Reborn! - The Boss's Diary

This is a diary written during his school days by the current first godfather of the underworld. The story of Tsunayoshi Sawada, head of the Vongola family, before he grew up. This hefty diary clearly records Tsunayoshi Sawada's (tragic) history of growing up. Its contents are full of experiences like those in a shonen magazine (JQ). Let's open up Diary-kun and look back together at the boyhood years of the boy once known as Useless Tsuna!
