Nekomimi characters cover the side of their heads with hair.

So...

What happens if...?

"Hmmm…."

"Hmmm….."

"Hmmm…." Noah groaned, playing with his ponytail.

"What's wrong, Noah? You seem concerned…" Eunie said, sitting next to him.

"Something bothers me…"

"What?"

"Mio…" Noah said, with a serious face.

"Mio? What, about her lifespan? If you mean that, everyone is worried about it, love."

"Not that…"

"Huh? Then what?"

"About…her…ears…"

"Oh, her ears? You still not used to her cat ears? If you're not used to that, how are you used to my wings?" Eunie said, flapping her wings.

"No, not that."

"Then…what is it?" Eunie now looked irritated.

"Okay, I'll explain. You know that we have ears around here, around our temples?" Noah said, pointing his ears.

"Yeah, here." Eunie said, twitching her ears.

"Whoa, you can move ears?"

"Yeah, never told you?"

"Yeah… Anyway, we have ears around our temples… But Mio has ears up there…And she covers her temples with her hair…Then…."

"Ooh, now I get it, love."

"What would happen if we moved her hair up?" After saying that, Noah looked at Eunie.

Eunie stared at Noah.

"So, how do you think, Eunie?"

"Mate."

"What?"

"That. Was the best thing. That ever came out of your mouth. Like…holy sparks! My brain is literally getting filled with theories! What would it be? Would…planes of skin appear? Or a new pair of ears?" Eunie said with her eyes wide.

"Come to think of it…Hadn't you seen her when you showered together?"

"Yeah, but think, Noah. Would you approach her from the back just to lift her hair when she's naked?"

"Well…You're Eunie, so…"

"Come on, Noah, had I pranked with you when we showered together?"

"…"

"Come to think of it…"

"Yep, you did."

"Bollocks…Anyway, back to the point."

"What are you guys talking about? Let me join!" Lanz said, as he returned from his workout.

"Oh, great timing! You see…"

(After some explanation)

"Yooooooo…..!"

"Great idea, innit?"

"Yup! Can't think of a better one. So, when are we going to do it?" Lanz seemed thrilled.

"How about next morning? It's getting late, so we can't run around like maniacs." Eunie said.

"Tomorrow morning?"

"Tomorrow morning."

So, the operation of lifting Mio's hair was decided between the Keves trio.

And…the sun rose.

Time to start.

"Time to leave now!" Mio said, putting her hands together.

"But before we leave…don't we have something to deal with, love?" Eunie said, squatting down. It was her signature pose now.

"Hmm? What is it?"

"Mio," The Keves trio said in unison.

"Ye..yes…?"

"You have ears on top of your head, innit?" Eunie said, leading the team.

"Yes…?"

"So…what happens when you lift your hair…covering your temples? Where our ears are…Mio…?" Before Eunie could even finish her sentence…Mio started to run.

"She's…running…but why…?" Noah said.

"Why? Of course, dummy! She found out our thing!" Eunie said.

"Looks like there's only one thing to do…."

"Catch that cat!" Eunie shouted.

"Catch that…what…? Guys?" Sena said, as she came back from somewhere. And it seemed Taion was absent, too.

"Sena…? Where have you been?" Lanz asked.

"Uh…you know…since it's morning…you know…toilet…?" Sena said, scratching her flaming head.

"Then how about Taion?" Eunie asked.

"He went to fetch some water."

"Oh yeah…we needed water…" Noah said to himself.

"Lanz," Eunie said.

"I know, I know. Sena, sorry but…I need you to be still." Lanz said, approaching Sena.

"What? Why?"

"We need to do…something. So…"

"Uh…Lanz? Why are you approaching me like…"

"Come here!"

"AAAAAAAAAAAACK!"

"Thanks Lanz! Come on, Noah, let's go." Eunie said, grabbing his hand.

"On it!"

(After some running)

"Hah…hah…hah…why is she…so sparking fast….?" Eunie panted.

"She…did say…she did 100 meteris in 7 seconds…." Noah also panted.

"Why are you guys here?" Oops, there was Taion.

"Oh, Taion….?"

"Oh shoot… Four eyes…"

"You look tired, what's up?"

"Taion, do you know where Mio is?" Noah asked.

"Mio? I did see her running somewhere…but why?"

"You see, Taion, we're doing…some kind of…project…" Eunie said between pants.

