"It is, in much of the world. As is my own Poison blend - I'm certain that Blood and Poison is far from what an outsider would expect a teacher to specialize in." He chuckled into his hand, but then you saw something catch his eye - something about you, "Oh my, jewelry. You don't seem vain enough to be interested in that yet. And judging by the way it's catching the light, halfsilver. Where and why were you given a Parasite Ring, my curious disciple?" He didn't seem upset by its presence, more amused if anything. "I certainly hope your family isn't allowing you to use that while you are still in the process of stabilizing your core? Your Mother should know better, as an expert in that kind of thing."
"Oh!" You realized that of all people Semis would probably be the most likely outside your family to recognize the ring and what it meant for you to be using one. But you realized that a step too late, "Well... I uh..." You tried to scramble for a lie, but in the end you just bowed deeply, "I actually already stabilized my core. Please don't tell anyone, because Tane and I are supposed to fight, and I need all the time I can get to get ready, because if I start fighting Tane I'm probably gonna get beat up really bad, and I don't wanna get beat up really bad, and even three months isn't that long and I am probably still gonna get beaten up, so please please please don't tell anyone, please?" You had tears in your eyes as you begged the teacher to hide your family's lies.
Warm arms wrapped around you, as the teacher lifted you off the ground effortlessly into a hug, "Oh little Lōkahi, do not cry. I was only teasing you. I have known your core was stable since the day you did it. I might have realized it before you even did - I am an expert in Sacred Arts and cultivating, after all. Even without a deep scan, I can tell these things." His voice was so soft and gentle as he spoke to you, "You do not need to beg or fear. I will keep your secret as I have so far." He lowered you back to the ground as you stopped crying, and started trying to talk.
"I-I-I didn't mean to lie! I just... I just... at first I just kept... forgetting! There's always things to do, and work, and studying, and trying to script better and... and then Tane challenged me and it became a secret secret and now it's scary because if people find out it's bad!" You rambled at the teacher you trusted most, and he let you do so, with a gentle smile on his face.
"Well, if it eases your worries at all, know that all your pains will be temporary even if these fights come to pass. My family ensures that every wounded participant is healed as soon as we can after the fights - it is how many of our young learn to heal more properly." He held his hands infront of hmself, as he spoke with the same gentleness, "I know it is likely a hollow appeasement, however. It will still hurt in the moment."
