense type of person. She outright tells Tsuna that he isn't progressing as fast as she'd hoped, and then gives up on him as a student. On an occasion before that, while instructing Tsuna and his Rain and Storm Guardians about Rings and Boxes, she attacked Tsuna and Yamamoto when she felt that she was losing their attention. Lal Mirch was to be the original holder of the blue pacifier for the Arcobaleno, but was unexpectedly replaced by Colonnello in his attempt to save her from the Arcobaleno curse. Due to Colonnello's late timing, Lal still had to carry half of the curse, being that she shared the same physical effects as the other Arcobaleno but was unable to attain the full power of the blue pacifier, which was given to Colonnello.

After the war in the future, Lal Mirch heads to the past to stop a rebellion. Lord Gohda and his forces would be participating in the Second Tourney, and one samurai woman is trying to assassinate him, Mifuyu Tadokoro.
