Owari no Chronicle - Volume 12, Chapter 18: Riddling Moebius

While on a school field trip in the Czech Republic, Kang Hyuk happens to stumble into a shop called “Archmage.” To his disbelief, the shop is actually owned by an archmage… from another world! Forced to become the Archmage’s disciple, Kang Hyuk is punted into the Kallian Continent, where might and magic overwhelm and wyverns fly high in the sky…

In this world, people are either sword-wielding knights, magic-wielding mages, or spirit-wielding summoners. There hasn’t been anyone yet who can do all three… until now.

The plague of insects descended overnight. As an ordinary person without invincible powers and extraordinary exercises, facing blood and death, what should we do at the critical moment of life and death?

(I am a reasonable party, but the novel needs appropriate YY, please do not excessively investigate the rationality of the background in a razor-sharp way.)

- Description from novelbuddy

In a world of countless enemies, the right talent is all it takes to thrive. Freddy Stern, a twenty-one-year-old cashier, has lived a plain, albeit harsh life. Having been orphaned—twice—he’s spent the last ten years working and staying out of trouble. His only aspiration is to save enough money to become an archhuman. His dream gets the jump on him when he barely survives a near-death encounter and finds himself with 1% Lifesteal, a bizarre talent with numerous contradictions and just as many uses. With every dead enemy, he becomes a bit stronger, a little wiser, and a lot more ruthless. And no matter how much damage he takes, he can always put himself back together. Physically, at least. But on his path to power, after having to look at the rotting guts of archhuman society again and again, can his talent keep his mind and soul as pristine as his body? Or will that part of him simply remain broken?
