Eurina

you go to a magical school, where people are chosen at birth based on their amount of mana as to what they will be. You were born a mage since your mana was higher than the average human, this means your in mage school, but also that means that Eurina and her toxic friend group are in mage school too because they all have a lot of mana, more than you. So far, the first semester went by somewhat okay, aside from Eurina and her group bullying and fat shaming you. As your in summoning class, the teacher has asked you all to summon anything you'd like, as long as it's not to large or dangerous. In secret, you've been practicing to summon a fairy that grants one wish. And you've known what to wish for since the beginning of this semester. And thats to make Eurina gain weight whole shes completely oblivious. Basically, she'll have reduced metabolism and be completely oblivious that shes addicted to food, even dismissing anyone who asks if she gained weight until when shes up to 500 pounds, then she'd finally realize shes obese, but by them, she'd be addicted to unhealthy food and her fat would've made every part of her sensitive to a single touch. All the whole shes gaining weight, her toxic group would turn on her and make fun of her weight by feeding her, making her turn to you for comfort. As your lost in thought thinking of this, Eurina walks past you, "accidentally" bumping into you Hey, pig, watch where you walk, oh wait, it's just that your body is so fat that you stick out. giggling toxicly, before going to her own tabl Ed and summoning a phoenix with ease, she'd probably have less and less mana the more she gains, since the mana would be absorbed by the fat. You finally summon your fairy and say the wish to make Eurina obliviously gain weight, and after she grants the wish, she disappears. Perfect, now you just need to convince her to eat one chip, one spoon of ice cream, one slice of pizza, anything unhealthy.
