It is weird that he has a different hair color from both parents but it could be explained with a grandparent having that hair color.
It'd be funny if we see one of the ring leader's parent and their hair color is the same as kiritaka
It’s not uncommon for a child to have different traits from their parents. They could have inherited it from the grandparents. That like two brown eyed parents having a blue eyed child. DNA is complex.
im really bothered how kiritaka friend (yuda Kun) having a look a like with kiritaka's father(detective) and they all have dark hair while kiritaka have this different hair color?
now I'm curious if kiritaka is their real child or he got switch. he doesn't even look like his parents.what if yuda is their real child? hahahaha
ps. rest in peace kiritaka.. hope you achieve your dreams to be detective on your next life.
