[Crossover: Reborn!] Reversing Impressions

I got halfway through the extra chapter and got stuck, trying to figure out where to take it next. Then I... came up with another idea.

The System said, "Come with me and save the world."

The System said, "I'll find a good replacement for you."

The System said, "Don't worry."

Fourteen-year-old Tsunayoshi Sawada innocently believed it and followed the System to save another world. After crossing countless worlds and returning with the title of Savior, what awaited him was...

A greedy, ignorant Tenth Boss of the Vongola, Tsunayoshi Sawada, brimming with pointless arrogance and loathsome avarice, shamelessly trying to add his Guardians, the Varia, allied families, and even his enemies to his harem.

Tsunayoshi Sawada: ...

The System had never expected things to turn out this way. It could only put on a mournful face and stammer, "W-why don't you try raising their affection for you? Your career achievements are already maxed out in all the other worlds, anyway. QAQ"

Just think of it as saving one last world. TAT

The System pleaded tearfully.

Sitting on a soft sofa and staring at the luxurious, unfamiliar bedroom, the Savior groaned in pain and covered his youthful face, so carefully tended to by the replacement.

Maxed-out combat power. √

Maxed-out charm. √

World-saving achievements x N. √

Maybe old friends from other worlds will come by to have a look (mock)
