Nightmare's Castle
"I've brought you here to talk about the child." Nightmare told them.
Killer and Cross sweat-dropped as they thought of all possible reasons why they could be having a meeting about this, all concluding in something dark or horrible.
Horror just sat confused as Dust showed no expression. "There's a child?" Horror said confused. When he looked around at the others, he realised he was the only one that had no idea that this child exists.
"Did you really not introduce Horror to the child?" Nightmare asked. "She's a human boss! I wasn't sure how he'd react.." Killer answered.
Horror just gazed between them, completely lost. He looked at Dust and raised a bone brow. Dust looked back and shrugged, letting a smirk appear on his face. Horror frowned at the fact Dust knew too and never told him.
Cross then asked, "Are we ever going to introduce the kid to Error?" This question caused Killer to panic. He had no idea how Error would react, he didn't know Error that well.
Cross noticed the panicked look on Killer's face and quickly tried to calm him down.
"Well, this meeting was called to discuss the plans we have for this child." Nightmare said.
They all turned to listen to him. "I can feel intense power coming from this child. I expect no one to try and cause any form of harm to it as she will be very useful in the future."
"Killer has been put in charge of the child. He has full permission to do whatever he wants with her, as long as it doesn't cause harm. Causing harm to the child will result in serious consequences."
"It is Killer's choice whether to grant the rest of you the permission to take care of it too. I see Cross has already earned his trust."
Cross smiled at this, proud that he was trusted.
"Killer, I trust that you will start training at whatever age you think they're ready."
"Yes boss, I won't let you down." Killer says, getting ready to leave.
"That concludes the meeting, go back to whatever you were doing." Nightmare says boredly.

5 years later: the child is now 5 years old.
"Ready for your first lesson, [y/n]?" Killer asks with a smile.
"Ready!" The 5 year old says determinedly.
Flashback
The 3 year old ran around the halls giggling, currently being chased by Killer because she needed a bath.
Killer just reached, but just as he was about to grab her arm, she started floating, but this wasn't Killer's magic. He always avoided using magic on her at such a young age as a way to avoid traumatising her accidentally.
Killer stared in awe as the small child floated in the air, tumbling around. "Magic! She has magic!" he exclaims excitedly.
Flashback end
That day was the deciding factor that made Killer agree that earlier was the best time to start training, Which is why they are here today starting their first lesson.
"Great! Now our first lessons will be learning to control your magic. You think you can do it?"
"Heck yea!" They exclaim excitedly.
A/N
Short chapter because I need to plan out exactly how the training plays out and I don't wanna keep u waiting. Enjoy this for now :)
