Two Sides of the Same Coin

The Brothers

The elder brother was named Baku, and carried his last name with pride. His power and abilities were strong and stayed close to his father. He was the eye that kept his father alerted if the upper moons had stepped out of line. He didn't enjoy it as much so he'd cause trouble here and there for more entertainment. He caries a smoke grey nichirin blade with him at all times to punish any demons stepping out of line. How he got a hand on the blade was a story in on its own.

He was born not only to his father being Muzan Kibutsuji, a demon king, but as well a son of a wealthy European woman. His mother was young when he was born. His appearance had changed since he turned into a demon. His memory of his mother was a blur. Baku didn't care much about his mother to know about her. He couldn't care much anyways since he was he one who killed her. He was cold and hated the idea of any idea of a mother. But on the other hand he cared for his dad extremely. He was his god. A lord to him.

The younger brother, was known as Daichi. His cold stare pierced through many things. He had made his own form of breathing, snow breathing. Which derived from wind and water. He was harsh and always refused the title of a pillar despite having the strength of one.  Though it took so much pressure from his adoptive parents he agreed. He was the snow Hashira.

He knew about his father and brother. He had Muzan's blood running through him. He was able to control his demon half keeping it to the back. He refused to snap and turn into something he hated. The thing that took his mother.
His hair had whitened due to his demon half. His hair used to be a charcoal black but when he had grown it turned white like his elder brother.

He was raised by his mother and Muzan till the age of 6. That's when the blood of his bloodline tried to over take him. Just like it did to his elder brother but his mother gave up for him. His mother had a special type of blood that'd not only give him strength but the will to resist becoming a full demon. Daichi's mother was fully aware her son wouldn't be able to resist when she made a cut for her son to drink.

The boy had snapped letting that side of him control him. Before he knew it he had weakened his mother too much. He remembered how his father turned other into demons and thought it was worth a try. He was son after all. It'd save his mother. Right? But the plan backfired. His mother couldn't take it and died. The poor kid cried for days. He couldn't believe what he had done. Soon after he was able to restrain his demon side.

He was more human but his white hair and icy eyes separated people from him. He wandered through forests and woods. That's where he found his adoptive parents. He was taken in by the couple of low ranking demon slayers. He was happy with his new family he wasn't isolated. It wasn't long after he turned 8 the family conceived a baby. Naming them Tsukki.

Despite how happy everything was, it was destined for brothers to fight to the death. To finish one another in the mass end of things. But they are yet to intertwine paths once again. They had been separated for 12 years and it wasn't likely to meet again. Well that's what Baku thought till the day his father met the boy with the hanafuda earrings. He knew that things where gonna get bad. That he'd have to deal with demon slayers again. And his little brother.

Daichi had met the boy with the hanafuda earrings when he had gone to slay demons with Giyuu. Daichi and Giyuu mutually saw each other as friends but refused to ever get close. They both had the same age and mutually caught feelings for each other. But they never made it official. The dark haired male still had feelings for the other but Daichi had married a year after encountering the boy.

Daichi now knew the boy as Tanjiro Kamado. A boy who wanted to help his demon sister. Daichi envied the closeness between Tanjiro and his demon sister. It enraged him to some points nearly revealing his demon side at multiple times. He had to restrain himself. He didn't want to be found out. Well by others who weren't the master. His family was close to his so it was obvious the master knew who he was. And of course his bloodline.
