Gently, Sashi-san shakes her head. "Okido-san was born in the last year of the last century. Even to a mage, there is little difference between a true norm and one who carries the elf genes, one who is an elf but was born too soon for the elven qualities to find expression. Yes, the right mage might detect a difference, might see that Okido-san is purely a norm, but the point could never be prove absolutely. And a mere shadow of suspicion would bring everything to ruin. Surely you can see this."
