Chapter 3: Who Is My Little Sister?

I stand there with my eyes wide. this lavender haired girl just called me Onii-sama.

"Onii-sama? Then you're my..."

"That's right Onii-sama! Whenever you want to see your little sister just come on down to my store!" She advised.

"Store? What store?" I replied.

She looked at me surprised.

"You don't know?"

She put a flier in my face. i took it and read it.

"Little sister cafe: lyrical Sisters?" I read aloud.

"Yep! it's a fantastic cafe that allows anyone and everyone to become an older brother or sister! I'm the owner, Sagara Blaze, I'm a Third year student here!" She announced.

'So she's not really my sister' I thought.

Then i relaized something, my jaw dropped.

"Third year? You're my Senpai!"

"I work at the store to get a better understanding, you can consider it my free service for you Onii-sama." She said pointing her wand at me.

She said it like it I owe her something.

"So Why have you been stalking me?" I asked her.

SHe adjusted her glasses before answering me.

"because i am also the child of a working family! I wanted to know how another child of suck a great working man lived his life."She replied.

I sighed,

"Oh that doesn't really make sense."

I left the hospital and looked over the paper in my hand.

"I skipped school to look at mt family register, but that didn't make a difference. There's no recording of a little sister here at all."

I began to walk away when I felt something press against my back. I froze as behind me stood a man with a black cloak and sunglasses held a knife to my back.

"Don't make any sudden moves! Just walk over into that alley." He whispered.

I complied. When we were in the alleyway itrned to him.

"Who are you? What do you want?" I asked.

"You may not believe it but this was my only way to talk to you privately. I am Mr. X."

He took off his hood and sunglasses. He was a red echidna with purple eyes.

"I work for a secret organization that handles all of the Mikadono groups troubles."

"What does your special unit want with me?" I wondered.

"Allow me to be direct, why are you investigating youe father? Are you trying to find out the identity of his secret child?"

I gasped at his statement.

"I seem to be correct."

"My father had a secret child? Is it true? Do I have a younger sister?" I asked.

" It would seem so." He replied.

"Seem?"

"Your mother once confided to an aide, that your father seretly had an illigitiment child after an affiar with a mysterious women." He explained.

"Then those phone calls I've been getting..."

"Phone calls?"

"Yeah, I've been getting phone calls from someone who claims to be my younger sister."

"I see."

"But not only that, she may want to marry me."

"Marry you? She said that over the phone?"

"Well not exactly."

I told him about the day of my fathers funeral, and how my "little sister" showed up and said she would marry me.

"This isn't good. If you marry a blood relative then it would be a major scandal for the Mikadono group." He noted.

"It wouldn't just be a scandal! It's illegal!Besides if that did happen, I'm sure my sister would be unhappy. If I do have a sister, then I would never want her to be unhappy."

"Sonic-kun, have you become friends with any girls lately? She may be trying to get closeto you."

I thought about Sally-san, Amy-san as well as Kunitachi-san and Tendou-san. I also remembered earlier when I met Sagara-senpai. Anyone of them could be my little sister!

"I'm Misutani Knux, and I will be joining your class starting today!" The red echidna smiled.

I couldn't believe it. Not only did this guy just transfer her but Misutani Knux? Mister X? He couldn't think of a less obvious name if he tried!

"Nice to meet you all!" He smiled giving a wink to the girls.

"He's so hot!"

"His face is so beautiful!"

"I'm so glad i'm in this class!"

"Alright, now you can sit right in front of Mikadono-Kun." Hitori sensei instructed.

He sauntered over and sat in front of me. he turned his head and gave me a thumbs up.

"What is going on!" I demanded.

Knux-kun and i were on the roof of the school.

"Psst, it's me Mr. X! We met in the alley." He whispered to me.

"That's not what I'm asking! Why are you here at my school?"

"To protect you from the evil hands of your little sister of course. if your sister does indeed go to this school then she will attempt to get close to you. So I decided to enroll here so that I could keep and eye on you."

"Well how will you know of this girls my sister or not?"

He held up a cyeinge.

"With this. If you can inject this into someone then they'll drool like a dog. It's actually pretty funny. It lasts for about a week, and the only lasting effect is some slurred speech."

"That's wrong on so many levels."

The door opened and Sally-sab and Amy-san stood in the doorway.

"Sonic-kun, are you ready to go home?" Sally-san asked.

Before I could reply Knux-kun clinked arms with me and smiled.

"Sorry, girls but i'll be walking Sonic-kun home today!" He announced.

Amy-san and Sally-san stared at us awkwardly. He dragged me off the roof and to my apartment.

"Did we really have to link arms on the way home?" I asked.

"We had to make sure not to draw attention to ourselves."

"I think we caused a pretty big misunderstanding. Well whatever. Make yourself at home."

He entered my apartment and looked it over.

"Hey, Sonic-kun, can I use your shower?" He asked.

"Sure why not." I shrugged.

He nodded, but before entering the bathrrom he looked at me.

"Under no circumstance must you peek!" He noted.

"Like hell I would peek I'm a guy too!" I yelled.

As I heard the shower turn on I remembered that I had hung my towels out over the balcony to dry. I went out to grab them and brought one to him.

"Hey Knux, Iforgot that my..."

Standing there in my shower was an orange female echidna with a surprised expression. Her body was fully naked and my towel dropped from my hand.

"A girl?"

"So you're real name is Misutni Tikal-san, but you changed it because only men were allowed in the organization. ANd this would help you fulfill your dreams of being a real life ninja." I sighed.

"Yep. I hope this doesn't make you uncomfortable." Tikal-san smiled as she sat on my bed.

"I'd be more comfortable if you would put some clothes on!" I sighed.

Tikal got up and walked into the bathroom. She returned wearing her school uniform and held a red wig. She put the wig on and was itantly Knux-kun again.

"I'd appreciate it if you continued calling me Knux-kun." She smiled.

"Fine, whatever." I sighed sitting down on my bed.

"By the way Sonic-kun, while I was showering I had a brilliant idea!" She informed sitting down in my desk chair.

"What idea was that?" I asked.

"We should get married!" She proposed.

I caught my breath.

"If your mysterious sister tries to approach you she won't be able to marry you anymore!" She smiled slyly.

"Mariage! But, i'm not emotionally ready for that yet!"

"Why not? It's easy, we get married have chldren and then we can have a happy family." She smiled.

"Do you even know what you're saying?" I asked with a blush.

"Well i believe you make children by lying on the bed holding each other." She explained.

"Like hell you do!" I shouted.

XXX

"I see, so that's ho you make children." She said reading the book I gave her.

"Yeah, so do you get the picture now?"

"So the sperm fertilizes the egg and..."

"You don't have to repeat it!" I yelled.

She stood up,, and bgan undoing her tie. She dropped her jacket and tie on the floor and turned to me.

"In that case making a baby seems like a rather complicated process so we shoul begin practice immediately!"

"Wait no don't...!" I began.

She laid down on top of me. I tried to push her off. Suddenly my door opened.

"Sonic-kun good morni-waaaah!" Sally-san gasped.

Amy-san was there too and her eyes just widened when she saw us.

"No, this is..." I stammered.

"Don't worry, we are only practicing making children. We are not doing anything nnapropriate." Knux-kun stated.

"But, you're two men..." Amy-san stated.

"Making children?" Sally-san repeated.

I noticed a trail of drool seep from Amy-sans mouth as she blushed.

"WHAT!?" The two of them shouted.
