And why wouldn't Julia be a real Kitsuni? Kitsuni are famous for disguising themselves as human, The MC's family has some muddy blood lines, and nothing has demonstrated the Julia is the MC's sister by blood (given the shady mother background).If he does add a real Kitsune my money is on Madam Daiyu. Wouldnt be surprised if the asian woman that runs a magic potions shop turned out to be some kind of yokai.I think Tinkerer is testing the water for a real kitsune, especially the tail part
PS, yes I can see the tail is a butt plug. Doesn't mean she can't be a Kitsune cosplaying as a human cosplaying as a kitsune
God I love the Kinsune sense of humor
