Sanctuary Night (Kaitou Kid X OC)

Chapter 1

 "Father... I... I can't...!" Said a young girl breathing heavily as she went through a rigorous training from Ryo Kuro, master assassin. Her father gently approached her and laid a hand on her shoulder.

"You can do this, my daughter... I know you can. Just a few more and we'll be up on the summit." Ryo softly said, pointing upwards at the top of the mountain. 

----

Father and daughter, Ryo and Rie Kuro belong to a long chain of assassins. They do not kill for the money nor the fame. Their hearts belong to killings of justice. Corrupt politicians, undignified criminals and ruthless clans of other assassins - those were their usual targets. Trained at a young age, reaching the standards of an expert by the time of puberty. Contrary to most assumptions, taking another's life is their clan's last resort for victory. Kidnappings and mental tortures were all it took for their targets to confess to their crimes. The confession will then be set out to the public and the captured will be freed. All this is done in silence. All this, done by one clan. A clan called 'Sanctuary Night'.

Rie couldn't take another step and finally dropped down to the ground, desperately taking in air. Her father sighed and sat down next to her, pulling out a towel before tending to his daughter.

"You did well today, Rie-chan. You climbed up more than yesterday!" He happily said, wiping off her sweat as she smiled weakly at him. He took hold of her, carrying her on his back and jumped up onto the highest branch of the nearest tree. He set her down next to him as she finally caught her breath.

"Look at the night sky, Rie-chan... Isn't it beautiful?" He asked in a lulling voice. The little girl nodded in reply as she took in the sight of a million twinkling stars above her. 

"The night is endless. It may be stopped by the day, but it will not end." The man said, pulling his daughter close. "You are just like the night, my dear Rie." Her dark indigo eyes quickly looked away from the sky and straight on to her father's. She blinked twice, not understanding what her father just said.

'Father and his mumbo jumbo again...' The girl thought, her eyes not wavering from its gaze.

"Tonight, you may have stopped here, but tomorrow, as a new night arrives, you will go further. Further and further until you reach the top. There, you will find a new goal, then, the night will continue on." He finished as he took hold of his daughter once more onto his back and dropped down.

"Race you back home, Rie-chan! Look out for the vines this time, okay?" Before the girl was even able to respond, her father vanished. She quietly giggled and followed suit, running almost as fast as her father was. 

Rie arrived home, greeted by her grinning father and smiling mother. 

"I'm home!" She cheerfully said, running into their embrace. 

"Welcome back, sweetheart. I see that your father stubbornly challenged you to a race again, huh?" Fusae, her mother, joked. The girl pretended to pout as she nodded, pointing an accusing finger at her father. The culprit raised his hands in surrender.

"H-hey, I still get my curry, don't I?" He pleaded. Rie tugged on her mother's dress while shaking her head no. Fusae giggled at her daughter's antics and tapped the other end of the serving spoon on Ryo's head.

"That's for not letting Rie-chan win. And this," she used the same spoon and added more curry to Rie's plate, "is for not apologizing."

The happy child leaped off of her mother's lap and started to eat, thinking her father might take it away.

"W-what!? But she doesn't even like curry!" Ryo protested to which Fusae replied with taking his whole plate away. "N-no, I take it back!" He continued, trying to grab his plate that was put on the other side of the table. Suddenly, an outburst was heard. The couple looked over to their child only to see her fanning her hand over mouth which was full of hot food. Ryo handed her a glass of water which she gladly took. After doing a bottoms up, the poor girl looked up to her parents bashfully.

The family of three laughed as they continued to have their dinner. 

But then everything changed with a flick of a wrist.

Suddenly, the little girl and her mother were terrified as they hid together in the closet as the man they've come to love fought a dreadful enemy right outside the closet door. Rie sobbed as quietly as she can and clung to her mother tightly while Fusae desperately tried to cover her daughter's ears. The horrified girl was seeing all of the tragic events unfolding from the tiny crack behind the door of their hiding place.

Ryo was up against a man in a dark suit with a matching black fedora. The only notable feature about him was his horseshoe mustache. The man had Ryo at gunpoint, but the Sanctuary Night was faster than the bullets. He had the choice to dodge them, to deflect them or to cut them. That was the prowess of a master assassin. 

Swear words were thrown back and forth between Ryo and the black suited man. 

"I'll never tell you where it is! You won't get the information from my family either, they're off the mountain by now! Leave my house right this instant, you no-good, thieving bastard!" Ryo pulled out another knife and held it firmly as he threatened the invader with it. The suited man merely chuckled.

"Your stubbornness has always been your flaw, legendary Sanctuary Night." The enemy growled in a raspy voice but Rie's father remained unfazed.

"A flaw I choose to embrace!" Ryo roared as he used the last of his strength and charged again, making a clean cut on the intruder's left forearm. The assassin was utterly weakened, trying all his might to get up and create distance between him and his assailant. The man only winced in pain and shakily held up his gun.

"This was your last chance. Go into your blasted sanctuary within the night, scum." A gunshot was heard. Then another. Then, a thud. Then finally, silence. Heart wrenching silence echoed throughout the quaint living room, only faint cries were heard. 
 
The invaders left, the Kuro household was turned upside down, and the man of the house was long gone.

Then, she sprang awake.
