"Your punishment will be to become sisters. You bicker and squabbled like siblings, now you shall become such."
"W-wait, what does that even mean?" Asks Anita, panicked. The council fairy hushes her gently. "You will be bound to one another in blood and adopted by Maia." she says.
"What!?" You and Anita yell in near unison. The council fairy continues. "You will be in good hands. Maia is of good reputation amongst our grove, and a talented seamstress, who will no doubt teach you many skills. You could have far worse off than her." She says in an attempt to be reassuring. You look over and see a kindly fairy woman waving a few seats over. She must be Maia.
Anita tantrums. "No! I don't want Maia, or anyone, to be my mom! Let me go!" The council elder sighs. "Once you are an adult again, that is your decision to make. But for now, you must face the consequences of your actions. FAMILIA SORORIBUS!" She yells, casting a spell, far more powerful and impactful than any spell Anita had cast on you earlier. You can feel yourself changing, but not in any particular way. The feeling isn't unpleasant persay, just unusual.
It stops and you look over at Anita, who is just as confused as you are. Look at that dumb expression. You wouldn't even be in this mess if it wasn't for her. "Frick you, Anita!" you yell. Frick? Now you can't even swear! "Frick me?" Asks Anita, crossly. "This is all your fault, you meanie!" She runs at you and punches you. However it's a much weaker punch than before. You fight back and you're in another brawl until you're both yanked by your wrists by Maia.
Maia calmly drags the two of you out of the council room and outside. "Now now, girls. No fighting". The both of you kick and holler, arguing and begging to be let go off. "Come on, girls. There are jobs and skills to be re-learnt at home" she says, trying to coax the two of you.
"Wait, re-learnt?" You ask. Maia nods. "The regression spell that the two of you caused doesn't just regress you physically, y'know. It's part of why you two have been acting like spoiled brats." "Well which one of us is older?" Anita asks. "That'll prove who's more mature." "Actually..." says Maia "you're twins. Same age"
