When the two sets of twins were younger, the demons attached themselves to the first set. They paid no mind to other two really. Here and there playing with them, but not for long. Even Yorichii stayed around Tanjuro more, teaching him the breathing styles. I mean it would make sense to pay more attention to the one they thought would be the new demon king.
Muzan however was different and paid attention all of his children the same amount.
When Thana was six she easily picked up a sword and swung it around, shocking the demons. She learned her first breath by the time she was six and a half and had four down by the time she was seven.
Demons paid attention to her know. At first she was uncomfortable, but son stopped caring about what people think. By the time Thana was nine she had all breathing styles down, and was making her own.
Yorichii was proud of her, he was proud of her even before picking up her sword, but just got into training his first son. Thana never saw that though. She thought he hated her. She never dared to tell a soul though. She stayed silent and in pain.
One late night Yorichii wandered to the training ground and spotted his daughter. He watched as crystals from education on the ground and spiked up impaling the target.
Yorichii smiled then frowned when he noticed the tears on Thana's face. Eyes glazed over with tears. He watched as she dropped her sword. With a sigh he got up and quickly made his way over to his young daughter, and hugged her.
Thana was stiff. Not realizing someone was there.
"I'm proud of you sweetie." Yorichii said with a small smile.
More tears ran down her face.
"Thana?" Yorichii asked not understanding why she's crying more now.
"What's wrong?"
"All I ever wanted was for you to not hate me" Thana said in between sods.
Yorichii frowns, and hugs her closer. "I never hated you."
The sobs soon turned into sniffles and her body went limp in his arms.
She was way to overworked, anyone can tell, just by looking at her. He carried her off to bed and tucked her in vowing to get closer to her, and of course he did.
