"W-what's going on? This is too weird!" Nico said with a terrified expression despite achieving some of the growth she seemingly desired "I wanted to grow but not so suddenly! W-what if I grow too much? I could no longer be an idol!"

"Nicocchi.." Nozomi interrupted Nico's breakdown with an unusual timid tone "could we get our friends here?"

One look between the two friends was enough to understand something, that neither of them knew what exactly was happening. Nico nodded and ran to search for the other μ's members while Nozomi kept looking at the height rod.

It didn't take long for Nico to retrieve all the members, Eli was doing her student council work and the other girls were all in the classrooms. They didn't hesitate to drop everything and follow her to the nurse emergency to check on Nozomi as she requested, only noting among themselves that Nico looked a bit different but thinking it was cause of the emergency.

"Ehh?" The girls predictably gasped once they got a good look at what was going on. 

"Nico-chan is.. tall now" Kotori said

"But Nozomi.." Eli said looking down at her friend. Normally there was only an inch of difference between the two but now she could look past her head as she could with Nico. 

Nozomi looked up, feeling slightly intimidated with this new perspective even if this was the same Eli she had shared so much with. Looking at the other girls she gave a small startled shriek as they seemed to forget about Nico and were eyeing her curiously.

Maki, the second tallest in the group, also got closer which made her take instinctively a step back. Putting a hand on her head she lined it and with just above her eyes, something that made Nozomi feel strangely inadequate. But she was too self conscious to display it.

"You're smaller than everyone now" Maki said, disbelief clear in her voice

"Even me?" Rin asked and indeed, she looked to Nozomi just like Eli used to look, an inch taller.

"And Nico-chan looks as tall as Nozomi-chan was before" Kotori looked at Nico who was now seemed just a hair taller than her now.

"That's strange, definitely an emergency" Honoka said, Umi and Hanayo just nodded still making their silent judgments of the situation.

"We don't know what's going on, you have to help us!" Nico pleaded once they stopped the height comparison

"But how?" Eli said "Should we get a doctor?"

"We don't know what's going on, it just happened" Nozomi said finally recovering from the slight shock and strange feelings

"Could it be a virus in the school?" Hanayo asked timidly

"No way!" Honoka said "We can't get sick! It would interrupt our practice!"

"That's your main concern right now?" Hanayo retorted

"Nozomi-chan, Nico-chan, what were you doing before this happened?" Umi asked

"I was just teasing Nicocchi as usual when"

"That's sexual harassment!" Nico interrupted

"Then Nicocchi got mad just like that and next thing I knew things looked different"

All the other girls could do was gasp in surprise
