The Yokohama Assassin in the Vongola Family

Yi Shiyu is an assassin, student of Reborn, the world's strongest hitman, and a hedonist. He currently works for Yokohama Port Mafia. Reborn's assessment of him: "An elegant, beautiful, good kid. My finest student." Besides making money, he has two goals: One: sleep with Nakahara Chuuya, in the on-top position. Two: sleep with his teacher Reborn, in the on-the-bottom position. Recently, Reborn wrote to ask him to serve as substitute tutor to the Tenth Vongola boss for three months. Yi Shiyu hates timid, spineless guys, so he showed his junior no mercy... Three years later The Tenth Vongola boss, now a perfect leader, finally caught up with the substitute tutor who'd had his fun and run off. "Senior, thank you for taking such good care of me back then." Yi Shiyu: "...You can talk without pinning me down, you know." Also known as "The Corruption of a Soft, Adorable Bunny," because he'll be put through the wringer. 1. Pairing: Tsuna is the top (you read that right) x Yi Shiyu (original protagonist, bottom). They first meet when Tsuna is 16 and Shiyu is 22. One-on-one, happy ending. 2. Dynamic: a timid, scheming top who turns dark later on x a hedonistic assassin boss on the bottom. Occasional cross-dressing, younger top and older bottom, lots of headcanon. 3. The bottom is an adult and an assassin, and a very good student of the demon king. His nasty personality is no joke, so read with caution! If you click in, that means you've accepted the premise =w= But the story is lighthearted, so don't worry. 4.
