High Martial: I Became a God by Writing a Diary

I transmigrated to a high-martial world and awakened an F-rank good-for-nothing ability. The whole school laughed at me.

That was until I opened the diary my father left behind.

[Whatever you write will come true.]

Today I wrote: “The school bully gets on his knees and apologizes.” He really did.

Tomorrow I wrote: “My ability jumps straight to D-rank.” The testing device really lit up.

Then I got carried away and wrote: “I kill an SSS-rank demon with one slap.”

The whole world thought I was crazy.

Until a rift opened in the abyss and an SSS-rank demon descended.

Everyone looked at me.

I looked at my palm.

“How about… I run first?”
