My Superpower Is Rebooting the World

A little introduction: my name is Shen Qiandai. I live in Yokohama and I'm an ordinary high school student at Rikkai. My supernatural ability is World Reboot. Its passive form activates when I die an unnatural death, turning back time to before I was born. Its active form lets me control the timeline, including but not limited to stopping time, rewinding time, and speeding it up.

In short, I'm a god who controls the timeline. Very chuuni, I know.

I only like beating games in one life, so I've never used my ability.

That is, until I started high school.

Now, I'm in my third first year of high school.

If I ever find out which bastard keeps twisting the timeline, I'll bury them alive with all the homework I've done over and over during these three years!

Dazai Osamu, the ultimate ability-canceling bug, clearly remembers that his best friend has died three times.

Will this attempt be useless too?

Save him, and then return to the starting point.

Don't save him, or this may be the final loop, and he will have to watch him die before his eyes.

The numb coward doesn't dare to gamble, and secretly searches for the cause of the time loop.

Kusuo Saiki, who knows nothing about this, sneezes. Is someone thinking about me?

When will this about-to-erupt volcano finally be dealt with? What a pain.

The main story is written in third person.

A crossover with The Disastrous Life of Saiki K., Detective Conan, whose timeline is just as tangled, and Yokohama, where supernatural abilities run wild.