"Project?"

"It's this, we first started as…."

(After some explanation)

"So…you're curious about her ears…but she just ran?" Taion said.

"Exactly. You interested?" Eunie said.

"Then…where's Sena?"

"Her? Hmm…she went to the latrine." Eunie replied.

"Why can't I trust you…?"

"It's your choice, but I think you're gonna be interested in this…"

"Hmmm….her ears…they seem interesting indeed…"

"So you're in?"

"But…is it alright to force this?"

"We can decide that after we catch her. How's that?"

"Ugh…Okay, got it. I'm in. I'll assist with all of my might."

"Sweet! Noah, let's get going!"

"Got it!"

(After some running)

"Hah…hah…hah…my…heart…is…about to…" Mio moaned, collapsing down.

"Give up, Mio. There's nowhere to escape when my Mondo got you." Taion said, slowly walking towards her.

"Whoa, four-eyes, you caught her quick!" Eunie exclaimed.

"Mio, you alright?" Noah said.

"Why…why are you chasing me…?"

"Then why are you running? We didn't chase you from the start." Eunie said.

"Where's Sena…? Sena! Help!" Mio shouted.

"Oh, Sena? Lanz tied her up." Eunie casually said.

"What? You said she was in the…"

"She 'was', love. She's probably having a good time with Lanz."

(Sena side)

"Come on, Sena, be a good girl," Lanz said, stroking Sena's hair.

"MMmmmMmmmMMmmMmMM!" (Why are you doing this!)

"Relax, girl, we're just curious about something."

"MMmmMMMMmmMMM?" (About what?)

"Have you ever been curious about Mio's ears?"

"MMM?" (Ears?)

(After some explanation)

"MMMMmmmMMMmmMm!" (So what the spark does that thing get to do with me!)

"Thought you'd stop us, so Eunie signaled me."

"MmMMmmMMMmMMM!" (Untie me!)

"No,"

"MmmmMMMmmMMMmmM….." (I swear I won't…ah….)

"Hmm? What's the matter?"

"Mmmm….." (Toilet….)

"Again?"

"MMmMmMMMmMmmmm?!" (Can't a girl can manage her business?!)

"Okay, okay, I'll send you free, but don't cause trouble."

"Mmmmm…" (Finally….)

(Mio side)

"Yeah, that happened."

"The sparks sake…" Taion facepalmed.

"Anyway, Mio, love. Time for the dramatic reveal! Drum roll, Noah." Eunie said, as she slowly approached Mio.

"Ah…ah…aaaah…please…no…Eunie…" Mio almost sobbed, as she slowly stepped back.

"Come on, love. It's not like I'll strip you off here."

"But…but…"

"Now come here, you little kitty!"

"Aaaaaaaahhhhh!"

(Omake)

"Man, what a reveal!" Lanz said, as he walked with Eunie.

"Yup, didn't imagine our curiosity would end like that." Eunie said.

"But that….was pretty unexpected though…" Said Noah.

"I can't believe I did this thing for that…." Taion sighed.

"But wasn't that worth it? Man, I feel like we've already reached the City!" Lanz said.

"Yeah, one mystery solved," Eunie smirked.

"But that…still can't believe it," Noah said.

As the four horsemen of cat-ears trod off, there walked Mio and Sena.

"Mimi…you alright…?" Sena said, patting Mio's back.

"*Sniff* I…feel…like…I've been…spoiled….*Sob*" Mio said between sobs.

"It's okay, Mimi. You have me! So don't cry…."

"Sena….Senaaaaaaaa…." Mio said, crying into Sena's small chest.

"It's okay, it's okay…." Sena stroked Mio's hair.

'But this is indeed intriguing…What would happen when I lift…Nono, focus on Mimi.'

And behind Mio and Sena…

Let there be Nopon.

"Why friends say that all the time? What does that mean?" Manana said.

"Manana,"

"Yes?"

"There is things in the world, that is never meant to be revealed. That is one of those."

"But why hide?"

"Because, readers must not know."

"Readers?"

"Manana need not know."

"Rikuuuu! Manana want to know!"

"Riku smart nopon, Riku never do something stupid. Riku never reveal that."

"Manana can't understand what Riku saying…."

I am smart Authorpon, so Readerpons can never know about the secrets of Nekomimi.
