[ The Passive Skill ‘Consciousness’ has been acquired! ]

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.

5 years after the world changed, the final boss appeared.

The past life Ji Anran: “Geng Yan, let’s get back together.”

Geng Yan, who was dumped: “I refuse. You have powers anyway, and you can live well without me.”

After rebirth, the weak chicken Ji Anran: “Geng Yan, let’s get back together.”

The dumped Geng Yan: “I refuse.”

Ji Anran, lying dead: “I have no power, you don’t care about me, just let me get cold1.”

Geng Yan: “… …” The unsuccessful Geng Yan can only take away the weak chicken, one cannot put sand on the wall2 Ji Anran.

Later… what about the ordinary person without the strength to truss a chicken?! Who’s the guy in the day?
