[Anime Crossover] The Terror of Being Ruled by a Split Personality

One day, due to a small mistake by the transmigration god, the personalities of various characters from the world of anime and manga were switched...

The future boss of the Vongola, nicknamed Good-for-Nothing Tsuna by his classmates: (blinks happily) "Oh, I just realized the roof of Namimori Middle School is a great place to kill myself."

Reborn, watching from the shadows: !!!

#Today's number one hitman is still stopping his student from trying out creative ways to kill himself#

The Red King from Shizume Town: (bristling) "Die!!!!!!!"

Scepter 4: "This is bad, Chief. The Red King's Dresden Slate deviation value has surged again. He's about to lose control!"

The Blue King, just back from seeing him: "..."

#Today's Red King is still dangerously close to dropping his sword#

The red-eyed, curly-haired genius: (picking his nose) "Old man, you want to take my eyes? Shisui, are my bright, dewy, bewitching eyes the kind of thing some random old geezer can just dig out? How shameless!"

Danzo: "..."

Itachi: "..."

#Even Itachi Uchiha thinks his best friend's sense of decency is a little off today#

One day, the original owners of those personalities arrived in their world.

Everyone: ?!!

#That was the day they remembered the terror of being ruled by split personalities#

Note: The personality swaps are only temporary. At first, the transmigration god conceals what is happening, so the other characters won't notice the personalities have changed. Later, they gradually figure it out.
