The next morning Leo walked over to the nurses office before school started, when he arrived he saw sasori being healed by a tall woman with brown hair and blue eyes she appeared to be wearing a lab coat with a pencil behind her ear. She placed some small healing items herbs and small amount of powder on sasori arms, then holding a hand over sasori's arm the items began to sink into her skin fully healing her injuries.
"There you go, now please dodge out of the way next time something is flying toward you" the woman said to sasori in a condescending voice but sasori nodded in a shy way to say I understand, sasori stood up and walked to the door and saw leo "oh hi I was getting my injuries healed" "I see that" leo responded in a sarcastic way and they awkwardly walked passed each other.
The woman said to herself quietly "teenagers" she then stood up and said to leo with an outstretched hand "hi I'm cleric, the nurse for U.A." he shook her hand and sat down "now why are you here Leonard koto", this didn't surprise leo sense Cleric probably had he's entire health record on the computer behind her "I've had these small patches of diamond on my arm for a few years" he holds his right arm and continued "my father" he said with venom "told me thay would go away eventually but It's got worse" he pulled up the sleeve of his blazer to revealed that a good chunk of the centre of his right forearm had completely turned to diamond.
A very worried look feel over the woman's face "I've herd of this but rarely, it's happens with similar quirks like yours, it forms because of over uses of the quirk. But leo these is continued over uses, if it was weaker I'd say to not use your quirk for a few days but this" leo then cuts her off "but I can still fell contact to it" she then nodded her head "sadly i know, through over using your qurk your arm is now fusing with the material you over used, in this case diamond.
You will still be able to feel with it since it is also fusing with the nerves in your arm, did the spots ever appear anywhere else?" Leo spoke cautiously "on my right hand as well, but they disappeared" cleric looked at him with pity "it will spread to your hand and just around your elbow" she said pointing to were it would stop "leo how did this happen? this isn't a few days of over uses this is weeks maybe months" leo broke eye contact "it started to get worse a few weeks ago". Understanding that she wasn't going to get the truth she put a hand on his shoulder "ok, come to me every few days so I can document the spread and help you through it. It's eight forty five go to you class I'll see you in a few days" leo nodded then left rolling down his sleeve, he wore his backpack with on arm while staring at his right hand he bumped in to kuno who saw the sad look in leo's eyes "you ok?" kuno said with confusion "yea I'm fine, let's go to class"
