The Earth Bound dragons.

Chapter 1

Suiryu was smiling from a distance. Since after all, his daughters were having their first lessons with none other than Sukuna…

His girls don't like to listen to him.

Nao wanted to learn ancient swear words from him, at the same time Chiyo doesn't trust him the least bit. So, the first lesson was a complete time waster! When the girls returned to his side, he bore a proud smile. "Way to give him hell!" he decreed.

"We have an arrangement!" Nao said proudly. "I told him I would listen if he teaches me an ancient swear word!"

"Why learn that?" he asked.

"That way mom won't know that I am!"

Definitely his kid…

"Mom said that if we are uncomfortable with him, we can also learn from grandma too…"

He nodded to that notion as well, his girls did inherit Nobara's ability, at the same time there was something a little off about their curse energy too. They have her power, but there is something of Suiryu's hibernating within them. "We are going to have to train you, daddy can't since he's a dragon and could hurt you…" he explained.

"It's okay daddy, we know that. Besides… I think it's fun to play with him…" Nao said with a cheeky grin.

He nodded to that.

"Suiryu…" came a warning tone behind him. He froze and turned to see Yua who must have heard everything. "Girls, mind if I speak with your father for a moment?"

However, a look of dread came over them. "You're going to make us learn from freaky man!" protested Chiyo.

"No," she said bluntly. "I won't make you take lessons, at the same time… I won't waste HIS time."

"Yua?" Suiryu asked slightly bewildered to her tone. "We're just having a little fun!"

"Suiryu, I get that, but please understand how much my kids want to train with him now. I know your children and Yuuji's need lessons, they need help and the more of us who are turned, the less there are to teach." She explained. "We have the privilege of Sukuna's knowledge, and just now he is starting to share it… why hinder him in doing so?"

He sighed in defeat.

As much as he wanted to ensure Sukuna gets his, Suiryu understood what Yua was saying. There are others who are awaiting their turn to train with him, some he wants to train more than others like Rook, but he has graciously stepped aside so Yuuji and Suiryu's kids could get a step up and head start on their training and technique.

"Girls." He called. Both of his daughters stood before him proudly. "What do you want to do? Do you want to learn from great grandma? Or do you want to learn from ancient grandpa?"

"I HEARD THAT!" Sukuna roared.

Nao wanted to stick with Sukuna since she knows she is getting under his skin. Chiyo didn't want to learn from him, but she has yet to meet her great grandmother.

"Ladies…" Yua said gently. "You need to learn how to use your strength properly. As such there are not many who can teach you, I know your mother can teach you now, but you also have some of your father's power within yourself. So, you need to think carefully. Who is the best to tutor you about your strength?" she asked.

They didn't answer her, but Suiryu understood, he can't use his kids to torment Sukuna… at least for now.

"I'll speak with Nobara…" he said reluctantly. But pause as he saw Sukuna's next set of students.

Wasuke and Towa stood before him. Kiyoshi lingered near by to be their support, yet Sukuna took a seat and peered at them, perhaps seeing their technique through the energy they emit or perhaps wondering if they are going to take him seriously. Suiryu decided to take the girls home and speak with Nobara about the situation…

Kiyoshi kept his distance but watched carefully as Sukuna sat down and peered at his siblings. "Summon it," he said bluntly.

They jumped to the sudden order and turned to Kiyoshi. He smiled to them and nodded. "Call on your curse energy" he said gently.

Wasuke nodded as he called on his. He began to surge a little before tiring out. Towa did the same, but her output was a bit weaker. "I see…" Sukuna said as he leaned back a little. "Your power is just starting to grow now. For the time being technique is out of the question." He was already making a plan and strategy to help his siblings develop their talent.

They were stunned by his suggestions as well, what he had them do. "You are going to train one another. Boy, help your sister grow her strength, at the same time, your sister will help with your endurance. You tried out before she did, but you have the greater output. As such…"

Kiyoshi was rather impressed that he made a lesson plan then and there for his brother and sister. They were well behaved too compared to their cousins, but, perhaps since he was watching over them, they were more confident in themselves. Sukuna took his time to write out what they should be doing, both got a separate list from him and were told to train. "If you need help, find me." He said bluntly. "You are dismissed"

His siblings lowered their heads before rushing to Kiyoshi with the lessons in hand. Wasuke went over his sister's list and she went over his. "Oh, I don't know how to do that, do you?" Towa asked.

"I know that one, do you know this one?"

"That one was easy!"

Somehow, Sukuna pegged which one was having what problem, just by observing their curse energy alone!

"Big brother, we're going to start training!" called Towa.

"Be careful,"

They rushed back home, calling their mother and father on their first lesson. "To think, you bothered to teach…" Kiyoshi said to Sukuna.

"Not that I have a choice in the matter…" he muttered back. "The knockoff's brats don't give a damn. Their father told them to make my life hell and they certainly are capable… if I have to keep instructing them…"

"What about my siblings?"

He was silent for a moment, but then nodded. "They are going to be like teaching you." He said bluntly. Kiyoshi doesn't know if that's a good thing or not as of yet. But perhaps…

Kiyoshi stood up and lowered his head. "Thank you for instructing my siblings" he said.

Sukuna forced a laugh. "Don't thank me yet, I haven't even begun."
