Right before Natsu finds Lucy after training for one year, Zeref sells his soul to the demon Sullivan. Now in the clutches of one of the most powerful demon, Natsu is forced to become.....his grandson?!?! Wait a minute.....he has to attend school...
Zeref smiled cruelly as Sullivan stared at him with such intensity, that the moon would explode.
"I hope you don't mind..." His eyes became red as rings appeared in his irises.
"THAT I SELL YOU TO THIS DEMON!"
"I MIND A LOT!"
Natsu fell to a floor, tangled in his luxurious pillows and blankets. He stared blankly at his ceiling. 'A dream?'
His door swung open as his new 'Grandfather' rushed in.
"Good morning Natsu-kun! Let's eat breakfast together!" Sullivan, the demon he was sold to, cheered joyfully at the thought of his grandson.
Oh right, I'm in hell. Zeref sold me to a demon.
"......son of a-"
"Today is your first day of school!" Sullivan poured himself some demon tea, ignorant of Natsu's sudden flinch.
'Oh f*ck.'
After being sold to the demon, Natsu was adopted as his grandson and is now attending Demon School. But since he is human, the chance of him getting eaten are high.
'Just kill me now.' Natsu thought as he slammed his head on the table.
"Hey, uh, Gramps?"
Sullivan smiled sweetly. "Yes?"
"About school..."
"Ah right. Before that." He made a gesture to Opera, who nodded quickly and pulled a cart over.

"Look! I have tried my best to prepare them for you! All of them were woven by me and Opera! We have no experience with needlework, so it was a little bit troublesome. But we found pleasure while making them." Only then did Natsu notice that his grandfathers hands were covered in bandages.
"So, what did you want to say to me?" He gave an innocent closed eye smile.
Natsu dejectedly walked to his school. 'How can I say that to a face like that?'
Opera and Sullivan waved him goodbye.
"But really, you're truly a changeable person," Opera said monotony. "Despite the fact that you want to have a grandson, do you really need to adopt this human kid? Sometimes I don't understand your actions."
"Yeah, you're right...." Sullivan trailed off before going into, what we'll know refer to as 'Egg mode' and was beginning to follow Natsu with a camera. "I must raise him by myself, that's the best way! We're going to be very busy."
Opera grabbed him by the shoulder and started dragging him back inside the house. "Today is the first day, you must fulfill your responsibilities at home first."
