Tsunahime had already become Vongola Decima and was happily married to Reborn. At 18 years old she had given birth to her first born son, Giotto Ietsuna Sinclair/ Giotto Ietsuna di Vongola. At 23 years old she had given birth to her youngest child, Celeste Kiyohime Sinclair/ Celeste Kiyohime di Vongola.
While Giotto was to be the next Vongola Head, Celeste would be handling things on the legal side of their businesses.
All was going well until... the moon shattered and only a quarter of it was left and Celeste's inner chaos was cackling in glee as her intuition led her to the Class of 3-E.
Giotto a.k.a Vongola Primo had stepped down the title of the boss and moved to Japan with his five Guardians. They changed their name and had their own family. One day a strange man appeared and asked the former boss and his Guardians, "Do you want to see the future of Vongola?"
