his sisters are not his biological siblings. In early chapters it's been told that his current deceased slave parents picked him up as a baby from the road where corpses lying around.
The slave parents have those twin sisters biologically. But not him.
Oh yeah, he was picked up from the road I forgot. That's one question answered
My parents always joked that they picked me up off the side of the road, but Niro's parents really did. (￣ε(#￣)Σ
He's royalty?! WTF that shocked me I knew he was half elf but royalty?! That leads to so MANY questions! How did he get to his family? Was he abandoned and then found?! Is his sisters even his sisters?! Did his dad have an affair with the queen? Why did his parents lie to him about his origin? Did they? Who's his real father? How does his mother look like?! My head is literally being BOMBARDED with questions(￣∇￣")
