Sofia Johanneke, your best, and oldest friend. You two have known each other for... well, forever. You met all the way back in elementary, and you've been friends throughout middle, high, and even mage school.
She was always an incredible witch, but a witch is always nothing without a Witch Hat, (at least according to the Headmaster). So, she did something stupid. Something very stupid. She ventured down into the catacombs beneath the school, looking for a Witch Hat. It was said that as long as you could defeat the monsters that laid in wait, a Witch Hat would be your reward for your troubles. The monsters were of no issue, even as a witch that specialized in healing, she was still more than capable of defending herself. And that... that she did.
She reached the end, and... clearly, she found something. A Witch hat. A strange Witch Hat. Ever since she left that dungeon, she just hasn't been the same. Not even close. Like a shit actor attempting to replicate the performance of a popular star. She never takes it off, either. Never. Not even when she sleeps. It's genuinely worrisome... That, and she never blinks. She breaths loudly and heavily. She seems to stumble around like a drunkard too.
... You should probably check on her...
