The world has been incinerated. The last remnants of humanity are on their last legs, unable to fight against those who wish to see them annihilated. To aid them, one man will cross even the boundary between worlds. A Paladin of Justice, a man whose mere presence comforts the masses and silences their cries. He is King, The Strongest Hero.

Kirie Kotomine was supposed to summon Assassin, Hassan of a Hundred Faces to be precise. He failed spectacularly. With years of planning down the drain, the Masters and Servants of the Fourth Holy Grail War must scramble to deal with the unique replacement to Assassin, the Bald Hero for Fun and Profit, Saitama. Gilgamesh is NOT amused. Tokiomi needs to sit down. Kirei...is Kirei.

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?

As Saitama walked back to his apartment after defeating a monster with just one punch. He encounters a young girl lying on the streets. Rather than leave her there, he takes her back to his apartment and becomes his neighbor next door. How will she fare up with this life? Find out as she handles from Rampaging Monster to Eccentric Heroes. (Completed For Now)

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.

Illyasviel von Einzbern did manage to summon a Berserker, but this servant was painfully stubborn and loved to do things with its own way. Soon however, she would learn the reason behind its deviance and its extreme hatred towards other servants.

¿Una nueva guerra por el Santo Grial? o ¿Una Singularidad?

King. Humanity's Strongest Man. Known to all, loved by all, sung by all. But WE know that is not the case. Or IS it? Will the man with the strongest luck and misunderstanding have a chance to showcase his "Strength" to everyone? A chance encounter will decide what will happen next.

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

[One-Shot] x [One-Shot] Shirou Emiya - an ordinary boy who wants to be a hero. And to be a hero, one needs to be strong enough to save the people in need.

[FSN x One Punch-Man Crossover]
