Kuroi Novachrono was an eight-year-old boy with, dark tan skin, who was walking down the road of his village trying to make it to his friend Nekro's house as he greeted some of the villagers who saw him before an elderly man called out to him.

"Kuroi, going to see Nekro?" He asked him as he nodded "Yup, we're supposed to go see his cousin Kanami and hang out," Kuroi said as the elderly man handed him a slip of paper "Take this to him, apparently it's from his father," He said as Kuroi took the paper and waved before continuing his walk.

(Nekro's House)

Kuroi made it as he knocked on the door and saw someone open it as he smiled, "Hey Nekro!" He said as Nekro smiled back "Hey, what took you so long?" He asked as Kuroi handed him the slip of paper "Apparently this is from your father," He said before seeing Nekro snatch the paper and rip it. "Why'd you do that?" "He wasn't around so anything from him I could care less."

Nekro then wrapped his arm around his shoulder, "Anyway, you ready to go see Kanami?" He asked as Kuroi nodded before they walked out to the back of the house seeing a girl with light blue hair and a pink kimono sitting on a bench next to a river as she turned around and smiled. "Hey guys," She said as they both sat next to her "Hey Kanami, how are you?" Kuroi asked, "Everything's going okay, my mother just had another baby and it's a boy," She said as Nekro tilted his head "What did she decide to name him?"

Kanami shrugged a bit, "She hasn't decided on a name but I suggested Eiji," She said as Kuroi stood up. "Well let's do what we're supposed to do," He said as they both nodded and stood up as well.

(Night)

Kuroi woke up in the middle of the night hearing something in the other room as he got up and slowly opened the door, "Anyone there?" He called out before hearing a scream as he looked inside before freezing as he saw Nekro's decapitated head on the ground with a fearful expression on his face before looking up and saw Kanami's body split in half with the same look on her face before running out of the building hearing everyone screaming and fire everywhere.

"I have to make it home," He said to himself before running in the direction of his house passing by people who were trying to either survive or look for their loved ones, he managed to make it to his house but saw that everything was fire and heard his mother scream. "Mom!" He quickly ran in ignoring the fire as he ran into his parents room seeing his father's burning corpse and a man in a suit holding his mother in the air by her throat.

"Let her go!" Kuroi yelled out as the man glanced at him before flicking his wrist snapping her neck and dropped her body "Who are you to give me demands?" He said as Kuroi charged at him before getting an arm wrapped around his throat "Brother, why do you have to mess with children?" A female voiced asked as the man chuckled "The way they react is interesting," He answered before Kuroi felt the arm around his throat tighten.

"This boy might be strong enough to serve sister," The man said as the woman looked down at Kuroi, "Maybe, but we need to see if he can withstand our blood." She said before pushing her finger into his neck and injected her blood into him before dropping him on the ground seeing him squirm around before stop moving.

Kuroi whimpered before looking at the man and woman as he clenched his fists, "I...will....kill...every last....one..of....you...even if...it...kills me." He said before losing consciousness. "Well boy, I welcome it." The man said as he walked off before the woman kneeled down and rubbed his head "I hope you give us a challenge," She said before walking off as well.

Kuroi Novachrono, once a human now turned demon has set off on a journey to get vengeance for the people in his village, his friends, and his family even if he dies.
