Yue was excited beyond belief; today was the big library expedition day! She had all her gear, provisions, and and strange tasting juice boxes packed into an extremely small back pack. As she walked outside she saw her teacher, Negi, standing with his staff in his hands. "Incresco Tantus!" she heard him yell. A flash of blue light launched off his staff and struck her full force in the face. The impact caused her to fall to the ground immediately. She saw (or rather, felt) Negi running towards her.
"Yue-san! Are you alright?!" he squeaked.
"Ahh! Y-yes, Negi-sensei, I-I'm fine", she said as she stood up, clutching her face. She felt herself sway as if she was a reed in a river. She fell back down flat on her butt and rubbed her head.
"That was weird. I feel off-balance for some reason."
"Umm...Yue-san, could you open your eyes please?" Negi whispered. As she removed her hand she saw something that made her rub her eyes in shock; her teacher was floating on his staff above her gigantic right knee.
"The growth spell seems to have worked, though this isn't exactly how I planned. It was supposed to hit a rock and-".
Negi was soon silenced by a finger roughly the size of his whole body.
"It's not a good idea for us to talk about that kind of stuff here. Even if it is really early in the morning, we should find a more secluded spot to talk about what happened", Yue whispered as softly as she could to Negi. He simply nodded and hopped onto her ready palm. She stayed low and under the trees as much as her much bigger body would allow. As soon as they found a place to talk she sat with her back against a tree and looked straight at her teacher.
"Alright, sensei. What happened?" asked the 60 meter tall giantess Yue. "Why am I so big??"
"Well, like I said, it was a growth spell. I don't know why it missed the rock and hit you, but it did for some reason."
"A growth spell, huh? Wait a second..you do know how to fix this, right?" Yue asked, looking worried.
"Well. The truth is...n-no. I'm sorry, but I only know how to make things grow, not shrink them. It may take a while before I can probably fix it."
"Oh no! I'm going to miss the library expedition today! This is the WORST!" she pouted. It was the first time Negi had seen her be so emotional about something without crying. This sight was not to last, however; shortly after a torrent of tears flowed over the boy's body, drenching him from head to toe.
"Please don't cry, Yue-san. It's my fault! And as your teacher, I'm making it my responsibility to fix it."
Negi looked quite confident in himself as he proceeded to take out his staff once again and make a noticeably bigger circle in the dirty around his giantess student.
"I'm going to try my best at this and try to see if this spell will reverse itself. Here goes!"
"Negi-sensei.." Yue said between sniffles. "B-Be careful.."
Did Yue get smaller, or were her problems just about to get even bigger?
