(y/n) POV

The house has been filled with the constant sounds of blood-curdling screams of pain. My mother would return from the basement covered in blood and sweat. "She's just as sweet as I remember." Mommy said as she wiped her lips with her thumb before going to the kitchen to drink some water. I decided to go see what she was doing down there. "Kill me." a woman said as I walked downstairs and saw her.

I sprinted back upstairs. "Oh my did you find mommy's little toy?" Mommy said, "W-Why is saber in our basement?! Mommy, she's going to hurt us!" I cried, "Oh don't you worry. She couldn't lay a finger on us even if she wanted to, I made sure of that." she said, "I'll trust you." I said.

Mommy took me out on a walk, we were going to get lunch and then we were going to the park. But as we walked, everything felt cold; all I could hear was my heartbeat. Then I saw the man in the mask and my blood ran cold.

"You have seen me. You shall not live to tell others of this discovery." he said his voice was whispy and soft like he was whispering in my ear, but simultaneously it sounded distant and distorted. Suddenly his hand appeared in front of my face, I instinctually fortified my body and slapped away his hand. My heart was racing one false move and I'd die! When the man sprinted at me he drew a dagger and prepared to stab me, but I narrowly dodged and punched him in the chin, he looked back at me his neck cracking as he turned his head, "Oh fuck." I said as he thrust his wrapped arm at me, my heartbeat was defending. Every fiber of my being was screaming at me to run, but I knew if I did then he'd kill me! "Don't try it, Assassin." a man said as he grabbed Assassin's wrist.

"Run along child, and don't look back." he said I was terrified but I ran back to Mommy. "Hey, where did you go? What happened? You're trembling." Mommy said my vision blurred and the world faded into the background, I puked and then I just shut down.

Rider POV

I transformed into my servant form and drew my swords. The air was dead calm and neither of us moved a muscle, a bystander dropped a coin as he walked past us, and when it hit the ground we lunged forth. Assassin stabbed at me repeatedly, but I blocked with the blade in my left hand and attacked with the blade in my right alternating my attacking blade every third attack, and then every fifth attack after that. We were moving faster than the normal human eye could follow. When Assassin realized he couldn't breach my defenses he ran. He took to the streets, but I summoned my horse and gave chase. I slammed my blades together at the pommel and made a stringless bow, Assassin threw knives at me from atop a car, I took a breath and shot each knife with an arrow of light. I stood up on my horse and jumped at Assassin slashing at him, but he dodged only allowing me to cut the wrapping on his arm. "BUT THAT'S!" I said as he began to laugh reaching out to me, I jumped away and ran away, but he followed and we ended up at a construction site. "Human souls are insubstantial things. Writhe in agony!" Assassin laughed as his right arm extended into the air and lunged toward me, "AGIS!" I shouted hoping to block with my divine armor, " Zabaniya!" Assassin said as he touched my chest just a brief moment before my armor formed, "You've failed! Now face my Noble Phantasm!" I said, "TROIA HIPPO-" I said before my chest felt heavy, "You lose." Assassin said as he held my heart in his left hand before he crushed it.

Just because I love this version of Assassin from Heaven's Feel, here's a song about him.
