My Cheat Is the Genshin Impact System

[Screenshot dated January 11, 2023]

Hanemiya Rei was an ordinary office worker. After getting into a car accident, he was reborn with the game he'd spent day and night grinding and paying through the nose to play!

Having a cheat ability was great, of course. At least his personal safety was guaranteed, right? But how should he put it?

Not only was the selection of characters granted by the System extremely limited, but at the start he could unlock only one basic character! It was basically like starting from scratch.

And to get more characters, he had to travel to other worlds and complete limited-time missions.

Hanemiya Rei looked at his post-rebirth body, which could be killed with a single punch, and was overcome with deep anxiety about the future.

To complete his missions, he kicked the bucket, clutched the script in one hand and his secret identities in the other, and helped the Demon Slayer Corps wipe out demons. Before he knew it, he'd won over a bunch of the members (?).

Something felt off, but he cheerfully kept completing missions anyway. He prevented a friendship from falling apart and casually dealt with a brain-shaped thing that looked utterly disgusting. But when the mission ended, everyone around him looked like they had something to say but couldn't bring themselves to say it.

Hanemiya Rei: Why the black face and question mark?

Now that his personal safety was guaranteed, he decided to move away from dangerous Yokohama. He had a bright future ahead of him! He was going to school!

But why did his deskmate look so familiar? Wasn't he some kind of Vongola boss?

Things to know before reading:

① The timeline has been altered in several places, with lots of authorial additions. OOC warning.

② A feel-good power fantasy, no pairings in the end, friendship with Konoha! Absolutely true! Read with caution if that's not your thing.

③ The worlds may merge later on.

④ I'll add more if anything else comes up.

Theme: I'll think of one later.
