My little sister is too cute, so I have to protect her!

"Urgh..."

I woke up to the sound of the school bell ringing... -Not

What actually happened was when all the classes are over, Charlotte came over to slap my face.

"Onii-chan... Let's go, shall we?"

She said that as she dragged me by my collar.

"H-Hold it!!! Who said that you can take him?"

"Hanako Onee-chan... You see... Even though we are not related by blood, I am his sister, and as a sister, I have the right to know what her brother is doing, yes?"

"Hn... I suppose..."

"So when her brother decided to get a girlfriend and didn't tell me about it, he deserves to get a little 'punishment', yes?"

"W-Wait! You can't do that!"

"Don't worry, Hanako Onee-chan, I only see him as my brother, unlike Mio, who sees him as a love interest."

"Oh, is that the case then? Okay! Beat the crap out of him, Charlotte! He deserves it!"

"O-Oi! Hanako! Don't abandon me like this!", I retorted.

In reply to my retortion, Hanako stuck out her tongue playfully and waved goodbye to me while I got dragged away into the distance...

************

"C-Charlotte... I-I can explain it!!!", I desperately tried to calm Charlotte down.

"Onii-chan♪"

"Eek!!!"

"Don't worry, Onii-chan. I won't hurt you~ I'm not Mio, you know~"

"Charlotte...", I looked at her as if I saw an angel.

But before I could savour how beautiful she is, she immediately made a devilish smile.

"But you'll have to comply to one of my request, okay?"

"W-wha?"

"Don't worry Onii-chan, it's quite simple, actually ♪"

I started to worry what her request may be.

"All you have to do is get your parents to sign this document within the next 24 hours, or else I'll chop your limbs- oops, I mean I'll reprimand you~", she said that as she handed me an envelope.

"You definitely said you're going to chop my limbs there, right?!?!"

"♪"

"Oi!!!"

Since it seems that she won't be accepting no as an answer, I opened the envelope that she handed me. Once I pulled the documents out of the envelope, I was at a loss for words.

"Nee, Charlotte?"

"What is it, Yuuji Onii-chan?"

"Uh... What is this?"

"It's exactly as you see it, Onii-chan ♪"

The label on the top of the document is 'Adoption Application'.

"Oi!!! Don't act so nonchalantly, Charlotte! You know that your parents will never allow this!"

"Oh~ Don't worry, Onii-chan, I've already made the necessary preparations."

"Huh?"

"My father was very against it at first, but when I gave him a picture of me in my swimsuit, he immediately agreed to this matter."

"Oi..."

"My mother dotes on me all the time so she also supports my decision. See? No problems at all!"

"..."

"Besides, our parents are old friends, there definitely won't be any problems!"

"Give me a second, Charlotte..."

Before I decide on anything, I took out my cell phone first and dialled a certain number. I turned towards Charlotte and asked,

"You have no problem with me reporting your father, right?"

"No problem at all~"

"Hello, this is 911, how can we help you?"

"Uh... There's a perverted father who lusts after his daughter's body who lives in London..."

I gave the police a rough description of the situation and then hung up.

"Let's discuss this matter at home."

"Okay♪"

Thus, I quietly walked back home with a slight headache...
