Kyoukai Senjou no Horizon – Kimitoasamade - Volume 4A, Chapter 5: Warner on the Horizontalt

Born as a lowly goblin, Leav refused to accept fate’s cruelty. Through sheer will and tactical brilliance, he clawed his way up—evolving, battling, and commanding monsters who once saw him as nothing. But power comes at a cost. As war rages and enemies lurk in shadows, Leav faces betrayal, brutal losses, and the cold truth—strength alone won’t forge a kingdom. With ancient magic resurfacing and rival factions closing in, can he rise above mere survival and claim true dominion? In a world where the strong rule and the weak perish, Leav must choose: remain a pawn or become a king.

Suddenly appearing in a different world, it looks like I got caught up in a Hero Summoning. And of course, I’m not the Hero, but it’s another guy……and while being very cautious and scared of the cliche of the cliche-like development, I was thrown into the maelstrom of war……or not.

The Demon Lord? It was defeated a thousand years ago. Hero? He’s just the main actor in a festival. Nobles? They’re kindly taking care of us. The Demon Race? They have good relationships with Humans. Wars? It’s already 800 years since the last one. Monsters? The Guild and Order of Knight are taking care of them. Return to Earth? It is eventually No-Risk.

What I’m planning after being caught up into this? I’m gonna enjoy the life in a different world as much as I want to, go on a cultural exchange and sightseeing, and after experiencing the festival that is only held once every ten years……I shall go home safely.

The other world was――at Peace.

A kind world where the three races, the Spirit World’s Magical Races, the Celestial World’s Divine Races, the Mortal World’s Human Races, they are kind neighbors to each other, with everyone living a peaceful and fulfilling life.

But although I wished to peacefully spend a year before my return, for some reason, the heavyweights of this world keeps gathering around me, and……

Fate had never been kind to Ji Ning. Wracked by illnesses and infirm his entire life on Earth, Ji Ning knew early on that he would die as a teenager. What he didn’t know was that there really was such a thing as life after death and that the multiverse was a far larger place than he thought.

A lucky twist of fate meant that Ji Ning was reborn into a world of Immortals and monsters, of Ki Refiners and powerful Fiendgods, a world where Dynasties lasted for millions of years. A world which is both greater… and yet also smaller… than he ever could imagine. He would have the opportunity to join them, and in this life, Ji Ning swore to himself, he would never let himself be weak again! The Era he was born into was a Desolate one, but Ji Ning would make it his era.

A 29 year old civil employment exam student wakes up in a blank white room and meets a baby angel. This baby angel informs him that he died in his sleep due to heart disease like his father and grandfather. Remembering his mom and their last conversation he says that he will take on a series of life and death tests that the baby angel offers him. From this point on he must put his life on the line and fight in the stage called ‘Arena’. And Every time he clears a test he will gain abilities and weapons to increase his strength. All to clear the tests and get his life back. This is his story of his fights in the ‘Arena’.
