A hero of justice [My hero academia x Shirou Emiya]

King Slayer

[PLEASE PLAY THE MUSIC]

"You were meant to protect the world not destroy it!" Shirou got in a combat stance as his hero outfit flew in the wind. "Don't you see Shirou? That's exactly what I'm doing, protecting the world." Artoria stood, hand on her sword pommel. "Then you are truly lost!"

Trace On
The two married blades were born in his hands, their sharp edges reminded him of himself.
"Why... why you... I'm right. To create a beautiful world the filth must be erased." Artoria reminded herself of the reason she fought and drew Caliburn.

In an instant they burst forward, Shirou reinforced his blades and struck her head. "To the left!" The voice of Emiya rang out in his head as Shirou twisted his body causing her powerful strike to barely miss. Shirou quickly threw the married swords towards her head while he was jumping to the left. "Give up Shirou!" She easily moved her head out the way to dodge the obvious throw.

This was Shirou's plan, however...
"Use it, now!" Emiya's voice commanded his actions as he sprang forwards.

I am the bone of my sword...
Not a man but a sword, not to think, but rather simply a tool to be wielded.

As strong as the tallest mountains...
The endless peaks he has climbed to get to this moment, every person he's saved, every man he fought. All for this single point.

Yet as graceful as the lonely river...
A single path lay in front of him, his ideals becoming the only goal that remains.

Trace on!
Two married swords flung themselves around the air and towards Artoria, jumping back she barely avoids the strikes.

This is our dream! I shall lift the endless heavens!
Not his dream alone but one he shares, not only with the spirit that commanded but the sheath that protected. The man in black smiled, his crest upon Shirous arm had found its place.

Over-edge!
As she witness Shirou jumping toward her Artoria realized something. She might actually lose?!

Triple Crane Wing!

The blades, as if they were lost in a typhoon, begin to circle in on her. Cutting through her armour they come from every side leaving no option of retreat. Finally, Shirou himself reached her, swinging Kanshou and Bakuya overedge in a large arc he's about to cut her head off. Then he remembered... the times they've shared... for less than a split second Shirou hesitates.

But this was enough.

In an instant Caliburn had pierced his body. "You hesitated..." Artoria was happy, to her this proved something. That Shirou loved her! 'Someone else must be making him do this.' She thought as she raised Shirous body into the air, sword still piercing straight through him.

"Why did you hesitate!?" Emiya was angered by Shirous actions. Yet he cannot say he didn't expect it, his younger self still lacked the conviction required to kill after all.

Trace on...

Despite being impaled Shirou couldn't surrender. He had something to fight for. Shinzō formed in his hand. A simple weapon made of bamboo, it possesses the wisdom of a legendary swordsman. Quickly swiping it towards Artoria's head, she is forced to flick her sword sending Shirou flying off the end.

Despite his injuries, despite his immense rage. He emptied his mind. Closing his eyes he no longer relied on his eyes to see. Rather he rose his sword into a simple kendo stance. Focusing on the future sight granted by the blade. He saw it, every movement she could make. Suddenly he stepped back letting an over-zealous strike from the king fly past him.
