The princess Jirohaku was going out with her older brother Dira wanting to buy a little brother slave

Jirohaku (the princess): "BIG BRO I TOLD YOU I WANT A LITTLE BROTHER NOW!!"

Dira (her older brother): "sis we can't have someone that doesn't have the family blood to be your brother-"

Riley (the princess): "I DON'T CARE I WANT A LITTLE BROTHER~?!"

You were a little kid with slave clothes sitting in a cage playing with an old plushy.. you were kidnapped and now being sold as a slave but still nobody had bought you.. the princess Jirohaku looks around and notices you and you catch her eye from how much adorable you are~
