Prologue : The Day My Nightmare Came True

What is the sky without its elements? Without the storm, rain, mist, cloud, thunder and sun; what is the sky without them? Nothing. "Where are your guardians, Vongola Decimo?" "Decimo? Am I still the Vongola Decimo?" A story that features what would happen if Tsuna was without his guardians. Inspired by many Abandon!Tsuna fanfics. There would be some OC, but not so much. Hope you enjoy desu~!
