Sawada Tsunayoshi spent more than ten years as a good-for-nothing. Then one day, someone transmigrated into his body, and he found out that he was... the legendary protagonist?
The transmigrator not only took over his body, but also left him with a pile of trouble when they left: strange bloodlines, a System that keeps assigning bizarre missions, and two missing years.
Worse still, he's not the only one in this world who has been transmigrated...
This story features Katekyo Hitman Reborn!, The Disastrous Life of Saiki K., Detective Conan, Kuroko's Basketball, The Prince of Tennis, Yu Yu Hakusho, K, and more. Warning: elementary-school-level writing and a mishmash of styles. All OOC is on me.
The "I" in the title doesn't refer only to Tsuna, and "protagonist" doesn't mean the one and only lead of a single series. It means "main characters." I just thought two characters sounded better than four (x). So this is a story about the main characters from a bunch of anime getting transmigrated.
