Stranger's Handbook - Chapter 40: Zest, the Mentor

Shi Jin once read a book. It was supposed to be about satisfying the desire for vengeance.

The main character, also named Shi Jin, was the sixth son of his harem-novel-protagonist-like father. All was well—while his father was alive. But after his death, Shi Jin’s five elder half-brothers tormented him, eventually leading to his death. The protagonist was reborn, determined to take revenge, and… the novel was discontinued.

That day, Shi Jin almost spat blood and dropped the book into a shredder. The next day, he died in a car accident. Somehow, when he came to, he had transmigrated into a teenager, a youth also called Shi Jin.

There was only one problem. His father had just died. His older brothers were about to torment him…

Shi Jin: Let’s eliminate my brothers’ hatred, my goal is to keep my life!

And then I was through—

Normally, monster-type creatures don’t just pop up in some random place—let alone a human place—out of the blue, and without notice.
Yes, if we’re talking ‘normally’, monsters belong more to places like remote, hostile grounds: they ought to be from dark, nasty forests, old caves, or abandoned, ancient ruins.
As I said, it was only so long as we spoke of the usual deal, however. For better or worse, I wasn’t your regular mob.
So, forget about all the remote, uneasy places humans hardly go to—all the abandoned forests, caves, or dungeons I, a monster, should have been from—and picture a bright, lively family restaurant, in an oh-so-peaceful human village. A restaurant where people ate, chatted, and jested together, all having a good time, blissfully oblivious to the fact that, very soon, I would be cutting them all down.

By magic, a monster-type creature spawned in such a place. It was me.
So far, for the few seconds I had been living, it was quite the good life… I got to listen to a fantastic story being told and shared a cool moment with people.
However! Following an uncertain course of events, I happened to be put up against a wall, with a sword aimed at my chest, before I was mercilessly killed.

I, a unique monster, just spawned in that restaurant, with no clue regarding what was going on.
All I knew was that I wanted to live and survive.
Also, I knew I wasn’t your regular kind of monster.
Thankfully, I’d been granted unique abilities before I showed up.
That is how I managed to survive.

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.

It all started when the protagonist downloaded a game called “The Fool (Beta Version)”. Since then, his life has changed.

A simple text adventure game with no graphics, no music, only lines of text and countless options, but every option in the game will affect the player’s fate, because on the opposite side of the game is a real unknown world!

Players cannot enter the different world, nor can they see the scene of the different world. They can only experience what the game characters see and hear every step of the way in the different world through the form of text.

With the progress of the game, not only the rewards in the game can be realized in reality, but also various abnormal creatures in the game began to appear in reality.

Until one day, the game will be tested globally.

An era in which all people explore and hunt treasures in different worlds through “text adventures” is quietly unfolding!
