After Becoming a Little Sun, I Transmigrated Again

After becoming the Little Sun, Karna reenacted his life as he knew it from history, and successfully entered the Throne of Heroes after his death.

While wandering around his garden on the Throne of Heroes out of sheer boredom, Karna was approached by a System, which demanded that he save the original plots of works that had been ruined by transmigrators.

Karna: "?" What did that have to do with him?

System: "QAQ, you're one of the few transmigrators who don't mess up the plot! Think about it. If the fates of the original characters suddenly changed, would the characters you love still be the same people?"

The System coaxed him patiently. "There must be a male character you adore in your favorite anime. If he hadn't been shaped by all those events, would he still be the same person? Huh?"

Karna: "...Oh."

The System broke down. "Sir, I know divinity has made you indifferent to all this, but we have to protect those worlds, or they'll collapse!"

Karna: "And then?"

System: "Then everyone except me and the other Systems will lose all memory of those works, and they'll be replaced with memories of other anime!"

Karna: "What does that have to do with me?"

System: "QAQ!"

Karna: "What's in it for me?"

System: "You can bring back the items you acquire in those worlds to the Throne of Heroes!"

Karna: "...That's it?"

System: "QAQ, we can't take you away from the Throne of Heroes. The current you is a projection of your original self, and when you return, you'll become a new individual."

Karna: "..."

System: "Well?"

Karna: "Make sure there's enough mana."

System: "No problem!"
