Can't I Be a Little Selfish as the Demon King's Daughter?

I, Belorin! The cute and charming princess of the demon world!! The only daughter of the debt-ridden Demon King!!

I'm obsessed with games, and my greatest wish is to live happily ever after with my favorite character, the Flower Sword Princess "Ail"!

"Lady Belorin, I've prepared a gift for you."

"...If it's nothing important, don't bother me!"

"I've prepared your very own 'Ail.'"

"W-Well, I suppose there's no helping it... Catherine!"

After that, I followed the young lady who served as my butler to a room in the castle basement.

That was how Ail and I first met in real life.
