The world was incinerated. The last remnants of humanity remained to fight back, but they need help, perhaps, an otherworldly one. He is The Strongest Man of another world, a Paladin of Justice, where he is from, his mere presence comforts the masses and silences their cries. He is the strongest, greatest hero of his world, and his name is King.

A different hero was born in that one fateful fire. Between the Magi, Monsters, and other crazy magical phenomenon, can a Hero of Justice (for a hobby) prevail against them all?

The Kaleidescope is full of tales of heroism, that end with long, grueling, well-earned victories as fate demands it. So then... what of battles that end in one punch? The timeline diverges, with Alaya and Gaia unable to act as the world changes from one of mystics to one with magecraft and monsters. Heroes and monsters shall rise on both sides to save or destroy as fate demands.

Gilgamesh is NOT amused. Tokiomi needs to sit down. Kirei...is Kirei.

What if instead of being rescued by Kiritsugu. Shirou was saved by a bald man who wore a heroic cape... Fate was an unexcepted thing. Archer thought to himself.

Rin summoned definitely not Shiro. And whole Holy Grail War become broken… Translated from Russian.

A Fate/Stay Night & One Punch Man Xover story which is born from the idea after I have read One Punch Shirou by Sir Godot. I have thought for the summary yet, maybe in the future... Read and tell me what do you think! :)

What if the Berserker Illya summoned was not a hero from Greek mythology but a man who became a hero as hobby. OP!Servant
