[Katekyo Hitman Reborn!/Sakamoto X Hibari] The Tenth Boss Is Forced to Play the World's Strongest Assassin

The strongest □□ godfather, the finest graduate of the JCC Assassination Department, the Kill League's strongest former Order member, a fugitive with a bounty of a hundred billion on his head: a truly astonishing life.

If this person weren't me.

If I weren't Tsuna from ten years ago.

Master Sawada, who defected more than a year ago, has returned.

The students at JCC watch the newly returned Master Sawada.

In practical training, he calmly picks up a pistol and misses every shot.

In the Intelligence Department, he calmly jumbles every clue together.

In the Poisoning Department, he calmly tosses chemicals into a flask, never looking back at the explosion.

Just as everyone begins to wonder whether this Master Sawada is actually some random person Nan Yun found and disguised as him to control the others,

Master Sawada beats them all black and blue in hand-to-hand combat.

Yep, that's the right flavor. This is definitely Master Sawada.

Realizing he can't go back, Tsunayoshi looks at the Vongola journal, the Kill League manual, and the organization's survival guide in his hands, and is suddenly thrown into a life of spy within a spy within a spy.

With help from a disguise expert, he diligently plays the role of his future self for ten years.

He survives countless assassination attempts and clears himself of suspicions that he's a spy in both organizations. Just as he thinks he can finally go home in peace,

his home tutor finally catches up to him on this timeline and kicks him back to JCC:

"The Vongola heir can't be this embarrassing. Graduate with top marks, and do it with the resolve to die!"

TIPS:

CP 6927. It's just a story about 27 doing his best to play 270. That's more or less the premise. Apart from the Katekyo Hitman Reborn! and Sakamoto Days elements, everything else is subject to change. I may add more before I start writing, and if the original work has any major spoilers during the pre-release period, I'll make big changes.

In short, it's another pot of stew made by throwing all the things I like together...

69 is a ghostly presence: not there, yet somehow there.

Theme: Everyone has to do their part to protect world peace
