(This is based off of those cringy povs. So everyone gets a mark on their arm and there is only one other person that has the same mark which means they are your soul mate. So this is the hunter exam part and your minding your own business and illumi is with his friend hisoka and waiting for the challenge to start and other people keep coming. Oh also just to be clear. Illumi is your soulmate and you both have a black moon for the mark.)
