(Updated whenever inspiration strikes.) Heaven and earth are dark and yellow, the universe vast and wild; the sun and moon rise and set, and the stars are arrayed in order. Cast out as a sacrifice to calm the universe's fury, a victim of war within her clan. The weakest among the Demon King's successors lies asleep beneath a thorn-covered land. Your task is to awaken her and raise her to adulthood.
Welcome to the Great Demon King Raising System. There are four stages in total, and you can claim the corresponding rewards at each stage.
(Note: You can raise her frugally or lavishly, but do not be harsh with her or hit her at random.)
(Note: An underage Demon King differs from an adult in every respect.)
(Note: Please don't expect to use her powers to do bad things.)
Finally, have fun!
The person in front of the screen tossed his phone onto the bed, his voice full of anger. "Ugh! This is so infuriating! What kind of game is this? You can't even delete it! I spent so much money, and the rewards don't work even when I tap them. Did I just tap for nothing? What's the customer service number? I want to report them!"
After a flurry of urgent knocking, the door was suddenly flung open.
"Bro! Something terrible has happened!"
"There's a little girl outside saying she's your daughter!"
"Is she really your illegitimate daughter? Why won't you let her in? Do you know how dangerous that is?"
"And she's so adorable! Did you bring her here, bro?"
The situation was extremely awkward.
"...Hey, Robin, would you believe me if I said a character from my phone game had come to life?"
"And she's not my illegitimate daughter! Stop looking at me like that! She's my little sister now! She's your little sister too, got it?"
Not long afterward, as he watched the two of them holding hands, he fell into deep thought.
"Hey, come on, act like a decent person. You watched her grow up. You even picked her name..."
"Exactly. I picked her name, so she's mine."
"???"
She's the weakest little one in terms of powers, so she can only get by on her cuteness.
