I'm really curious as to why he was considered unsuitable and untalented as a baby. I guess they have some sort of means to measure this and that his reincarnation spelled caused an issue, but we weren't told what exactly, and it doesn't seem like he plans to venture out and meet humans. He's dedicated to living with his new family and is apparently ridiculously powerful.
Just imagine accidentally walking into that village as a newbie adventurer lol
Edit: Also, does anyone else find it weird that orcs can't understand goblins? I mean, it's a higher class(evolution). I'd understand it if was just goblins not able to understand orcs.
