You were just strolling down the street, looking for something to do since you were always so bored in your house. You thought that maaaayybe today you could hangout with the stupid sextuplets but they're basically the sources of all chaos so no.

You thought that maybe you should visit that Professor, Dekapan was it? You went to his lab thingy and greeted him.

"Dekapan! Are you there?" You tilted your head, you hear sounds of crashing and glass breaking inside and all sorts of stuff.

"Hoowee? Ah (Y/N) just in time!" He says with a smile, you waved at him but then he suddenly grabbed your hand and dragged you inside.

"Woah professor, what's wrong?" You asked him, the two of you stopped and you noticed that his desk was filled with all sorts of potions and books and papers.

"I need you to test something from me! It's really important!" Dekapan says as he lifts up an index finger before going over to his desk and pulled out some type of potion.

"Oh I-Okay?" You say before walking towards him and look at the potion he was holding.

"Is this what you wanted me to test?" You pointed at the potion, he nods with a smile.

"It's harmless I promise, it's just going to do a few changes to your body but nothing too bad" He shrugs, you raised an eyebrow. A bit unsure if you trusted him or not.

"I-I'm not sure professor, are you positve everything will be okay?" You asked him, he laughs which isn't a good sign to be honest.

"Of course everything would be okay! Why do you ask?" Dekapan asked you, you gave him a look before rolling your eyes.

"Nevermind, anyways. What does this potion do?" You take the potion from Dekapan and examine it.

"Why it does some things to your body that's for sure, but in a physical way. For example the potion can maybe turn your head six times larger than your body or make one of your arms shorter than the other, who knows what it does! It's random!" He smiles, you raised an eyebrow as you look at the potion before opening the top.

You gulped before slowly lifting up the potion near your face and drink it whole.

It tasted really wierd, a bit sour but has a sweet after taste. After you drank it, you felt yourself feel very light headed and the whole room was spinning until you couldn't even see Dekapan.

When all the spinning stopped, you look around and noticed all the furniture in the room was a lot bigger than you expected.

"P-professor? What- OH MY GOD!" You turn to the Dekapan and noticed how enormous he was! You were probably as tall as his hips.

"Oh my, I didn't think you would be like this, but it wasn't as bad as I thought!" He smiled as he looks down to you, you frowned at him.

"Bring me a mirror! I need to see myself!" You demanded him, Dekapan grabbed a nearby mirror and showed it to you. You looked at yourself and you gasped.

"Woah! What am I?! I look so short.....my head is so big and my body is so small!" You said with a gaping mouth, it's not like you didn't like it, to be honest you thought you looked pretty cute.

"I'm glad you like the body you're in, now time to make the anti-"
"DEKAPAAAAAAAAN!" You two suddenly heard someone shouting, then the doors opened to reveal the six NEETs themselves. Your eyes widened in horror.
