This is the product of reading a certain article that tortured Skylark.
I don't think that's fair to Skylark.
Therefore, I plan to torture Tsuna~~
Hee hee, that article is "Nian Duo Duo Duo Shao"
In order to save himself and Tsunayoshi from the pain, Hibari Kyouya decided to use Vongola's vertical space-time miracle axis to go back seven years ago and exchange himself for the late Arashi Mamoru. However, although he was not dead, he did not return to Vongola. From then on, the Discipline Committee and the Discipline Foundation disappeared with him... Where will Hibari Tsunayoshi go in the end? What price did Skylark pay for using the Vongola vertical space-time miracle axis?
