♥♥♥ I love this! Hibari's was especially heartwarming, and the last scene, too. It makes perfect sense that the date would be special for them. The end of the Shimon Arc rendered some of it obsolete, but you worked well with what we had at the time. And Yamamoto's apparently yearly aches - very Frodo, that. XDD

I found your take on Hyper Dying Will interesting, though - I always interpreted it as being about concentration, since Tsuna is usually all over the place. If Hyper Intuition is basically hyper awareness, then poor Tsuna is constantly dealing with too much information, and my fanon is that HDW allows him to filter and process all that stuff better.
