The parallel world of Bones is imaginary and warm.
The parallel axis of the world set by the tutor is very far away. Vongola was cleared as early as the eighth life, and the biggest boss in Italy was Simon who came out early (I guess the text is soy sauce).
Estoranio was also destroyed, but Mu and others were not used as experiments. Under Simon's high-pressure attack, Mu and others were entrusted to Vongola and sent to Japan.
His current identity is a newcomer secretly trained by Vongola's film and television group.
Tsunayoshi... Is still a loser no matter where he is.
