The Dawn of A New Sky
(KHR x Akatsuki no Yona Crossover)
At the age of 30, Sawada Tsunayuki, also known as Vongola Decimo or Neo Vongola Primo, died due to an incurable disease. Her eyes close and she breathes for the last time. Expecting to have come to the afterlife, she opens her eyes only to find herself in a child's body - certainly not hers - and in a different place altogether.
